iOS SDK Release Notes for iOS 8.0 Beta



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.

Notes and Known Issues

The following issues relate to using iOS SDK 8.0 to develop code.

App Store

Known Issue

Links to Developer websites from an apps developer page are broken.


Known Issues


Known Issue

Certain apps may crash on launch consistently if they came over from a Restore from Backup.

Workaround: Delete and re-download the app.

Bug Reporter

Known Issues

  • The switch in Developer Settings to hide Bug Reporter is not working.

    Workaround: Remove it from the Notification tab in Notification Center settings.

  • The Bug Reporter icon does not appear on the Home Screen on iPad.

    Workaround: Open the app from the Notification tab in Notification Center settings.

Camera connector

Known Issue

When attached, the camera connector is not offered as an import option.


Known Issues

  • After using Siri, audio quality goes to 24KHz regardless of where it was originally set.

  • CarPlay may crash when pressing the Back button when in Now Playing.

  • When using the knob only, the highlight can move off screen but the scroll position of view doesn't follow.

  • The Now Playing screen is missing the Back button in the top-left corner.


Known Issue

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 back off.



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.

In this beta, you have the choice of using either the new mode or the old mode. The old mode will be deprecated in a future iOS 8 Beta, so you should migrate to the new mode as soon as possible.

See the new PeoplePicker: Picking a Person or Property sample project demonstrating usage of the new mode.


Known Issues

  • openURL does not work from an extension.

  • When Extension with UI is killed, it relaunches and is not dismissed.

  • Certain types of media, such as those synced from iTunes, are not editable in the Photos app.

  • Sharing extensions are enabled by default.

  • Sharing extensions display the name of the project instead of the name of the target.

  • If a Sharing extension or an Action extension hangs, it may be necessary to kill the hosting application.

  • Using xpc_service_set_attach_handler to profile app extensions for keyboard does not work.

    Workaround: Run your app extension in Simulator, then trigger the Keyboard extension to load and attach to the running instance (for example, (123)) from Instruments’ target chooser.

  • Sometimes Sharing or Action extensions are not updated properly after enabling or disabling.

    Workaround: Dismiss the Share sheet and relaunch it.

  • During a debug session, extensions may time out before loading.

  • Action extension view controllers do not support full-screen presentation.

  • Passing NSExtensionItem or NSItemProvider instances to UIActivityViewController does not work.

    Workaround: Log out and back in to iTunes to correct the issue.

  • File Provider extension will not load if changes are made to an existing file provider on device.

    Workaround: You need to either reboot the device or delete the app and reinstall it.

File System


The file system layout of app containers has changed on disk. Rather than relying on hard-coded directory structure, use the NSSearchPathForDirectoriesInDomains function or the URLForDirectory:inDomain:appropriateForURL:create:error: method of the NSFileManager class. See Accessing Files and Directories.
