Apple releases iOS 8.2 beta 2 for developers

Apple has just released the second beta of iOS 8.2 to developers, for testing, as an over-the-air update.  The beta can also be downloaded from Apple’s developer site. iOS 8.2 includes WatchKit, so developers can create apps and Glances for Apple Watch. You can read about how such apps work with our previous coverage of the WatchKit APIs. Apple released the first beta of iOS 8.2 a few weeks ago.

The latest update, which brings the build number from 12D436 to 12D445d, follows yesterday’s public release of iOS 8.1.2 which included bug fixes for non-developers. Apple also released Xcode 6.2 beta 2 alongside the new iOS 8.2 beta today.

As 8.2 revolves around developer toolkit support for Apple Watch, there is unlikely to be any significant user-facing changes to iOS itself, aside from the obligatory roll out of bug fixes and performance improvements. We’ll update if we notice anything however …

        Notes and Known Issues
        Introduction
        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.

        For more information and additional support resources, visit http://developer.apple.com/programs/ios/.

        Bug Reporting
        For issues not mentioned in the Notes and Known Issues section, please file bugs through the Apple Developer website (https://developer.apple.com/bug-reporting/ios/). Additionally, you may discuss these issues and iOS SDK 8.2 in the Apple Developer Forums: http://devforums.apple.com. To get more information about iCloud for Developers, go to http://developer.apple.com/icloud.

        Notes and Known Issues
        The following issues relate to using iOS SDK 8.2 to develop code.

        CloudKit
        Note
        A single CKAsset instance can no longer be set as a value on multiple CKRecords.

        Document Providers
        Notes
        Your app needs the iCloud entitlement to be able to be used as a document provider.
        The com.apple.developer.icloud-container-identifiers entitlement is required.
        Known Issues
        After rotating the document picker to landscape, the status bar is hidden.
        Upon bringing up the document picker in landscape, the containing view may be shifted beneath the navigation bar.
        App extensions
        Notes
        App extensions need an arm64 slice to run on 64-bit devices. If you try to run the armv7 slice on a 64-bit device it won’t work.
        Apps need to have an arm64 slice if the bundle contains a framework that both the app and the app extension link against.
        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 NSFileManager class. See Accessing Files and Directories in File System Programming Guide.

        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:

        CTLineGetBoundsWithOptions(lineRef, kCTLineBoundsIncludeLanguageExtents);
        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.

        Keyboards
        Fixed in beta 2
        Additional keyboards, including 3rd party keyboards, may not appear in Safari, Maps, or 3rd party apps in iOS Simulator.

        Messages
        Known Issue
        Your device may get into a state where tapping into Messages conversations can take a long time.

        Workaround: Reboot the device.

        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, 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
        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.
        Provisioning Profiles
        Known Issue
        If you have upgraded to the 8.2 beta from previous iOS 8 betas you may see your apps crashing due to provisioning profile issues.

        Workaround:

        Connect the device via USB to your Mac.
        Launch Xcode.
        Choose Window > Devices.
        Right click on the device in left column, choose “Show Provisioning Profiles”.
        Click on the provisioning profile in question.
        Press the “-” button.
        Continue to removing all affected profiles.
        Re-install the app.
        Siri
        Fixed in beta 2
        Siri support for Singapore English was disabled in the previous beta.

        UIKit
        Notes
        UILabel has a default value of YES for clipsToBounds. This differs from the normal UIView default of NO.
        The leftLayoutGuide and rightLayoutGuide APIs have been removed. Please use the layoutMargins property instead.
        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.
        A WatchKit app can ask its containing iOS app to perform functionality using the WKInterfaceController API openParentApplication:reply:. The app delegate of the containing app must implement application:handleWatchKitExtensionRequest:reply:.
        A page-based WatchKit app can dynamically resequence the pages at the root level using reloadRootControllersWithNames:contexts:.
        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 2
        Clicking on a notification’s icon/body in the watch window does not launch the main app in iOS Simulator.
        When you click Build and Run it doesn’t launch the watch window.
        The custom sash color for notification controllers does not currently appear in Interface Builder but does in iOS Simulator.
        Installing WatchKit apps may stop working in iOS Simulator.
        The WKInterfaceController method addMenuItemWithImage:title:action: does not work in iOS Simulator.
        Known Issues
        In iOS Simulator, the Emoji button is always visible, regardless of the selected input mode.
        The WKInterfaceController method presentTextInputControllerWithSuggestions:completion: is not fully supported in iOS Simulator. Text suggestions work, but Dictation and Emoji do not.
        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.

      • Thanks! Didn’t see them posted at the time I posted my comment. I will go read them now.
