Notes and Known Issues Activation Lock Note Activation Lock is enabled on your Apple Watch if you have Find My iPhone enabled on your iPhone.
Connectivity Note Enable "Install All Apps" in Watch.app -> General -> App Install for WatchConnectivity to work correctly during Build and Run cycles.
Keychain Note Keychain items created on an Apple Watch are not viewable on an iOS device.
Maps Known Issues If you do not see map tiles load on the Watch Simulator, launch the Maps app in the iOS simulator first. After that, map tiles will load. The MKMapItem method openInMapsWithLaunchOptions: does not work. WatchKit Notes WKInterfacePicker has a new method to remove focus. The method focusForCrownInput has been renamed to focus. Installing a WatchKit 1.0 app with an Xcode prior to 7.0 requires that "Automatic App Install" be enabled in the Watch app under General -> App Install.
iOS SDK 9.0 provides support for developing iOS apps. It is packaged with a complete set of Xcode tools, compilers, and frameworks for creating apps for iOS and OS X. These tools include the Xcode IDE and the Instruments analysis tool, among many others.
With this software you can develop apps for iPhone, iPad, or iPod touch running iOS 9. You can also test your apps using the included Simulator, which supports iOS 9. iOS SDK 9.0 requires a Mac computer running OS X v10.10.3 (Yosemite) or later.
This version of iOS is intended for installation only on devices registered with the Apple Developer Program. Attempting to install this version of iOS in an unauthorized manner could put your device in an unusable state.
By default, the iOS 9 beta automatically sends anonymous diagnostic and usage data back to Apple. This includes information about crashes, freezes, kernel panics, and information about how you use Apple and third-party software, hardware, and services. This information is used to help Apple improve the quality and performance of its products and services.

Notes and Known Issues
The following issues relate to using iOS SDK 9.0 to develop code.
Accessories
Fixed in Beta 5
Lightning video dongles don’t work with this beta.
App Store
Note
iOS 9 enforces the UILaunchImages requirement; apps can no longer declare the same launch image to support different interface orientations.
Known Issue
Users might be prompted twice for credentials on the first In-App Purchase.
Apple ID
Note
Some users will be offered the option to upgrade their Apple ID to use two-factor authentication. For more information about two-factor authentication see developer.apple.com/support/two-factor-authentication. Two-factor authentication is not supported on iOS 9 betas prior to beta 3.
Fixed in Beta 5
You may not be able to create a new Apple ID in Settings or Setup Assistant.
Workaround: Create a new iCloud account on iCloud.com.
You cannot manage your two-factor authentication trusted devices at appleid.apple.com.
Workaround: You can find and manage trusted devices in Settings > iCloud > yourName > Devices.
Removing a device from your account removes it as a trusted device for two-factor authentication, but will not sign out of any services or permanently remove it from the device list.
Workaround: To fully remove a device, click Remove From Account then sign out of iCloud in device Settings of the device you want to remove.
Known Issues
iForgot links may work intermittently.
Workaround: Please try again.
If you upgrade your Apple ID to use two-factor authentication, iTunes purchases on Mac and Windows and store purchases on Apple TV will require you to append a six-digit verification code to the end of your password on every purchase. The six-digit code will display automatically on your iOS 9 or OS X El Capitan devices, or can be sent to your trusted phone number via a text message or phone call.
If your Apple ID uses two-factor authentication, you may not be able to sign in to services that use Apple ID on iOS 9 and OS X El Capitan beta installations earlier than beta 3.
If you disable two-factor authentication and set a new password at iForgot.apple.com, the password requirements are not indicated so your password may not be accepted.
Workaround: Make sure your password meets these requirements:
Have at least one lowercase letter
Have at least one uppercase letter
Have at least one number
Your password must not contain more than two consecutive identical characters
Not be the same as the account name
Be at least 8 characters
Not be a common password
AVFoundation
Notes
The canUseNetworkResourcesForLiveStreamingWhilePaused property has been added to AVPlayerItem. The default value is NO for apps linked on or after iOS 9.0 or OS X 10.11, but YES for apps that were linked earlier.
To minimize power usage, set this property to NO if you do not need playback state to stay up to date while paused.
AVQueuePlayer now supports a mixture of file-based media and HTTP Live Streaming media in its queue. Prior to this, you had to ensure that all items in the queue were of the same type.
For apps linked against iOS 9 or later, the media interruption behavior for AV(Queue)Player has changed.
Before iOS 9, apps could interrupt other media-playing clients by associating or adding AVPlayerItem to AVPlayer or by modifying the time or date of the current AVPlayerItem (using the seekToTime: or seekToDate: methods). In iOS 9, these operations interrupt only when AVPlayer object’s playback rate is changed to a non-zero value through the rate property or play method.
Picture in Picture playback might stop and the Picture in Picture button might disappear when using AVPlayerViewController for video playback and replacing the underlying AVPlayer object’s current item usingreplaceCurrentItemWithPlayerItem:.
The AVPictureInPictureController interface and the cancelPictureInPicture method are deprecated.
Calendar
Fixed in Beta 5
Calendar may hang if you tap Ignore on a suggested event.
CarPlay
Fixed in Beta 5
The Home button may not always work.
Known Issue
The navigation bar in Maps can sometimes get into a state where it is inaccessible.
CBCentralManager
Note
The retrievePeripherals: and retrieveConnectedPeripherals methods were deprecated in iOS 7.0 and removed in iOS 9.0. Apps that use these methods will crash on launch or upon pairing an accessory.
Enterprise
Note
iOS 9 adds support for TLS v1.2 in 8021.X authentication. Authentication servers that support TLS v1.2 may require an update for compatibility. If you are using FreeRADIUS, update to version 2.2.7 or 3.0.8. If you are using Aruba ClearPass update to version 6.5.2. If you are using other Aruba products, update to ArubaOS 6.4.2.9.
Foundation
Notes
There is new Foundation API that can be used to detect if the device is in Low Power Mode. See the updated Energy Efficiency Guide for iOS Apps for details.
Horizontal location constraints should consistently reference either left/right or leading/trailing attributes. For apps linked against the iOS 9 SDK, NSLayoutConstraint will throw an exception if you attempt to create a constraint between a leading/trailing attribute and a left/right attribute.
HealthKit
Known Issue
In rare circumstances, it is possible for the health database to be deleted during an upgrade to a beta build.
Workaround: To make sure the health database is not lost, make an encrypted iTunes backup prior to installing this beta.
Although keeping the device unlocked for the duration of the upgrade process reduces the risk of the database being destroyed, it’s recommended that you create a backup so that you can recover the database if you encounter this issue.
Home Sharing
Fixed in Beta 5
If you have an empty music library, you will be unable to enable or disable Home Sharing in Music.
The Home Sharing option doesn't always appear in My Music.
Russian, Turkish, and Korean QuickType keyboards require iOS 9 beta 2 or later.
Fixed in Beta 5
If you use a complex passcode on an iPad, some panes in Settings will now show the keyboard.
Keychain
Note
iCloud Keychain will not sync passwords & credit cards with previous betas of iOS 9 and OS X El Capitan.
Fixed in Beta 5
You may not be able to accept a Suggested Password when creating a new account.
You may be unable to join an existing iCloud Keychain circle using iCloud Security Code and SMS Verification Code.
After changing your iCloud password, you may see an “iCloud Keychain Reset” prompt.
If you have two-step verification enabled on your AppleID and then change your iCloud Keychain or iCloud Security Code on a non-trusted device, you see a “Verification Failed” error.
If your iCloud account uses two-factor authentication, you will get a sign-in alert on all logged-in iOS 9 or OS X El Capitan devices whenever there is a change in the phone number in Settings > iCloud > Keychain > Advanced.
Mail
Known Issue
A Yahoo mail account may periodically display “Cannot get mail.”
Maps
Known Issue
If you use Siri to get driving, walking, or transit directions, you may see a failure with a dialog that says “Current Location not Available.”
Workaround: Toggle Wi-Fi and then try again. Alternatively, get directions in Maps directly without using Siri.
Messages
Fixed in Beta 5
When recording audio messages, the audio glyphs are not shown. This occurs in both quick reply and in the Messages app.
When you send an audio message, it may be difficult to begin playback.
Music
Note
When users plug in headphones or connect to Bluetooth or CarPlay in their car, their favorite music app appears on the lock screen or the car display.
