iOS SDK Release Notes for iOS 8.0 Beta 3

Contents:

Introduction

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.

Bug Reporting

To report any bugs not mentioned in the Notes and Known Issues section, use the Bug Reporter app or Bug Reporter on the Apple Developer website (http://developer.apple.com/bugreporter/). You can quickly get to the Bug Reporter app from the Notifications Panel. Additionally, you may discuss these issues and iOS SDK 8.0 in the Apple Developer Forums: http://devforums.apple.com. To get more information about iCloud for Developers, go tohttp://developer.apple.com/icloud.

Notes and Known Issues

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

Authentication

Fixed in beta 3

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

AVCapture

Fixed in beta 3

The API returns incorrect values in some cases.

Known Issues

Backup

Fixed in beta 3

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

Fixed in beta 3

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

Workaround: Launch Notification Center, then reboot the device.

Bluetooth

Fixed in beta 3

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

Fixed in beta 3

  • 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.

CarPlay

Fixed in beta 3

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

Known Issues

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

CFPreferences

Fixed in beta 3

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

Workaround: Reboot the device.

CloudKit

Fixed in beta 3

Sometimes, very large syncs may fail.

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.

Contacts

Notes

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 iOS 8 beta 3, 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.

Fixed in beta 3

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 3

  • 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.

  • 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.

  • Own app’s container does not show up in document picker.

Known Issues

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

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

  • Document providers may hang when importing files.

  • 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 or reboot the device.

  • Selecting a file in a document picker twice in a row may cause the document picker to hang.

    Workaround: Force quit the app.

  • After rotating document picker to landscape the status bar is hidden.

  • Upon bringing up document picker in landscape, the containing view may be shifted beneath the navigation bar.

  • Auto layout does not provide direct support for the layoutMargins property of UIView currently.

Extensions

Fixed in beta 3

  • 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.

  • Sometimes your Sharing or Action extension can hang.

    Workaround: 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.

  • 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.

  • Extensions sometimes fail to launch when debugging from Xcode.

FaceTime

Known Issue

FaceTime does not work properly in landscape orientation.

Family Sharing

Fixed in beta 3

  • You can’t approve an “Ask to Buy” request from the requestor’s iOS device.

  • Push notifications are not received.

  • “Ask to Buy” request notifications do not appear, and requests are not actionable from devices running iOS 8 beta 2.

  • 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.

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 theURLForDirectory:inDomain:appropriateForURL:create:error: method of the NSFileManager class. 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.

Fonts

Known Issue

Some Hindi strings are incorrectly displayed, causing search and rendering issues.

Game Center

Fixed in beta 3

Invites to matchmaking may get stuck on Waiting.

Workaround: Use automatch.

Known issue

Swiping or tapping a Game Center friend request notification anywhere automatically accepts the friend request..

Handoff

Note

Handoff is incompatible between devices using this beta and the prior beta. You should test Handoff with the most recent beta software because it is not backward-compatible with previous betas.

Fixed in beta 3

  • 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.

  • Using the recovery option can leave you in a state where new items added to the keychain do not sync.

    Workaround: Use approval method with other devices unlocked.

Keyboards

Fixed in beta 3

  • In some cases, you may need to restart an app to get third-party keyboard input to register.

  • The requestSupplementaryLexiconWithCompletion: method does not return any lexicon entries.

  • On-screen keyboards do not correctly respond to some notifications (such as layout changes made in Settings).

    Workaround: Stop the running process and relaunch it or reboot the simulated device.

  • Keyboard keys are not being highlighted on some previous-generation devices.

  • When selecting a keyboard app in the Add New Keyboard menu, you may see an empty sheet. This happens when the containing app has a single keyboard target.

    Workaround: To add the keyboard, tap Done on the top-right of the sheet.

  • The Delete button may not show up when trying to remove an iPad keyboard.

  • Data Activation Strings “Location is required”, “Location Unavailable”, “Location Disabled”: not translated in all languages

  • Camera: most UI is not translated in all languages

Location Services

Fixed in beta 3

When Location Services is turned on, the device’s current location is used to suggest relevant apps on the lock screen. These suggested apps will remain on the lock screen even after leaving the relevant location.

Lock Screen

Fixed in beta 3

  • Sometimes devices may not wake when the home button is pushed.

    Workaround: Use the sleep/wake/power button.

  • Tapping Emergency on the lock screen does not do anything.

Known issue

Location-based recommended apps will not display on the lock screen.

Lost Mode

Fixed in beta 3

  • A device doesn’t display the Lost Mode message in the lock screen if the device was locked at the time it was put into Lost Mode.

    Workaround: Reboot the device.

  • After remote wiping a device and logging into the same (@icloud.com) iCloud account, the Lost Mode lock screen is displayed and the device cannot be unlocked.

Mail

Fixed in beta 3

Sometimes Mail crashes when replying to an email with an attachment.

MapKit

Fixed in beta 3

Taking multiple snapshots using MKMapSnapshotter can sometimes produce a distorted map snapshot.

Metal and OpenGL

Known issue

Shadow samplers are broken when using linear filtering.

Workaround: For OpenGL, set GL_TEXTURE_MIN_FILTER and GL_TEXTURE_MAG_FILTER to GL_NEAREST. For Metal, set the mag_filter and min_filter sampler properties to nearest in the shader source.

Messages

Fixed in beta 3

  • SMS relay may not work until an iMessage is sent from the device.

  • The keyboard may cover the predictive text bar if you launch Messages from the App Switcher.

Known issue

If you have Send As SMS enabled in Messages Settings, the Messages app may periodically become unresponsive.

Workaround: Reboot your device.

Newsstand

Known Issue

Content downloaded via NKAssetDownload doesn’t get returned to the app.

