Fixed in beta 5

• Use of the MARKDOWN_HASHdae79d33ca99c414381c5251f4cd5e4bMARKDOWN_HASH method MARKDOWN_HASH0e99deb3290dc5d3347d121115affd12MARKDOWN_HASH will fail.

• In some configurations, the MARKDOWN_HASHdc6d8961b37480b4a541e40473facfe9MARKDOWN_HASH property on MARKDOWN_HASHc2b5861e8645dcd9690b0ee7f1b7704fMARKDOWN_HASH will yield incorrect results.

Known Issue

Use of the new constant, MARKDOWN_HASH8344932bbad9ac11a86b6aa1da25a1a1MARKDOWN_HASH, will result in inconsistent ISO values (as observed on the ISO property) if MARKDOWN_HASH9d8865950b7b5d1bd517c844c5620485MARKDOWN_HASHis called repeatedly.

Fixed in beta 5

A restoration of an iCloud backup onto the same device the backup was taken from may not work properly. As a result, some apps may crash.

Known Issues

• Encrypted backups to iTunes fail.

• iOS 7 iCloud backups restored to an iOS 8 beta device may not properly restore photos.

Fixed in beta 5

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

Fixed in beta 5

Clients sending multiple simultaneous record update requests to the same zone in the private database may encounter MARKDOWN_HASH653e312681ec7072609911ed276a931dMARKDOWN_HASH errors.

Workaround: Clients should send update requests for a given zone one at a time. In addition, they should handle MARKDOWN_HASH653e312681ec7072609911ed276a931dMARKDOWN_HASH errors by retrying with an exponential backoff.

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. See MARKDOWN_HASHdcfc7140cabc1d1217fd151d789396deMARKDOWN_HASH for more details.

As of iOS 8 beta 2, you must use the new mode. The old mode has been deprecated.

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

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 will be required when iOS 8 is released.

Fixed in beta 5

• App icons in the document picker do not show up on iPhone and iPad.

• Document providers may hang when importing files.

Known Issues

• 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.

• On iPhone, bringing up DocMenu from Locations in DocPicker, overlaps with status bar.

Known Issues

• 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.

Fixed in beta 5

• Keyboard extensions can now be profiled with Instruments.

• Extensions now more reliably support control of location access.

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

Fixed in beta 5

FaceTime does not work properly in landscape orientation.

Known Issues

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

• Items already owned by family members must be re-downloaded from the Purchased page (not Store pages) to get them free of additional charge.

Note

The file system layout of app containers has changed on disk. Rather than relying on hard-coded directory structure, use the MARKDOWN_HASH9648f252eff7e19e34857f2db8115ad0MARKDOWN_HASH function or theMARKDOWN_HASH60a798e1e81947ae7cd10138f6a4c016MARKDOWN_HASH method of the MARKDOWN_HASHbe13a29b4bdf6a9919fed9e67817e14fMARKDOWN_HASH class. See Accessing Files and Directories in File System Programming Guide.

Note

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

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:

1. Use MARKDOWN_HASHa4afb21925d0fac81e0197a0f9723d8dMARKDOWN_HASH 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.

2. 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:

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.

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.

Notes

• Spirometry data types are now available in HealthKit.

• Any blood type that was set in Medical ID prior to beta 3 will be cleared.

• The pairing UI for BTLE health devices has been removed from HealthKit and is now available in Settings > Bluetooth.

• The MARKDOWN_HASH2ff657bb95fe58a794fb9d34d14c92a8MARKDOWN_HASH API is now available to store workouts.

• MARKDOWN_HASHda85fe87313016879d79c98dd5a0f40cMARKDOWN_HASH has been renamed MARKDOWN_HASH5ea0ff104a26e01263855a409a2d4cd7MARKDOWN_HASH.

• The following MARKDOWN_HASH2adb14e9805fff47f69180ae97f9f3c0MARKDOWN_HASH identifiers have been removed:

  • MARKDOWN_HASH0e678b7d4c59dfbc6e1db10e48314e8aMARKDOWN_HASH

  • MARKDOWN_HASHd142fab3adc9e101c627f1f9ab99c08dMARKDOWN_HASH

  • MARKDOWN_HASH0edcdbd5b4fb8f1dc1a00ab6ea47aecbMARKDOWN_HASH

Note

• After upgrading to beta 5, you need to reset your home configuration in Settings > Privacy > HomeKit > Reset Home Configuration.

• You must sign into iCloud and enable Keychain sync to use HomeKit with this seed.

Known Issue

Siri may not immediately recognize HomeKit data changes.