For your app to be eligible for this, it must publish to Now Playing upon launch and consistently maintain a Now Playing state. A common practice upon launch is to continue playing the track from when the app was last exited.
Known Issues
The share sheet may not appear when sharing tracks from Apple Music.
The New tab may not load if you are not signed into Apple Music.
Networking
Note
When negotiating a TLS/SSL connection with Diffie-Hellman key exchange, iOS 9 requires a 1024-bit group or larger. These connections include:
Secure Web (HTTPS)
Enterprise Wi-Fi (802.1X)
Secure e-mail (IMAP, POP, SMTP)
Printing servers (IPPS)
Photo Booth
Fixed in Beta 5
Photos taken with Photo Booth are not saved.
ReplayKit
Known Issue
Playing a video while ReplayKit recording is ON will stop ongoing recording session and video will fail to play.
Safari
Fixed in Beta 5
Fixed a bug where calling reloadContentBlockerWithIdentifier:completionHandler: returned an error when running on a physical device.
Notes
When Done is tapped in a SFSafariViewController, it is automatically dismissed. You no longer need to dismiss it in the delegate method safariViewControllerDidFinish:.
“Find on Page” is now available both from the share sheet as well as in the Completions List.
Request Desktop Site has moved; it’s now in the Share sheet instead of Favorites.
Web Browser–to–Native App Handoff does not work with your app if the apple-app-site-association file isn’t correctly formatted and signed. For more information, see Handoff Programming Guide and Shared Web Credentials Reference.
Secure Transport
Note
DHE_RSA ciphersuites are now disabled by default in Secure Transport for TLS clients. This may cause failure to connect to TLS servers that only support DHE_RSA cipher suites. Applications that explicitly enable ciphersuites usingSSLSetEnabledCiphers() are not affected and will still use DHE_RSA ciphersuites if explicetely enabled.
Siri
Fixed in Beta 5
Siri cannot change Settings options.
Siri Eyes Free may not work.
You are unable to create, view, or edit notes using Siri.
Spotlight
Fixed in Beta 5
After upgrading to this beta, some contacts are not searchable in Spotlight.
UIKit
Notes
If initialized with a nilnibName value, UIViewController.nibName has always looked for a nib with a similar name as the view controller’s class, and defaulted to that value if loadView is not overridden.
Prior to iOS 9, subclasses of UIViewController that were written in Swift would require that their corresponding nib file name include the module prefix.
To improve flexibility in the event of refactoring, you can omit the module name from the nib file name in code that runs in iOS 9 beta 4 and later. UIViewController.nibName still prefers a name that contains the module prefix, but falls back to an unqualified name if a nib with the fully-qualified name is not found.
In iOS 9, when layoutIfNeeded is sent to a view and all of the following conditions are satisfied (which is not common), we apply fitting-size constraints (width/height = 0 at UILayoutPriorityFittingSizeLevel) instead of required size constraints (width/height required to match current size):
The receiver is not yet in the subtree of a view that hosts a layout engine, such as window, view controller view (unless you have set translatesAutoresizingMaskIntoConstraints to NO on that view—or created constraints that have one item in its subtree and one item outside it), table view cell content view, and so on.
The top-level view has a subview that is not a UIViewController-owned layout guide that also has translatesAutoresizingMaskIntoConstraints set to NO.
Under condition 1, we create a temporary layout engine from the top-level view and add all the constraints from the subtree to it. The problem is that we need to add some constraints that make the size of the top-level view unambiguous in the layout engine. The old behavior (prior to iOS 9) was that we would add constraints to restrict the size of the top-level view to its current bounds for any situation under condition 1. This really doesn’t make sense when you add conditions 2 and 3 and can result in unsatisfiable-constraints logging and broken layout.
So in iOS 9, for this special case only, we use fitting-size constraints instead.
This means that if you are sending layoutIfNeeded to a view under these conditions in iOS 9, you must be sure that either you have sufficient constraints to establish a size for the top-level view (which usually, though not always, is the receiver) or you must add temporary size constraints to the top-level view of layout size you desire before sending layoutIfNeeded, and remove them afterward.
For apps linked on iOS 9 or later, UITextView will now always correctly constrict its NSTextContainer to the fit inside the view when scrolling is disabled. Overflowing lines that lie outside of an NSTextContainer, even partially, are not rendered.
In previous iOS releases, the NSTextContainer sometimes was not constricted in size. This meant that logically overflowing lines were erroneously rendered. If you are seeing previously rendered lines at the end of your text view no longer rendered after linking your app against iOS 9, this behavior change is the likely cause. You can remedy this by making your UITextView larger, or perhaps by adjusting the bottom value of the text view's textContainerInset property.
Apps that subclass UIPrintPageRenderer or UIPrintFormatter to draw content for printing must be built with the iOS 9 SDK for the preview to display. The behavior of UIPrintPageRenderer has been updated to call drawPageAtIndex:inRect:multiple times with potentially different page sizes and margins. Various methods on UIPrintPageRenderer may be called from a non-main thread, but never from multiple threads concurrently.
UIPickerView and UIDatePicker are now resizable and adaptive—previously, these views would enforce a default size even if you attempted to resize them. These views also now default to a width of 320 points on all devices, instead of to the device width on iPhone.
Interfaces that rely on the old enforcement of the default size will likely look wrong when compiled for iOS 9. Any problems encountered can be resolved by fully constraining or sizing picker views to the desired size instead of relying on implicit behavior.
Known Issues
Instances of UIViewController classes that are defined in the UIKit library and are created with a nilnibBundle attempt to find their nib inside the UIKit framework instead of the app's main bundle.
Workaround: Pass [NSBundle mainBundle] for the nibBundle argument instead of nil.
Apps linked to versions of iOS earlier than iOS 8 may display incorrectly. Symptoms include cropping and displaying only in a small section of the screen.
Volume Purchase Program
Fixed in Beta 5
Apps that are distributed through VPP and are licensed to a device won't launch.
Watch App
Known Issue
Pairing iOS 9 beta 3 or 4 with watchOS 2 beta 1 or 2 requires you to sign out of your AppleID in Messages prior to pairing and to skip iCloud sign-in during pairing. Pairing with watchOS 2 beta 3 and watchOS 1 is not impacted.

iOS SDK 8.3 provides support for developing iOS apps. The SDK is packaged with a complete set of tools, compilers, and frameworks for creating apps for iOS and OS X. The tools include the Xcode IDE and the Instruments analysis tool, among many others.
With this software, you can develop apps for iPhone, iPad, or iPod touch running iOS 8. It now includes WatchKit, a framework for developing Apple Watch apps. You can test your apps using the included iOS Simulator.
iOS SDK 8.3 is included in Xcode 6.3, which requires a Mac computer running OS X v10.10 (Yosemite) or later.
This version of iOS is intended for installation only on devices registered with the Apple Developer Program. Attempting to install this version of iOS in an unauthorized manner could put your device in an unusable state.
iOS SDK 8.2 provides support for developing iOS apps. The SDK is packaged with a complete set of tools, compilers, and frameworks for creating apps for iOS and OS X. The tools include the Xcode IDE and the Instruments analysis tool, among many others.
With this software, you can develop apps for iPhone, iPad, or iPod touch running iOS 8. It now includes WatchKit, a framework for developing Apple Watch apps. You can test your apps using the included iOS Simulator.
iOS SDK 8.2 requires a Mac computer running OS X v10.9.3 (Mavericks) or later.
This version of iOS is intended for installation only on devices registered with the Apple Developer Program. Attempting to install this version of iOS in an unauthorized manner could put your device in an unusable state.
The Thai system font has increased in size to improve readability. This will cause clipping in many places in your UI if you don’t take appropriate action:
Use UILabel as much as possible. If you use Interface Builder, make sure that Clip Subviews is not checked. UIKit will grow the clipping region as necessary to not clip text.
Use Dynamic Type. This will ensure that you do not have overlapping glyphs in multiline labels or text fields.
If you can’t do 1 and 2 because you implement your own views, you must implement measures not to clip. You can use CoreText to figure out the appropriate clipping region for a line of text by calling:
To avoid overlapping glyphs in multiline text elements, adjust the line height. An additional 30% is recommended.
