iOS 5 GM - Changelog

    iOS 5 GM - ChangelogFew minutes ago we broke the news when Apple released iOS 5 GM (Gold Master) which is the pre-final version of iOS 5. Final version of iOS 5 scheduled to release for public by October 12 as Apple confirmed in it's event today in Cupertino. Now let's check out iOS 5 Full Changelog after the jump.


    When creating an iCloud account, you can use any Apple ID as long as it is a full email address and not a MobileMe account. If you have a MobileMe account, you can move that account to iCloud. You can find more information at:

    Starting in iOS 5, AirPlay is enabled by default for video content in applications and websites.
    In iOS 5, AV Foundation adds support for video playback via AirPlay.

    The NSNetService class and CFNetService APIs do no include P2P interfaces by default. To browse, register, or resolve services over P2P interfaces, an application needs to use the Bonjour DNSService*() APIs noted below.
    Setting the interfaceIndex parameter to kDNSServiceInterfaceIndexAny in the following API’s will not include P2P interfaces by default. To include P2P interfaces, you must now set thekDNSServiceFlagsIncludeP2P flag when using kDNSServiceInterfaceIndexAny or set the interfaceIndex to kDNSServiceInterfaceIndexP2P. The affected APIs are:
    API Validation

    In the iOS 5 development tools, it is possible to extract APIs used by an application and have them checked for use of private APIs. This option is offered when you validate your application for app submission.
    Apple TV

    The Apple TV Software enables users to mirror the contents of an iPad 2 to an Apple TV (2nd generation) using AirPlay. This software also enables Photo Stream on Apple TV so users can access photos stored in iCloud. Apple TV Software beta is being provided to test the latest AirPlay functionality with your iOS 5 apps and web sites. If you wish to install Apple TV Software beta on your device, you must first register your device UDID in the iOS Developer Program Portal.
    Automatic Reference Counting

    In Xcode, if the configuration is set to Device and there is a space in the path of one of the source files (more commonly, the project is inside a directory with spaces), the “Convert to Automatic Reference Counting” step (after Precheck) will fail with error: Error in format of file: .If encountered, the user should switch to Simulator and retry the migration.
    Binary Compatibility

    On applications linked against the iOS 5 SDK, scroll view content offsets will no longer be rounded to integral pixels during a pinch gesture.

    Match data for turn-based matches is limited to 4 KB.
    FIXED: Auto-matching with the turn-based view controller does not work. Invites or the direct auto-match API can be used as a workaround.
    iCloud Backup

    Backups made prior to September 22nd are no longer available. It is strongly advised to upgrade to this version of iOS 5 in order to continue backing up your devices
    iCloud Storage

    In the iCloud key-value store, the maximum number of keys has been raised to 256.
    All newly generated provisioning profiles are now automatically enabled for iCloud. If you are using an Xcode managed Team Provisioning Profile, click refresh in the Xcode Organizer to obtain a new iCloud-enabled profile. To enable all other provisioning profiles for iCloud, simply regenerate your profiles in the iOS Provisioning Portal.
    If your application is using the NSMetadataQuery class, you must set a predicate and the predicate is now honored. But the predicate is an NSPredicate-style predicate, not a Spotlight-style predicate. An example of the difference is that you must use LIKE instead of = for wildcard matching. The differences are defined in more detail at:
    The setSortDescriptors: method of NSMetadataQuery is not supported.
    To enable iCloud storage within your apps in iOS 5, click the Enable Entitlements checkbox in the Summary pane of your project. Xcode creates a custom entitlements file for your project that automatically includes your Team ID. You can add additional iCloud Container values as required by your application. (Note that you must regenerate your existing provisioning profiles, either with Xcode or in the iOS Provisioning Portal, to use iCloud storage.)
    The container identifier string you pass to the URLForUbiquityContainerIdentifier: method of NSFileManager must include the team ID at the beginning of the string. As a convenience, you can pass nil to retrieve the first document container ID specified in your app’s entitlements.
    In iOS 5, files that are protected via Data Protection cannot be used with iCloud Storage APIs.
    File presenters—objects that adopt the NSFilePresenter protocol—do not receive some of the messages that they are supposed to receive, including:
    As a work around, implement the relinquishPresentedItemToWriter: method and check to see if the writer actually wrote when your file presenter reacquires the file.
    If you report a bug related to the iCloud storage interfaces, please include the logs collected during your debugging session. To generate these logs, you must install a special debug profile on your device.The debug profile can be obtained from This profile enables the generation of debug logs that are needed to diagnose any problems using iCloud storage. The instructions to collect the logs are:
    Install the profile. (The easiest way to do this is to mail it to yourself and open the attachment on your device.)
    Reproduce the bug.

    Sync with iTunes to pull the logs off your device.
    Attach the logs to your bug report. You can find the logs in ~/Library/Logs/CrashReporter/MobileDevice/DeviceName/DiagnosticLogs.
    These logs can grow large very quickly, so you should remove the profile after you have reproduced the problem and pulled the logs of your device.
    File names are case-insensitive in Mac OS X but case-sensitive in iOS. This can lead to problems when sharing files between the two using iCloud. You should take steps on iOS to avoid creating files whose names differ only by case.

    The version of iTunes that comes with the GM release cannot sync devices that have the beta 7 software installed. To avoid this problem, do the following:
    Sync any devices that have beta 7 installed to the version of iTunes that came with beta 7.
    Upgrade iTunes to the version that comes with the GM release.
    Connect the device and install the GM software. (Understand that you might see a failure to sync error when you first connect the device.)
    After installing the GM software, restore from your backup you made in step 1.
    Music Player

    FIXED: When deleting a song or video from Music/Videos on the device, the Music Player app crashes.

    In iOS 5, the signing of certificates with MD5 signatures is not supported. Please ensure that certificates use signature algorithms based on SHA1 or SHA2.

    Push and local notifications for apps appear in the new Notification Center in iOS 5. Notification Center displays notifications that are considered “unread.” To accommodate push and local notifications that have no unread status, set your application’s badge count to 0 to clear that app’s notifications from Notification Center.
    UI Automation

    When using the performTaskWithPathArgumentsTimeout method of UIAHost in a UI Automation script where the API outputs excessively (say, thousands of lines of text) to standard out or standard error, the task may deadlock until the timeout is reached, at which point it will throw a JavaScript exception.
    The lock() and unlock() functions of UIATarget have been replaced with the lockForDuration() function.
    In iOS 5, you can now trigger the execution of a UI Automation script on an iOS device from the host terminal by using the instruments tool. The command is:
    instruments -w -t
    When using the cli instruments for UI Automation you can now target the default Automation Template and pass the script and results path into the tool as environment variable options. For example:
    instruments -w -t /Developer/Platforms/iPhoneOS.platform/Developer/Library/Instruments/PlugIns/AutomationInstrument.bundle/Contents/Resources/Automation.tracetemplate -e UIASCRIPT
