Notes and Known Issues

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

App Store

Fixed in beta 2

Links to Developer websites from an app’s developer page are broken.

Authentication

Known Issue

Projects using LocalAuthentication won’t build if the Destination is set to iOS Simulator.

AVCapture

Known Issues

• The API returns incorrect values in some cases.

• Use of the AVCaptureDevice method rampToVideoZoomFactor:withRate: will fail.

• Use of the new constant, AVCaptureISOCurrent, will result in inconsistent ISO values (as observed on the ISO property) if setExposureModeCustomWithDuration:ISO:completionHandler: is called repeatedly.

• In some configurations, the maxBracketedCaptureStillImageCount property on AVCaptureStillImageOutput will yield incorrect results.

Backup

Fixed in beta 2

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

Known Issue

If you do a clean installation, iCloud Backups may not be completely restored to your device.

Workaround: Use iTunes to back up and restore your iOS 8 beta devices.

Battery Life

Known Issue

Extensive console logging of NCLaunchstats may be a cause of reduced battery life.

Workaround: Launch Notification Center, then reboot the device.

Bluetooth

Known Issue

The CoreBluetooth State Preservation & Restoration feature does not work. If your application is jetsammed while in the background performing long-term action(s) with CoreBluetooth, those applications will cease and the application will not be restored.

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.

• The cursor may not get placed in the appropriate text field.

Camera Connector

Fixed in beta 2

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

CarPlay

Fixed in beta 2

• 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.

Known Issues

• 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.

CFPreferences

Known Issue

After memory pressure events, apps and system services may lose their preferences.

Workaround: Reboot the device.

CloudKit

Known Issues

• 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.

• Sometimes, very large syncs may fail.

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. SeeABPeoplePickerNavigationController.h for more details.

In iOS 8 beta 2, you must use the new mode. The old mode has been deprecated with this beta.

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

Known Issue

If the user selects a property from a unified contact, an incorrect person for that property may be returned by the people picker.

Document Providers

Note

Your app needs the iCloud entitlement to be able to be used as a document provider.

Fixed in beta 2

• After installing or modifying an existing document provider, you may need to restart the device for it to show in the available document providers.

• Import/open causes sandbox denial on first try.

Known Issues

• Document provider extensions sometimes crash when trying to import a document from a document provider view controller.

• Document providers may hang when importing files.

• Document provider extension will not load if changes are made to an existing document provider on device.

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

• App icons in the document picker do not show up on iPhones and iPads.

• After deploying a FileProvider via Xcode, your documentStorageURL may be nil and cause your extension to crash.

  Workaround: Force quit the app and re-use the extension.

• Moving some files via UIDocumentPickerViewController may cause a crash if the file was not created locally.

  Workaround: Create a local file in the iCloud container and use this URL to move files.

• Sometimes, bringing up a Document Provider UI Extension will not show up after redeploying the app via Xcode.

  Workaround: Force-quit the app, and then it should appear properly.

• FileProvider extensions do not see the host app’s file removed when copying the file to a shared group container.

Extensions

Fixed in beta 2

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

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

• Action extensions do not animate smoothly when dismissed.

• openURL does not work from an extension.

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

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

Known Issues

• 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, com.thirdparty.foo.keyboard (123)) from Instruments’ target chooser.

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

• Application extensions may behave unpredictably with respect to location access.

• Redeploying an extension may disable it in Notification Center.

  Workaround: To debug the Today view extension. use “Attach to process.”

• After redeploying an app, the Today view extension may not be launched, and sometimes its bundle display name becomes the name of the app.

  Workaround: Reboot the device.

FaceTime

Known Issue

FaceTime does not work properly in landscape orientation.

Family Sharing

Fixed in beta 2

• While using the iTunes Store you may experience a spinner that never completes.

• Login to iCloud may be slow on iOS.

• Shared purchase history page on Mac App Store and iOS App Store are disabled.

• Email invitations are not enabled; members can join using push notifications or via inline password entry flow.

• A blank screen may be seen after creating a family on iPad.

  Workaround: Tap on other settings and then back to iCloud settings.

• “Ask to Buy” and Family Notifications may not appear due to SpringBoard crashing.

  Workaround: Reboot.

File System

Note

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 NSFileManagerclass. See Accessing Files and Directories in File System Programming Guide.

Find My Friends

Note

Now that the Share My Location feature is integrated into Messages, Find My Friends only supports the Apple ID configured in Settings > iCloud.

Find My iPhone

Fixed in beta 2

• Directions and Navigation in Maps do not work with Handoff in this beta.

• In some cases, using Handoff with Safari will result in an old URL being resumed instead of the current URL.

Known Issues

• When using a Mac, Handoff may sometimes stop showing icons on other iOS and OS X devices. Powering the Mac off and then back on can sometimes work around this issue.

• Phone Calls to and from the Mac may sometimes not complete or send and receive audio.

HealthKit

Fixed in beta 2

• HKCorrelationQuery only returns objects that were saved with correlations. It should return all data entries matching the predicate.

• Blood pressure readings saved from Health will not have a correlation stored between the systolic and diastolic readings.

Known Issues

• HomeKit Bluetooth LE support is not enabled.

• When upgrading from an earlier beta, you may need to remove accessories from Home Kit Accessory Simulator and then re-add them.

iCloud Drive

Notes

• Upon upgrading to iOS 8 Beta, existing iCloud Documents & Data present (not evicted) on your device are copied into special server-side containers for use during the beta period.

• iCloud Documents & Data created with iOS 8 Beta will not sync with with Documents and Data managed with iOS 7, OS X Mavericks, or earlier operating systems.

• iCloud Documents & Data in iOS 8 Beta will only sync with devices running iOS 8 and OS X Yosemite Developer Preview.

• iCloud Documents & Data managed with iOS 7 or OS X Mavericks will remain unaffected.

• iCloud Documents & Data created with iOS 8 Beta will be deleted from the servers at some point during the beta period. Information downloaded and not evicted from the device will remain on device and will re-sync after the data wipe occurs.

Workaround: Set the context to both Default and Minimal.

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.

Known Issues

• Share sheets sometimes include the “Send to Shared Photostream” item when they should not.

• If an app is using a xib as its main window and is launched in landscape iPad, the main window will have the incorrect dimensions, causing significant distortion and difficulty using presented view controllers. An app may have to be force-quit after presenting a system view controller to function again.

  Workaround: Launch all apps in portrait before rotating to landscape.

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.

Fixed in beta 2

SecRequestSharedWebCredential and SecAddSharedWebCredential currently only work on device, not in Simulator.

Known Issues

• Applications that use Apache Cordova/PhoneGap are broken due to a bug that causes the window.navigator.userAgent object to become undefined when window.navigator is replaced by a pure JavaScript wrapper object.

• If you pass NULL for the fqdn parameter of SecRequestSharedWebCredential as recommended, only the first domain in the entitlement is used.

• Apps that play video in a UIWebView may fail playback.