This measure will also help your app perform better in other languages, including Arabic, Hindi, and Vietnamese.
iCloud
Note
Mail handoff and AirDrop may stop working after changing your iCloud password at appleid.apple.com.
Workaround: Sign out and back into iCloud on the device.
iCloud Drive
Note
URLForUbiquityContainerIdentifier: might return nil when running your application in Xcode. If so, open System Preferences, navigate to iCloud > iCloud Drive, and enable Xcode.
Messages
Fixed in Beta 3
Your device may get into a state where tapping into Messages conversations can take a long time.
Notification Center
Note
The schedule and intended use of widgetPerformUpdateWithCompletionHandler: is intended as a convenient home for all data/model update logic. If implemented, the system will call at opportune times for the widget to update its state, both when Notification Center is visible, as well as in the background. An implementation is required to enable background updates. It’s expected that the widget will perform the work to update asynchronously and off the main thread as much as possible. Widgets should call the argument block when the work is complete, passing the appropriate NCUpdateResult. Widgets should NOT block returning from viewWillAppear: on the results of this operation. Instead, widgets should load cached state in viewWillAppear: in order to match the state of the view from the last viewWillDisappear:, then transition smoothly to the new data when it arrives.
NSURLSession
Note
The NSURLSessionTask class provides a new “priority” property with three associated constants: NSURLSessionTaskPriorityDefault, NSURLSessionTaskPriorityLow, andNSURLSessionTaskPriorityHigh. NSURLSessionTask priorities can be used to specify how multiple requests and responses to the same host should be prioritized. Note that the priority is a hint and not a strict guarantee of NSURLSessionTask performance.
For complete usage details of NSURLSessionTask priorities, refer to the NSURLSession.h header file, which is provided by the Foundation framework.
Phone
Note
To activate Wi-Fi Calling functionality for T-Mobile (U.S. only), follow these steps:
Go to Settings > Phone > Wi-Fi Calling.
Toggle the Wi-Fi Calling switch to ON.
If the carrier does not have the user’s registered emergency address, you will be asked to add it before the feature is activated.
Photos
Notes
Maintain a backup of your photo library before enabling and while using iCloud Photo Library beta by:
Importing to your Mac using iPhoto
Importing to your Mac using Image Capture
iCloud Photo Library beta will not download photos and videos that were synced to your device from iTunes. Any photos and videos synced to your device from iTunes will be removed when you enable iCloud Photo Library beta.
iPhoto for iOS will not launch on iOS 8 beta. Launching Photos.app will migrate your iPhoto edits to the iOS 8 Photo Library. Make sure your iPhoto for iOS data is included in your device backup.
The ability to automatically optimize device space is enabled for all accounts larger than 5GB.
When using iCloud Family Sharing, both iCloud Photo Sharing and My Photo Stream are enabled.

WatchKit
Notes
The WKInterfaceMap API has changed. Specifically, setMapRect: and setCoordinateRegion: have been replaced by setVisibleMapRect: and setRegion: respectively.
The WKInterfaceController method initWithContext: has been deprecated. Please use awakeWithContext: instead. The designated initializer for WKInterfaceController is now init.
Rows in a WKInterfaceTable now have a default appearance. This appearance can be overridden by specifying the values for background color, margin, corner radius, and height for the row in Interface Builder.
Fixed in Beta 3
In iOS Simulator, the Emoji button should now be visible, regardless of the selected input mode.
The WKInterfaceController method openParentApplication:reply: now launches the containing app in the background when the iPhone (or iOS Simulator) is unlocked or locked.
The WKInterfaceController method presentTextInputControllerWithSuggestions:completion: is now fully supported in iOS Simulator.
Known Issue
Inserting, deleting, or updating rows of a WKInterfaceTable may cause the table to temporarily size incorrectly. Scrolling your interface controller should restore the table to the proper size.
Wi-Fi Calling (T-Mobile US only)
Note
The carrier name in the status bar will show “T-Mobile Wi-Fi” when the device is able to make and receive Wi-Fi calls.
This article summarizes the key developer-related features introduced in iOS 8, which runs on currently shipping iOS devices. The article also lists the documents that describe new features in more detail.
iOS 8 lets you extend select areas of the system by supplying an app extension, which is code that enables custom functionality within the context of a user task. For example, you might supply an app extension that helps users post content to your social sharing website. After users install and enable this extension, they can choose it when they tap the Share button in their current app. Your custom sharing extension provides the code that accepts, validates, and posts the user’s content. The system lists the extension in the sharing menu and instantiates it when the user chooses it.
In Xcode, you create an app extension by adding a preconfigured app extension target to an app. After a user installs an app that contains an extension, user enables the extension in the Settings app. When the user is running other apps, the system makes the enabled extension available in the appropriate system UI, such as the Share menu.
iOS supports app extensions for the following areas, which are known as extension points:
Share. Share content with social websites or other entities.
Action. Perform a simple task with the selected content.
Today. Provide a quick update or enable a brief task in the Today view of Notification Center.
Photo editing. Perform edits to a photo or video within the Photos app.
Storage provider. Provide a document storage location that can be accessed by other apps. Apps that use a document picker view controller can open files managed by the Storage Provider or move files into the Storage Provider.
Custom keyboard. Provide a custom keyboard that the user can choose in place of the system keyboard for all apps on the device.
Each extension point defines appropriate APIs for its purposes. When you use an app extension template to begin development, you get a default target that contains method stubs and property list settings defined by the extension point you chose.
Your app can now use Touch ID to authenticate the user. Some apps may need to secure access to all of their content, while others might need to secure certain pieces of information or options. In either case, you can require the user to authenticate before proceeding. Use the Local Authentication Framework (LocalAuthentication.framework) to display an alert to the user with an application-specified reason for why the user is authenticating. When your app gets a reply, it can react based on whether the user was able to successfully authenticate.
The PassKit framework adds support for payment passes and payment requests. Payment requests let users securely provide you with their payment and contact information to pay for physical goods and services. Payment passes are added to Passbook by payment networks, such as credit card issuers and banks, and let the user select their account on that payment network to fund payments.
Take better photos in your app, provide new editing capabilities to the Photos app, and create new, more efficient workflows that access the user’s photo and video assets.
Photos Framework
The Photos framework (Photos.framework) provides new APIs for working with photo and video assets, including iCloud Photos assets, that are managed by the Photos app. This framework is a more capable alternative to the Assets Library framework. Key features include a thread-safe architecture for fetching and caching thumbnails and full-sized assets, requesting changes to assets, observing changes made by other apps, and resumable editing of asset content.
Use the related Photos UI framework (PhotosUI.framework) to create app extensions for editing image and video assets in the Photos app. For more information, see App Extension Programming Guide.
Manual Camera Controls
The AV Foundation framework (AVFoundation.framework) makes it easier than ever to take great photos. Your app can take direct control over the camera focus, white balance, and exposure settings. In addition, your app can use bracketed exposure captures to automatically capture images with different exposure settings.
A new property (autoFocusSystem) can be used to determine how the camera performs auto focusing.
Games
Technology improvements in iOS 8 make it easier than ever to implement your game’s graphics and audio features. Take advantage of high-level frameworks for ease-of-development, or use new low-level enhancements to harness the power of the GPU.
Metal
Metal provides extremely low-overhead access to the A7 and A8 GPUs, enabling extremely high performance for your sophisticated graphics rendering and computational tasks. Metal eliminates many performance bottlenecks—such as costly state validation—that are found in traditional graphics APIs. Metal is explicitly designed to move all expensive state translation and compilation operations out of the critical path of your most performance sensitive rendering code. Metal provides precompiled shaders, state objects, and explicit command scheduling to ensure your application achieves the highest possible performance and efficiency for your GPU graphics and compute tasks. This design philosophy extends to the tools used to build your app. When your app is built, Xcode compiles Metal shaders in the project into a default library, eliminating most of the runtime cost of preparing those shaders.
Graphics, compute, and blit commands are designed to be used together seamlessly and efficiently. Metal is specifically designed to exploit modern architectural considerations, such as multiprocessing and shared memory, to make it easy to parallelize the creation of GPU commands.
With Metal, you have a streamlined API, a unified graphics and compute shading language, and Xcode-based tools, so you don’t need to learn multiple frameworks, languages, and tools to take full advantage of the GPU in your game or app.