Notification Center

Note

The schedule and intended use of widgetPerformUpdateWithCompletionHandler: has changed from previous betas. It is now 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 the 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.

Notifications

Fixed in beta 3

User notification custom action buttons don’t show when context is only set to UIUserNotificationActionContextDefault.

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: NSURLSessionTaskPriorityDefaultNSURLSessionTaskPriorityLow, andNSURLSessionTaskPriorityHighNSURLSessionTask 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 ofNSURLSessionTask performance.

For complete usage details of NSURLSessionTask priorities, refer to the NSURLSession.h header file, which is provided by the Foundation framework.

Passbook

Fixed in beta 3

Passes added on iOS 7 devices won’t appear in iOS 8 devices, and vice versa.

Phone

Notes

To activate Wi-Fi Calling functionality for T-Mobile (US only), please follow these steps:

  • Go to Settings -> Phone -> Wi-Fi Calling

  • Toggle the ‘Wi-Fi Calling’ switch to ON

  • If the carrier does not have user’s registered emergency address, you will be asked to add it before the feature is activated

Fixed in beta 3

  • Bringing up a contact card in Mail during a call causes a hang.

  • Phone call relay uses Bluetooth when it should be using Wi-Fi. Since not all devices have the necessary Bluetooth support, this may fail on some hardware.

Known issue

Call UI may appear on top of the home screen when it is originated from the app switcher.

Photos

Notes

  • You need to upgrade to beta 3 to use iCloud Photo Library. Beta 1 and 2 will no longer supports this feature.

  • Back up your photo libraries before enabling iCloud Photo Library by:

    • Importing to your Mac using iPhoto

    • Importing to your Mac using Image Capture

  • Enabling iCloud Photo Library will not add photos/videos that have been synced with iTunes to the cloud.

  • 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.

Fixed in beta 3

  • Slow motion clips that have been trimmed sync to other devices as a gray thumbnail.

  • iCloud Photo downloads stall when a device is idle for a long period of time.

    Workaround: Sync resumes when the device wakes up.

  • iCloud Photo Library does not upload Photos synced from iTunes.

Known Issues

  • The ability to automatically optimize device space is not enabled in this beta.

  • When using iCloud Family, both iCloud Photos and My Photostream are enabled.

  • After restore from iCloud backup, modified photos may show unmodified thumbnails.

  • If you reach your iCloud quota, there is no way to add or delete data within the Photos app.

  • If both iCloud Photos and Photostream are enabled, duplicate photos are displayed.

  • After upgrading to beta 3, your device may get stuck while uploading photos to iCloud.

    Workaround: Reboot the device.

PhotosUI

Fixed in beta 3

PHContentEditingController protocol methods may be called on background threads.

Reminders

Fixed in beta 3

When you select Edit in a list of reminders and then scroll, reminders in the list are no longer editable.

Safari

Note

  • Safari now blocks ads from automatically redirecting to the App Store without user interaction. If you still see the previous behavior, or find legitimate redirection to the App Store to be broken in some way, please file a bug.

  • You can now quickly add a site to Shared Links or save a bookmark by tapping and holding on the bookmarks button.

Settings

Fixed in beta 3

  • You are unable to use the “Forgot Apple ID or Password” dialog on your device.

    Workaround: Reset passwords from appleid.apple.com.

  • The username and password fields in iCloud Settings do not display properly.

Setup

Known Issues

  • Updating the iCloud settings screen may appear to hang during setup.

Known Issues

  • Apps deployed to CarPlay do not launch or display controls.

  • If you rename Xcode.app after having previously run it, Simulator stops working.

    Workaround: Reboot or revert the name change.

  • The software keyboard in the resizable iPhone sim does not appear.

    Workaround: The hardware keyboard can still be used for text input.

  • The resizable sim will not resize while social, photo sharing, or action extension items are displayed.

    Workaround: Dismiss the view, app switch to another app and back.

Siri

Fixed in beta 3

  • Localized strings for Voice Activation phrases don’t appear in Settings > General > Siri.

    Voice Activation phrase for each Siri Language:

    • English (US, UK, AU, CA): Hey Siri

    • French (FR, CA, CH): Dis Siri

    Workaround: Reboot the device to have Siri activate as expected.

Known issues

  • Speaking “Hey, Siri” may fail to launch Siri for subsuquent requests if you leave the UI by tapping the home button while Siri is still speaking.

    Workaround: Re-launch Siri with the home button, speak your request, and do not exit the UI until Siri finishes speaking.

  • The ‘Hey, Siri’ feature is not available when Japanese is selected in Settings -> General -> Siri -> Language.

Springboard

Known Issues

  • Some projects may launch in portrait when the destination device is in landscape.

    Workaround: Rotate the device to portrait and back to landscape to continue in landscape.

  • SpringBoard will crash when a device is locked while viewing a folder.

    Workaround: Exit folder before locking device.

Stores

Known issue

Sometimes, loading certain pages or performing a search on the App Store or iTunes Store can be slow.

UIKit

Note

UILabel has a default value of YES for clipsToBounds. This differs from the normal UIView default of NOfalse.

Fixed in beta 3

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

Known Issue

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.

Weather

Known issue

On iPhone 4S, Weather is missing it’s background color, letting the wallpaper see through behing the condition animations.

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.

  • When passing information from a UIWebView back to a native app using a custom URL scheme, the URL must be well-formed or WebKit will not issue a load request, and thus the -webView:shouldStartLoadWithRequest:navigationType: UIWebViewDelegate method will not be called.

    Workaround: Typically this means properly encoding each part of the URL, such as placing a query string after a ‘?’ character.

Fixed in beta 3

  • 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.

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

Known issue

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

You can leave a response, or trackback from your own site.
