Changelog:
Notes and Known Issues Apple ID Known Issue If you sign in with different Apple IDs for iCloud and iTunes during Setup Assistant, it may hang.
Workaround: Do not use different Apple IDs for iCloud and iTunes during Setup Assistant. After setup, sign in by going to Settings > App and iTunes Stores.
iCloud Keychain Note During the iOS 9.1 beta, iCloud Keychain accounts with two-factor authentication enabled will use beta servers. If you do not want your iCloud Keychain data stored on beta servers, do not use the beta software.
Fixed in Beta 3 If you disable two-factor authentication on your iCloud account, your iCloud Keychain may also get turned off. Workaround: Confirm that iCloud Keychain is still on in Settings after disabling two-factor authentication.
When activating iCloud Keychain in Settings on iPad, you may be unable to complete the activation. Known Issue Sometimes while setting up iCloud Keychain, you receive a "Could Not Set Up iCloud Keychain" error.
Workaround: Reboot the device.
Metal Note For tvOS Metal development, it is required that you use the tvOS-specific feature set enum MTLFeatureSet_TVOS_GPUFamily1_v1.
PhotoKit Known Issue If your app gets the gesture recognizer from the PHLivePhotoView object (via playbackGestureRecognizer) to install it on a different view, subsequently setting a new value for livePhoto on the PHLivePhotoView object causes it to reinstall the gesture recognizer on itself.
Workaround: Your app can get the gesture recognizer and reinstall it on the appropriate view every time after setting a value for livePhoto.
Podcasts Fixed in Beta 3 The sleep timer does not work in this beta.
Restore Fixed in Beta 3 If you’ve set a region that doesn’t match your language, restores from iCloud Backup might not progress.
Workaround: During restore, change your region to match your language. You can change it back after the restore is over.
Known Issue Sometimes while restoring from iCloud backup, you will not see your list of backups, if you have two-factor authentication enabled on your iCloud account.
Settings Known Issue Settings may become unresponsive after signing into an iMessage or FaceTime account.
Workaround: Quit Settings from the App Switcher.
Siri Known Issue When asking Siri to play music, Siri will return an error but will still play back the music requested.
UIKit Note On 3D Touch capable devices, touch pressure changes cause touchesMoved:withEvent: to be called for all apps running on iOS 9.0. When running iOS 9.1, the method is called only for apps linked with the iOS 9.0 (or later) SDK.
Apps should be prepared to receive touch move events with no change in the x/y coordinates.