SceneKit is an Objective-C framework for building simple games and rich app user interfaces with 3D graphics, combining a high-performance rendering engine with a high-level, descriptive API. SceneKit has been available since OS X v10.8 and is now available in iOS for the first time. Lower-level APIs (such as OpenGL ES) require you to implement the rendering algorithms that display a scene in precise detail. By contrast, SceneKit lets you describe your scene in terms of its content—geometry, materials, lights, and cameras—then animate it by describing changes to those objects.
SceneKit’s 3D physics engine enlivens your app or game by simulating gravity, forces, rigid body collisions, and joints. Add high-level behaviors that make it easy to use wheeled vehicles such as cars in a scene, and add physics fields that apply radial gravity, electromagnetism, or turbulence to objects within an area of effect.
Use OpenGL ES to render additional content into a scene, or provide GLSL shaders that replace or augment SceneKit’s rendering. You can also add shader-based postprocessing techniques to SceneKit’s rendering, such as color grading or screen space ambient occlusion.
The SpriteKit framework (SpriteKit.framework) adds new features to make it easier to support advanced game effects. These features include support for custom OpenGL ES shaders and lighting, integration with SceneKit, and advanced new physics effects and animations. For example, you can create physics fields to simulate gravity, drag, and electromagnetic forces using the SKFieldNode class. You can easily create physics bodies with per-pixel collision masks. And it is easier than ever to pin a physics body to its parent, even if its parent does not have a physics body of its own. These new physics features make complex simulations much easier to implement.
Use constraints to modify the effects of physics and animations on the content of your scene—for example, you can make one node always point toward another node regardless of where the two nodes move.
Xcode 6 also incorporates new shader and scene editors that save you time as you create your game. Create a scene’s contents, specifying which nodes appear in the scene and characteristics of those nodes, including physics effects. The scene is then serialized to a file that your game can easily load.
AVFoundation framework (AVFoundation.framework) adds support for a broad cross-section of audio functionality at a higher level of abstraction than Core Audio. These new audio capabilities are available on both OS X and iOS and include automatic access to audio input and output hardware, audio recording and playback, and audio file parsing and conversion. You also gain access to audio units for generating special effects and filters, pitch and playback speed management, stereo and 3D audio environments, and MIDI instruments.
The APPLE_color_buffer_packed_float extension builds on APPLE_texture_packed_float so that the new texture formats can be used by a framebuffer object. This means that an app can render into a framebuffer that uses one of these formats.
HealthKit Framework
HealthKit (HealthKit.framework) is a new framework for managing a user’s health-related information. With the proliferation of apps and devices for tracking health and fitness information, it's difficult for users to get a clear picture of how they are doing. HealthKit makes it easy for apps to share health-related information, whether that information comes from devices connected to an iOS device or is entered manually by the user. The user’s health information is stored in a centralized and secure location. The user can then see all of that data displayed in the Health app.
When your app implements support for HealthKit, it gets access to health-related information for the user and can provide information about the user, without needing to implement support for specific fitness-tracking devices. The user decides which data should be shared with your app. Once data is shared with your app, your app can register to be notified when that data changes; you have fine-grained control over when your app is notified. For example, request that your app be notified whenever users takes their blood pressure, or be notified only when a measurement shows that the user’s blood pressure is too high.
HomeKit Framework
HomeKit (HomeKit.framework) is a new framework for communicating with and controlling connected devices in a user’s home. New devices for the home are offering more connectivity and a better user experience. HomeKit provides a standardized way to communicate with those devices.
Your app can use HomeKit to communicate with devices that users have in their homes. Using your app, users can discover devices in their home and configure them. They can also create actions to control those devices. The user can group actions together and trigger them using Siri. Once a configuration is created, users can invite other people to share access to it. For example, a user might temporarily offer access to a house guest.
Use the HomeKit Accessory Simulator to test the communication of your HomeKit app with a device.
iCloud includes some changes that affect the behavior of existing apps and that affect users of those apps.
Document-Related Data Migration
The iCloud infrastructure is more robust and reliable when documents and data are transferred between user devices and the server. When a user installs iOS 8 and logs into the device with an iCloud account, the iCloud server performs a one-time migration of the documents and data in that user’s account. This migration involves copying the documents and data to a new version of the app’s container directory. The new container is accessible only to devices running iOS 8 or OS X v10.10. Devices running older operating systems can continue to access to the original container, but changes made in that container do not appear in the new container and changes made in the new container do not appear in the original container.
CloudKit
CloudKit (CloudKit.framework) is a conduit for moving data between your app and iCloud. Unlike other iCloud technologies where data transfers happen transparently, CloudKit gives you control over when transfers occur. You can use CloudKit to manage all types of data.
Apps that use CloudKit directly can store data in a repository that is shared by all users. This public repository is tied to the app itself and is available even on devices without a registered iCloud account. As the app developer, you can manage the data in this container directly and see any changes made by users through the CloudKit dashboard.
The document picker view controller (UIDocumentPickerViewController) grants users access to files outside your application’s sandbox. It is a simple mechanism for sharing documents between apps. It also enables more complex workflows, because users can edit a single document with multiple apps.
The document picker lets you access files from a number of document providers. For example, the iCloud document provider grants access to documents stored inside another app’s iCloud container. Third-party developers can provide additional document providers by using the Storage Provider extension.
Handoff is a feature in OS X and iOS that extends the user experience of continuity across devices. Handoff enables users to begin an activity on one device, then switch to another device and resume the same activity on the other device. For example, a user who is browsing a long article in Safari moves to an iOS device that's signed in to the same Apple ID, and the same webpage automatically opens in Safari on iOS, with the same scroll position as on the original device. Handoff makes this experience as seamless as possible.
To participate in Handoff, an app adopts a small API in Foundation. Each ongoing activity in an app is represented by a user activity object that contains the data needed to resume an activity on another device. When the user chooses to resume that activity, the object is sent to the resuming device. Each user activity object has a delegate object that is invoked to refresh the activity state at opportune times, such as just before the user activity object is sent between devices.
If continuing an activity requires more data than is easily transferred by the user activity object, the resuming app has the option to open a stream to the originating app. Document-based apps automatically support activity continuation for users working with iCloud-based documents.
Apps linked against iOS 8 and later should be prepared to support the larger screen size of iPhone 6 and iPhone 6 Plus. On the iPhone 6 Plus, apps should also be prepared to support a new screen scale. In particular, apps that support OpenGL ES and Metal can also choose to size their rendering CAEAGLLayeror CAMetalLayer to get the best possible performance on the iPhone 6 Plus.
To let the system know that your app supports the iPhone 6 screen sizes, include a storyboard launch screen file in your app’s bundle. At runtime, the system looks for a storyboard launch screen file. If such an file is present, the system assumes that your app supports the iPhone 6 and 6 Plus explicitly and runs it in fullscreen mode. If such an image is not present, the system reports a smaller screen size (either 320 by 480 points or 320 by 568 points) so that your app’s screen-based calculations continue to be correct. The contents are then scaled to fit the larger screen.
iOS 8 adds new features that make dealing with screen size and orientation much more versatile. It is easier than ever to create a single interface for your app that works well on both iPad and iPhone, adjusting to orientation changes and different screen sizes as needed. Using size classes, you can retrieve general information about the size of a device in its current orientation. You can use this information to make initial assumptions about which content should be displayed and how those interface elements are related to each other. Then, use Auto Layout to resize and reposition these elements to fit the actual size of the area provided. Xcode 6 uses size classes and autolayout to create storyboards that adapt automatically to size class changes and different screen sizes.
Traits Describe the Size Class and Scale of an Interface
Size classes are traits assigned to a user interface element, such as a screen or a view. There are two types of size classes in iOS 8: regular and compact. A regular size class denotes either a large amount of screen space, such as on an iPad, or a commonly adopted paradigm that provides the illusion of a large amount of screen space, such as scrolling on an iPhone. Every device is defined by a size class, both vertically and horizontally.
Figure 1 and Figure 2 show the native size classes for the iPad. With the amount of screen space available, the iPad has a regular size class in the vertical and horizontal directions in both portrait and landscape orientations.
Figure 1 iPad size classes in portraitFigure 2 iPad size classes in landscape
The size classes for iPhones differ based on the kind of device and its orientation. In portrait, the screen has a compact size class horizontally and a regular size class vertically. This corresponds to the common usage paradigm of scrolling vertically for more information. When iPhones are in landscape, their size classes vary. Most iPhones have a compact size class both horizontally and vertically, as shown in Figure 3 and Figure 4. The iPhone 6 Plus has a screen large enough to support regular width in landscape mode, as shown in Figure 5.
Figure 3 iPhone size classes in portraitFigure 4 iPhone size classes in landscapeFigure 5 iPhone 6 Plus classes in landscape
You can change the size classes associated with a view. This flexibility is especially useful when a smaller view is contained within a larger view. Use the default size classes to arrange the user interface of the larger view and arrange information in the subview based on whatever size classes you feel is most appropriate to that subview.
To support size classes, the following classes are new or modified:
The UITraitCollection class is used to describe a collection of traits assigned to an object. Traits specify the size class, display scale, and idiom for a particular object. Classes that support the UITraitEnvironment protocol (such as UIScreen, UIViewController and UIView) own a trait collection. You can retrieve an object’s trait collection and perform actions when those traits change.
The UIImageAsset class is used to group like images together based on their traits. Combine similar images with slightly different traits into a single asset and then automatically retrieve the correct image for a particular trait collection from the image asset. The UIImage class has been modified to work with image assets.
Classes that support the UIAppearance protocol can customize an object’s appearance based on its trait collection.
The UIViewController class adds the ability to retrieve the trait collection for a child view. You can also lay out the view by changing the size class change through the viewWillTransitionToSize:withTransitionCoordinator: method.
Xcode 6 supports unified storyboards. A storyboard can add or remove views and layout constraints based on the size class that the view controller is displayed in. Rather than maintaining two separate (but similar) storyboards, you can make a single storyboard for multiple size classes. First, design your storyboard with a common interface and then customize it for different size classes, adapting the interface to the strengths of each form factor. Use Xcode 6 to test your app in a variety of size classes and screen sizes to make sure that your interface adapts to the new sizes properly.
Supporting New Screen Scales
The iPhone 6 Plus uses a new Retina HD display with a very high DPI screen. To support this resolution, iPhone 6 Plus creates a UIScreen object with a screen size of 414 x 736 points and a screen scale of 3.0 (1242 x 2208 pixels). After the contents of the screen are rendered, UIKit samples this content down to fit the actual screen dimensions of 1080 x 1920. To support this rendering behavior, include new artwork designed for the new 3x screen scale. In Xcode 6, asset catalogs can include images at 1x, 2x, and 3x sizes; simply add the new image assets and iOS will choose the correct assets when running on an iPhone 6 Plus. The image loading behavior in iOS also recognizes an @3x suffix.
In a graphics app that uses Metal or OpenGL ES, content can be easily rendered at the precise dimensions of the display without requiring an additional sampling stage. This is critical in high-performance 3D apps that perform many calculations for each rendered pixel. Instead, create buffers to render into that are the exact resolution of the display.
A UIScreen object provides a new property (nativeScale) that provides the native screen scale factor for the screen. When the nativeScale property has the same value as the screen’sscale property, then the rendered pixel dimensions are the same as the screen’s native pixel dimensions. When the two values differ, then you can expect the contents to be sampled before they are displayed.
If you are writing an OpenGL ES app, a GLKView object automatically creates its renderbuffer objects based on the view’s size and the value of itscontentScaleFactor property. After the view has been added to a window, set the view’s contentScaleFactor to the value stored in the screen’snativeScale property, as shown in Listing 1.
Listing 1 Supporting native scale in a GLKView object
In a Metal app, your own view class should have code similar to the code found in Listing 1. In addition, whenever your view’s size changes, and prior to asking the Metal layer for a new drawable, calculate and set the metal layer’s drawableSize property as shown in Listing 2. (An OpenGL ES app that is creating its own renderbuffers would use a similar calculation.)
Listing 2 Adjusting the size of a Metal layer to match the native screen scale
CGSize drawableSize = self.bounds.size;
drawableSize.width *= self.contentScaleFactor;
drawableSize.height *= self.contentScaleFactor;
metalLayer.drawableSize = drawableSize;
See MetalBasic3D for a working example. The Xcode templates for OpenGL ES and Metal also demonstrate these same techniques.
Additional Framework Changes
In addition to the major changes described above, iOS 8 includes other improvements.
API Modernization
Many frameworks on iOS have adopted small interface changes that take advantage of modern Objective-C syntax:
Getter and setter methods are replaced by properties in most classes. Code using the existing getter and setter methods continues to work with this change.
Initialization methods are updated to have a return value of instancetype instead of id.
Designated initializers are declared as such where appropriate.
In most cases, these changes do not require any additional work in your own app. However, you may also want to implement these changes in your own Objective-C code. In particular, you may want to modernize your Objective-C code for the best experience when interoperating with Swift code.
The AV Foundation framework (AVFoundation.framework) enables you to capture metadata over time while shooting video. Arbitrary types of metadata can be embedded with a video recording at various points in time. For example, you might record the current physical location in a video created by a moving camera device.
The AVKit framework (AVKit.framework) previously introduced on OS X is available on iOS. Use it instead of Media Player framework when you need to display a video.
CoreAudioKit Framework
The new CoreAudioKit framework simplifies the effort required to create user interfaces for apps that take advantage of inter-app audio.
Core Image Framework
The Core Image framework (CoreImage.framework) has the following changes:
You can create custom image kernels in iOS.
Core image detectors can detect rectangles and QR codes in an image.
The Core Location framework (CoreLocation.framework) has the following changes:
You can determine which floor the device is on, if the device is in a multistory building.
The visit service provides an alternative to the significant location change service for apps that need location information about interesting places visited by the user.
Core Motion provides two new classes (CMAltimeter and CMAltitudeData) which allow you to access the barometer on the iPhone 6 and iPhone 6 Plus. On these two devices, you can also use a CMMotionActivity object to determine whether the user is on a bicycle.
Foundation Framework
The Foundation framework (Foundation.framework) includes the following enhancements:
The NSFileVersion class provides access to past versions of iCloud documents. These versions are stored in iCloud, but can be downloaded on request.
The NSURL class supports storing document thumbnails as metadata.
The NSMetadataQuery class can search for external iCloud documents that your app has opened.
Game Controller Framework
The Game Controller framework (GameController.framework) has the following changes:
If the controller is attached to a device, you can now receive device motion data directly from the Game Controller framework.
If you are working with button inputs and do not care about pressure sensitivity, a new handler can call your game only when the button’s pressed state changes.
GameKit Framework
The GameKit framework (GameKit.framework) has the following changes:
Features that were added in iOS 7 are available on OS X 10.10, making it easier to use these features in a cross-platform game.
The new GKSavedGame class and new methods in GKLocalPlayer make it easy to save and restore a user’s progress. The data is stored on iCloud; GameKit does the necessary work to synchronize the files between the device and iCloud.
Methods and properties that use player identifier strings are now deprecated. Instead, use GKPlayer objects to identify players. Replacement properties and methods have been added that take GKPlayer objects.
iAd Framework
The iAd framework (iAd.framework) adds the following new features:
If you are using AV Kit to play a video, you can play preroll advertisements before the video is played.
You can look up more information about the the effectiveness of advertisements for your app.
SKSpriteNode objects can provide lighting information so that SpriteKit automatically generates lighting effects and shadows. Add SKLightNodeobjects to the scene to specify the lights, and then customize the properties on these lights and any sprites to determine how the scene is lit.
The SKFieldNode class provides physics special effects you can apply to a scene. For example, create magnetic fields, add drag effects, or even generate randomized motion. All effects are constrained to a specific region of the scene, and you can carefully tune both the effect’s strength and how quickly the effect is weakened by distance. Field nodes make it easy to drop in an effect without having to search the entire list of physics bodies and apply forces to them.
A new SK3DNode class is used to integrate a SceneKit scene into your game as a sprite. Each time that SpriteKit renders your scene, it renders the 3D scene node first to generate a texture, then uses that texture to render a sprite in SpriteKit. Creating 3D sprites can help you avoid creating dozens of frames of animation to produce an effect.
New actions have been added, including support for inverse kinematic animations.
A new system of constraints has been added to scene processing. SpriteKit applies constraints after physics is simulated, and you use them to specify a set of rules for how a node is positioned and oriented. For example, you can use a constraint to specify that a particular node in the scene always points at another node in the scene. Constraints make it easier to implement rendering rules in your game without having to tweak the scene manually in your event loop.
A scene can implement all of the run-loop stages in a delegate instead of subclassing the SKScene class. Using a delegate often means that you can avoid needing to subclass the SKScene class.
The SKView class provides more debugging information. You can also provide more performance hints to the renderer.
You can create normal map textures for use in lighting and physics calculations (or inside your own custom shaders). Use the new SKMutableTextureclass when you need to create textures whose contents are dynamically updated.
You can generate texture atlases dynamically at runtime from a collection of textures.
Xcode 6 also incorporates many new SpriteKit editors. Create or edit the contents of scenes directly, specifying the nodes that appear in the scene as well as their physics bodies and other characteristics. The scene is serialized to a file and can be loaded directly by your game. The editors save you time because often you don’t need to implement your own custom editors to create your game’s assets.
The UIKit framework (UIKit.framework) includes the following enhancements:
Apps that use local or push notifications must explicitly register the types of alerts that they display to users by using a UIUserNotificationSettingsobject. This registration process is separate from the process for registering remote notifications, and users must grant permission to deliver notifications through the requested options.
Local and push notifications can include custom actions as part of an alert. Custom actions appear as buttons in the alert. When tapped, your app is notified and asked to perform the corresponding action. Local notifications can also be triggered by interactions with Core Location regions.
Collection views support dynamically changing the size of cells. Typically, you use this support to accommodate changes to the preferred text size, but you can adapt it for other scenarios too. Collection views also support more options for invalidating different portions of the layout and thereby improving performance.
The UISearchController class replaces the UISearchDisplayController class for managing the display of search-related interfaces.
The UISplitViewController class is now supported on iPhone as well as iPad. The class adjusts its presented interface to adapt to the available space. The class also changes the way it shows and hides the primary view controller, giving you more control over how to display the split view interface.
The UINavigationController class has new options for changing the size of the navigation bar or hiding it altogether.
The new UIVisualEffect class enables you to integrate custom blur effects into your view hierarchies.
The new UIPresentationController class lets you separate the content of your view controllers from the chrome used to display them.
The new UIPopoverPresentationController class handles the presentation of content in a popover. The existing UIPopoverController class uses the popover presentation controller to show popovers on the screen.
The new UIPrinterPickerController class offers a view controller-based way to display a list of printers and to select one to use during printing. Printers are represented by instances of the new UIPrinter class.
The Video Toolbox framework (VideoToolbox.framework) includes direct access to hardware video encoding and decoding.
Webkit Framework
A number of new classes have been added to make it easier to create high-performance native apps that utilize web content. See WebKit Framework Reference.
Deprecated APIs
The following APIs are deprecated:
The UIApplication methods and properties for registering notifications. Use the new API instead.
The UIViewController methods and properties for interface orientation. Traits and size classes replace them, as described in Unified Storyboards for Universal Apps. There are other smaller changes to UIKit API to support size classes; often older interfaces that used specific device idioms have been replaced.
iOS SDK 8.0 provides support for developing iOS apps. It is packaged with a complete set of Xcode tools, compilers, and frameworks for creating apps for iOS and OS X. These tools include the Xcode IDE and the Instruments analysis tool, among many others.
With this software you can develop apps for iPhone, iPad, or iPod touch running iOS 8. You can also test your apps using the included iOS Simulator, which supports iOS 8. iOS SDK 8.0 requires a Mac computer running OS X v10.9.3 (Mavericks) or later.
This version of iOS is intended for installation only on devices registered with the Apple Developer Program. Attempting to install this version of iOS in an unauthorized manner could put your device in an unusable state.
A restoration of an iCloud backup onto the same device the backup was taken from may not work properly. As a result, some apps may crash.
Known Issues
Encrypted backups to iTunes fail.
iOS 7 iCloud backups restored to an iOS 8 beta device may not properly restore photos.
CarPlay
Fixed in beta 5
The Now Playing screen is missing the Back button in the top-left corner.
CloudKit
Fixed in beta 5
Clients sending multiple simultaneous record update requests to the same zone in the private database may encounter CKErrorZoneBusy errors.
Workaround: Clients should send update requests for a given zone one at a time. In addition, they should handle CKErrorZoneBusy errors by retrying with an exponential backoff.
Contacts
Note
The Address Book UI people picker has been changed for iOS 8. A new mode with new API has been added where the app does not need access to the user’s contacts and the user will not be prompted for access. A temporary copy of the selected person is returned to the app. See ABPeoplePickerNavigationController.h for more details.
As of iOS 8 beta 2, you must use the new mode. The old mode has been deprecated.
Now that the Share My Location feature is integrated into Messages, Find My Friends only supports the Apple ID configured in Settings > iCloud.
Fonts
Note
The Thai system font has increased in size to improve readability. This will cause clipping in many places in your UI if you don’t take appropriate action:
Use UILabel as much as possible. If you use Interface Builder, make sure that Clip Subviews is not checked. UIKit will grow the clipping region as necessary to not clip text.
Use Dynamic Type. This will ensure that you do not have overlapping glyphs in multiline labels or text fields.
If you can’t do 1 and 2 because you implement your own views, you must implement measures not to clip. You can use CoreText to figure out the appropriate clipping region for a line of text by calling:
To avoid overlapping glyphs in multiline text elements, adjust the line height. An additional 30% is recommended.
This measure will also help your app perform better in other languages, including Arabic, Hindi, and Vietnamese.
Handoff
Note
Handoff is incompatible between devices using this beta and the prior beta. You should test Handoff with the most recent beta software because it is not backward-compatible with previous betas.
HealthKit
Notes
Spirometry data types are now available in HealthKit.
Any blood type that was set in Medical ID prior to beta 3 will be cleared.
The pairing UI for BTLE health devices has been removed from HealthKit and is now available in Settings > Bluetooth.
The HKWorkout API is now available to store workouts.
HKQuantityTypeIdentifierGalvanicSkinResponse has been renamed HKQuantityTypeIdentifierElectrodermalActivity.
The following HKObjectType identifiers have been removed:
HKQuantityTypeIdentifierRRInterval
HKQuantityTypeIdentifierHeatFlux
HKCorrelationTypeIdentifierHeartRateReading
HomeKit
Note
After upgrading to beta 5, you need to reset your home configuration in Settings > Privacy > HomeKit > Reset Home Configuration.
You must sign into iCloud and enable Keychain sync to use HomeKit with this seed.
Known Issue
Siri may not immediately recognize HomeKit data changes.
Workaround: To trigger an update to Siri, edit other data used by Siri such as a contact or the name of a Reminders list.
iAd
Fixed in beta 5
iAd videos may not play in NPR HLS station.
iCloud Drive
Notes
iCloud Documents & Data created with iOS 8 Beta will be deleted from the servers at some point during this beta period. Information downloaded and not evicted from the device will remain on device and will re-sync after the data wipe occurs.
Document storage containers created using the UIDocument class in iOS 7 are not yet available for use with iCloud Documents through Xcode 6 beta or in the Certificates, Identifiers & Profiles section of Member Center. These containers will be migrated later and associated with your existing App IDs.
URLForUbiquityContainerIdentifier: might return nil when running your application in Xcode. If so, open System Preferences, navigate to iCloud > iCloud Drive, and enable Xcode.
Migrating to iCloud Drive will disable Documents & Data syncing for your iCloud account on iOS 7 and earlier devices, as well as OS X Mavericks and earlier Macs.
iCloud Keychain
Fixed in beta 5
Initial sync does not work if the approving device is locked when the approval occurs.
Using the recovery option can leave you in a state where new items added to the keychain do not sync.
Known Issue
Upon logging into a device with the iCloud 8 beta, other devices in your keychain circle may have their access to the circle revoked.
Workaround: Enable iCloud Keychain Sync on your other devices again.
iTunes Sync
Known Issue
Apps do not sync from a device to iTunes.
Keyboards
Fixed in beta 5
If you turn off predictive text in one app and then turn it back on in another, it may not actually be reactivated.
Caps Lock may be unexpectedly enabled in text input fields.
Localization
Fixed in beta 5
The following have English strings that are now properly localized in other languages:
VoiceOverTouch
Sharing
ManagedConfiguration
AirPortAssistant
MapKit
SpringboardUIServices
AccessibilityBundles
Music
Maps
Known Issue
When viewed in the Simulator, the "Hybrid" view in Maps and MapKit apps does not show all of the tiles.
Metal and OpenGL
Fixed in beta 5
Shadow samplers are broken when using linear filtering.
Workaround: For OpenGL, set GL_TEXTURE_MIN_FILTER and GL_TEXTURE_MAG_FILTER to GL_NEAREST. For Metal, set the mag_filter and min_filter sampler properties to nearest in the shader source.
Music
Fixed in beta 5
The Music app may stop responding when downloading an album.
Notification Center
Note
The schedule and intended use of widgetPerformUpdateWithCompletionHandler: is intended as a convenient home for all data/model update logic. If implemented, the system will call at opportune times for the widget to update its state, both when Notification Center is visible, as well as in the background. An implementation is required to enable background updates. It’s expected that the widget will perform the work to update asynchronously and off the main thread as much as possible. Widgets should call the argument block when the work is complete, passing the appropriate NCUpdateResult. Widgets should NOT block returning from viewWillAppear: on the results of this operation. Instead, widgets should load cached state in viewWillAppear: in order to match the state of the view from the last viewWillDisappear:, then transition smoothly to the new data when it arrives.
NSURLSession
Note
Beginning in iOS 8 beta 2, the NSURLSessionTask class provides a new “priority” property with three associated constants: NSURLSessionTaskPriorityDefault, NSURLSessionTaskPriorityLow, and NSURLSessionTaskPriorityHigh. NSURLSessionTask priorities can be used to specify how multiple requests and responses to the same host should be prioritized. Note that the priority is a hint and not a strict guarantee of NSURLSessionTask performance.
For complete usage details of NSURLSessionTask priorities, refer to the NSURLSession.h header file, which is provided by the Foundation framework.
Phone
Note
To activate Wi-Fi Calling functionality for T-Mobile (U.S. only), follow these steps:
Go to Settings > Phone > Wi-Fi Calling.
Toggle the Wi-Fi Calling switch to ON.
If the carrier does not have the user’s registered emergency address, you will be asked to add it before the feature is activated.
Photos
Notes
iCloud Photo Library requires beta 3 or later.
Back up your photo libraries before enabling iCloud Photo Library by:
Importing to your Mac using iPhoto
Importing to your Mac using Image Capture
Enabling iCloud Photo Library will not add photos/videos that have been synced with iTunes to the cloud.
iPhoto for iOS will not launch on iOS 8 Beta. Launching Photos.app will migrate your iPhoto edits to the iOS 8 Photo Library. Make sure your iPhoto for iOS data is included in your device backup.
Known Issues
The ability to automatically optimize device space is not enabled in this beta.
When using iCloud Family, both iCloud Photos and My Photostream are enabled.
After restore from iCloud backup, modified photos may show unmodified thumbnails.
If you reach your iCloud quota, there is no way to add or delete data within the Photos app.
Quicklook
Known Issue
PDF files may not display in some applications.
Safari
Notes
Safari now blocks ads from automatically redirecting to the App Store without user interaction. If you still see the previous behavior, or find legitimate redirection to the App Store to be broken in some way, please file a bug.
You can now quickly add a site to Shared Links or save a bookmark by tapping and holding on the bookmarks button.
Settings
Known Issue
Some icons are missing in Settings and only appear after the row is tapped.
Setup
Known Issue
Updating the iCloud settings screen may appear to hang during setup.
Workaround: Some accounts may have an extra long lag. Wait a couple of minutes and they should complete.
Siri
Known Issue
Calling contacts with Siri is supported only on devices with the latest developer seed build. Prior developer seed builds no longer support this feature.
Springboard
Fixed in beta 5
Some projects may launch in portrait when the destination device is in landscape.
Workaround: Rotate the device to portrait and back to landscape to continue in landscape.
Stores
Known Issue
Sometimes, loading certain pages or performing a search on the App Store or iTunes Store can be slow.
UIKit
Notes
UILabel has a default value of YES for clipsToBounds. This differs from the normal UIView default of NO.
leftLayoutGuide and rightLayoutGuide API have been removed. Please use the layoutMargins property instead.
Fixed in beta 5
When the width of a multiline label changes due to changes in the layoutMargins of some view, the intrinsic content size of the label is not invalidated when it should be. As a result the layout can unexpectedly truncate the label (or text view).
To use an action sheet-style UIAlertController on iPad, the sourceView of the alert controller's popoverPresentationController must be set.
Wi-Fi Calling (T-Mobile US only)
Note
The carrier name in the status bar will show “T-Mobile Wi-Fi” when the device is able to make and receive Wi-Fi Calls.
WebKit
Notes
Subpixel rendering is now on by default for all web content. Websites or in-app web views with extremely tight design constraints may render differently. Solutions for each issue will vary, but use Web Inspector to adjust position, border thickness, and width or height of elements.
In iOS 8.0 beta 2 and later, CSS object model getters (offset{Left|Top|Width|Height} and client{Left|Top|Width|Height}) return fractional double values based on subpixel metrics instead of rounded integral values.
The minimal-ui viewport property is no longer supported in iOS 8.
Known Issue
The window.outerWidth and window.outerHeight DOM properties always return 0. Other DOM properties will need to be used instead. This may affect websites that use leaf.js.
iOS 8 includes over 4,000 new APIs that let you add amazing new features and capabilities to your apps. Deeper integration with iOS means you can extend the reach of your app content and functionality. And with bold new technologies for game development, you can create even more incredible, responsive, and immersive gaming experiences.
iOS 8 lets you extend select areas of the system by supplying an app extension — code that enables custom functionality within the context of a user task. iOS supports app extensions for the following extension points.
By providing more sharing options, iOS 8 enables your app to share photos, videos, websites, and other content with social websites and other entities.
Photo Editing
Embed your filters and editing tools directly into the Photos app, so users can easily apply your effects to images and videos without having to import them into your app.
Custom Actions
Create your own custom action buttons in the Action sheet to let users watermark documents, add something to a wish list, translate text to a different language, and more.
Today
Your apps can now display widgets in the Today view of Notification Center, providing quick updates or enabling brief tasks — for example, posting updates on package deliveries, the latest surf reports, or breaking news stories.
Storage Provider
You can now provide a document storage location that can be accessed by other apps. Apps that use a document picker view controller can open files managed by the storage provider or move files into the storage provider.
Document Picker
The document picker view controller grants your users access to files outside your app’s sandbox. Documents are easily shared between apps, enabling users to edit a single document in multiple places.
Custom Keyboard
With iOS 8, you can provide custom keyboards with different input methods and layouts for users to install and use systemwide.
New Capabilities
iOS 8 introduces a huge set of APIs and services, so you can create new categories of apps and features. Here are some of the most exciting new capabilities we’re unlocking.
Touch ID
Your app can now use Touch ID to authenticate a user before accessing some or all content in your app. Fingerprint data is protected and never accessed by iOS or other apps.
PhotoKit provides new APIs for working with photo and video assets, including iCloud Photos assets, that are managed by the Photos app, so your app can edit photos directly in the Camera roll without having to import them first. Key features include a thread-safe architecture for fetching and caching thumbnails and full-sized assets, requesting changes to assets, observing changes made by other apps, and resumable editing of asset content.
The AVFoundation framework makes it easier than ever for users to take great photos. Your app can take direct control over the camera focus, white balance, and exposure settings. Your app can also use bracketed exposure captures to automatically capture images with different exposure settings.
HeathKit allows apps providing health and fitness services to access shared health-related information in one place. A user’s health information is stored in a centralized and secure location and the user decides which data should be shared with your app.
Your app can access any shared health-related information and can provide information about the user without you needing to implement support for specific fitness-tracking devices. Information can come from devices connected to an iOS device or manual entry by the user. Learn more
HomeKit
This is a new framework for communicating with and controlling connected devices in a user’s home. Your apps can enable users to discover devices in their home and configure them, or you can create actions to control those devices. Users can group actions together and trigger them using Siri. Learn more
CloudKit
Leverage the full power of iCloud and build apps with the new CloudKit framework. Now you can easily and securely store and efficiently retrieve your app data like structured data in a database or assets right from iCloud. CloudKit also enables your users to anonymously sign in to your apps with their iCloud Apple IDs without sharing their personal information.
With CloudKit, you can focus on your client-side app development and let iCloud eliminate the need to write server-side application logic. CloudKit provides authentication, private and public databases, and structured and asset storage services — all for free with very high limits. Learn more
Handoff
Using a simple API in Foundation, your app can participate in Handoff to let users start an activity on one device and seamlessly resume the activity on another device.
Technology improvements in iOS 8 make it easier than ever to implement your game’s graphics and audio features. Take advantage of high-level frameworks for ease-of-development, or use new low-level enhancements to harness the power of the GPU.
SceneKit
SceneKit is a high-level 3D graphics framework that helps you create 3D animated scenes and effects in your apps. It incorporates a physics engine, a particle generator, and easy ways to script the actions of 3D objects so you can describe your scene in terms of its content — geometry, materials, lights, and cameras — then animate it by describing changes to those objects. SceneKit’s 3D physics engine enlivens your app or game by simulating gravity, forces, rigid body collisions, and joints. It’s also completely integrated with SpriteKit, so you can include SpriteKit assets in 3D games.
The SpriteKit framework adds new features to make it easier to create high-performance, battery-efficient 2D games. With support for custom OpenGL ES shaders and lighting, integration with SceneKit, and advanced new physics effects and animations, you can add force fields, detect collisions, and generate new lighting effects in your games. Xcode 6 also incorporates new shader and scene editors that save you time as you create your game. Create a scene’s contents, specifying which nodes appear in the scene and characteristics of those nodes, including physics effects. The scene is then serialized to a file that your game can easily load.
With extremely low-overhead access to the A7 GPU, Metal enables incredibly high performance for sophisticated graphics rendering and computational tasks. Metal eliminates many performance bottlenecks that are found in traditional graphics APIs. It’s specifically designed to exploit modern architectural considerations, such as multiprocessing and shared memory, to make it easy to parallelize the creation of GPU commands. Metal offers a streamlined API, a unified graphics and compute shading language, and Xcode-based tools.
Swift is an innovative new programming language for Cocoa and Cocoa Touch with concise yet expressive syntax. Writing Swift code within an Xcode 6 playground shows instant results, while finished apps are compiled into high-performance native machine code. The Swift language is fast, modern, safe, and interactive. Learn more about Swift
iOS SDK 7.1 provides support for developing iOS apps, and it includes the complete set of Xcode tools, compilers, and frameworks for creating apps for iOS and OS X. These tools include the Xcode IDE and the Instruments analysis tool, among many others.
With this software you can develop apps for iPhone, iPad, or iPod touch running iOS 7. You can also test your apps using the included iOS Simulator, which supports iOS 7. iOS SDK 7.1 requires a Mac computer running OS X v10.8.4 (Mountain Lion) or later.
This version of iOS is intended for installation only on devices registered with the Apple Developer Program. Attempting to install this version of iOS in an unauthorized manner could put your device in an unusable state.
The following issues relate to using iOS SDK 7.1 beta 5 to develop code.
Bluetooth
Known Issue
32-bit apps running on a 64-bit device cannot attach to BTServer.
CFNetwork
Notes
A compatibility behavior has been added to address an issue where some web servers would send the wrong Content-Length value for “Content-Encoding: gzip” content. Previously,NSURLConnection and NSURLSession would send a “network connection was lost” / NSURLErrorNetworkConnectionLost (-1005) error in this situation.
The compatibility behavior applies only if the Content-Length value exactly matches the expanded gzip’d content. It won’t apply for “off by 1” or similar miscounting.
Safari
Notes
A property, minimal-ui, has been added for the viewport meta tag key that allows minimizing the top and bottom bars on the iPhone as the page loads. While on a page using minimal-ui, tapping the top bar brings the bars back. Tapping back in the content dismisses them again.
For example, use <meta name="viewport" content="width=1024, minimal-ui”>.
Siri
Notes
This seed adds new natural-sounding Siri voices for English (Australia), English (United Kingdom), Japanese, and Chinese (Mandarin - China).
The iOS device initially uses a compact voice for Siri. After you have configured a Wi-Fi network and have the device connected to a power source, iOS will automatically download and install a higher quality version.
Sync
Known Issue
In some situations, the “Connect to iTunes over USB to re-enable Wi-Fi Sync” prompt is not shown after an update as expected. Connecting to iTunes to re-enable Wi-Fi Sync is still required (and still functions as expected), it is just that the UI is not shown.
After upgrading to beta 5, iTunes Wi-Fi Sync users should connect their devices to their hosts to re-pair to enable wireless syncing.
If a UITextField or a UILabel that is baseline aligned with constraints has attributes that change after the constraints have been added, the layout may be incorrect. The exception to this is -setFont: on UILabel, which should work as expected.
Workaround: Avoid making changes in UITextField or UILabel after adding baseline-alignment constraints. If you must make changes, you should remove the constraints and then reapply them afterward. Note that this is a performance hit, so don’t do it unless it is necessary.
Reimagine your apps on iOS 7. Download the SDK today and take advantage of the new multitasking APIs, dynamic motion controls in UIKit, AirDrop, Sprite Kit, enhanced video APIs, new features in Game Center and Map Kit, and so much more.
Design and Develop for iOS 7
User Interface
Elevate the content of your apps and make your user interface come alive on iOS 7. Adopt the new design to simplify and revitalize your app with clarity, translucency, and depth. UIKit allows you to incorporate realistic motion and transitions with new APIs that enable your user interface to respond to every touch and swipe by following the behaviors and physical constraints you define. Take advantage of powerful new text layout tools and dynamic type that respect the design principals of iOS 7.
Share photos, documents, URLs and other types of data with multiple devices nearby by adding AirDrop support to your app. By simply adding the Activity sheet, all the details of sharing your content peer-to-peer is handled for you—no network or setup required. And with Wi-Fi peer-to-peer technology you can use the same underlying technology to directly connect with multiple devices nearby, and let your users easily share information with each other.
Keep the content of your app up-to-date by adopting the new multitasking APIs in iOS 7. The new services allow your app to update information and download content in the background without draining the battery unnecessarily. The updates can happen at opportunistic times and are intelligently scheduled according to usage, so your app can update content in the background just when your users need it.
Create new immersive experiences using the latest game technologies in iOS 7. Develop high-performance 2D games with the powerful new Sprite Kit framework, which combines everything you need to animate sprites, simulate physics and create beautiful particle systems all in one easy-to-use set of APIs. Hand the controls over to your users by adding support for upcoming MFi game controllers to your game. And the re-designed Game Center adds more modes for turn-based games and more leaderboards, as well as allowing you to authenticate players, and securely transmit game scores and achievements.
Let your users capture and compose photos and videos just the way they want. Capture video at 60fps, so you can replay dramatic scenes in slow motion. Get a closer look by directly controlling the zoom level of the camera. Create video effects and transitions by combining multiple video tracks using the custom video compositing APIs. Scan and recognize barcodes with the camera.
Enhance your apps with support for new types of accessories. Location beacons are a new class of low-powered, low-cost transmitters that can notify nearby iOS 7 devices of their presence. Location beacons will provide apps a whole new level of location awareness, such as trail markers in a park, exhibits in a museum or product displays in stores. Other new features include the ability to setup and configure Wi-Fi accessories, such as AirPlay speakers, directly from iOS. And iOS 7 works with more Bluetooth LE profiles, including time, notifications, keyboards, and stereo sound.
Now your apps can make beautiful music together. With Inter-App Audio, apps can register their audio streams to share with other apps. For example, a series of apps could publish audio streams of instrument tracks while another uses the combination of these streams to compose a song. Inter-App Audio also provides for MIDI control of audio rendering, remotely launching other registered Inter-App Audio apps and more.
Take your apps in new directions with the new features of Map Kit. iOS 7 introduces directions APIs, enabling you to guide users to their destinations from within your app. Allow your users to rotate and move around the map in 3D using updated views and controls. And you have even more control of overlays, making it possible to place them at different layers or replace portions of the map altogether.
iOS 7 beta supports iPhone 4, iPhone 4S, iPhone 5, and iPod touch (5th generation). Support for iPad 2, iPad with Retina display, and iPad mini is coming later this summer.