Workaround: To trigger an update to Siri, edit other data used by Siri such as a contact or the name of a Reminders list.

Fixed in beta 5

iAd videos may not play in NPR HLS station.

Notes

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

• Document storage containers created using the MARKDOWN_HASH8c81d420dbd5a92621d1f4fc6f82519aMARKDOWN_HASH class in iOS 7 are not yet available for use with iCloud Documents through Xcode 6 beta or in the Certificates, Identifiers & Profiles section of Member Center. These containers will be migrated later and associated with your existing App IDs.

• MARKDOWN_HASH66a5628ec85f8a83a31e79c277c669e0MARKDOWN_HASH might return nil when running your application in Xcode. If so, open System Preferences, navigate to iCloud > iCloud Drive, and enable Xcode.

• Migrating to iCloud Drive will disable Documents & Data syncing for your iCloud account on iOS 7 and earlier devices, as well as OS X Mavericks and earlier Macs.

Fixed in beta 5

• Initial sync does not work if the approving device is locked when the approval occurs.

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

Known Issue

Upon logging into a device with the iCloud 8 beta, other devices in your keychain circle may have their access to the circle revoked.

Workaround: Enable iCloud Keychain Sync on your other devices again.

Known Issue

Apps do not sync from a device to iTunes.

Fixed in beta 5

• If you turn off predictive text in one app and then turn it back on in another, it may not actually be reactivated.

• Caps Lock may be unexpectedly enabled in text input fields.

Fixed in beta 5

The following have English strings that are now properly localized in other languages:

• VoiceOverTouch

• Sharing

• ManagedConfiguration

• AirPortAssistant

• MapKit

• SpringboardUIServices

• AccessibilityBundles

• Music

Known Issue

When viewed in the Simulator, the “Hybrid” view in Maps and MapKit apps does not show all of the tiles.

Fixed in beta 5

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.

Fixed in beta 5

The Music app may stop responding when downloading an album.

Note

The schedule and intended use of MARKDOWN_HASH2339c5e2c1b31dbe70863255ff4e4780MARKDOWN_HASH 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 MARKDOWN_HASH5e3ef3a8307d02868792fe7fce1440a0MARKDOWN_HASH. Widgets should NOT block returning from MARKDOWN_HASHccb1b53734ed32a08ab806ba2aa0be32MARKDOWN_HASH on the results of this operation. Instead, widgets should load cached state inMARKDOWN_HASH2de53c1a80e409919892558ffea6671dMARKDOWN_HASH in order to match the state of the view from the last MARKDOWN_HASH24d2419b8033dc4fd62ad355279af9b9MARKDOWN_HASH, then transition smoothly to the new data when it arrives.

Note

Beginning in iOS 8 beta 2, the MARKDOWN_HASH01eff6314d2cbdbabcbe503d2b7f96bcMARKDOWN_HASH class provides a new “priority” property with three associated constants: MARKDOWN_HASHc44ec0a1dd4e62ff0ca3be633d20c769MARKDOWN_HASH,MARKDOWN_HASH6e0af54bc2f033640108dbb32b390d5cMARKDOWN_HASH, and MARKDOWN_HASHf4b1c15ae87bd03c20629b33bf23929dMARKDOWN_HASH. MARKDOWN_HASHe43ec4d582461cd1770da977a28afcdbMARKDOWN_HASH 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 MARKDOWN_HASHe43ec4d582461cd1770da977a28afcdbMARKDOWN_HASH performance.

For complete usage details of MARKDOWN_HASHe43ec4d582461cd1770da977a28afcdbMARKDOWN_HASH priorities, refer to the MARKDOWN_HASHf11f83ad6ca9dac65a3e13ec31f675baMARKDOWN_HASH header file, which is provided by the Foundation framework.

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.

Notes

• iCloud Photo Library requires beta 3 or later.

• 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.

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.

Known Issue

PDF files may not display in some applications.

Notes

• 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.

Known Issue

Some icons are missing in Settings and only appear after the row is tapped.

Known Issue

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

Workaround: Some accounts may have an extra long lag. Wait a couple of minutes and they should complete.

Known Issue

Calling contacts with Siri is supported only on devices with the latest developer seed build. Prior developer seed builds no longer support this feature.

Fixed in beta 5

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.

Known Issue

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

Notes

• MARKDOWN_HASHa4afb21925d0fac81e0197a0f9723d8dMARKDOWN_HASH has a default value of YES for MARKDOWN_HASHcbd8bd780a0e600326ef7fad08bd2f44MARKDOWN_HASH. This differs from the normal MARKDOWN_HASHd2de326beb65fda155908c2388bcda33MARKDOWN_HASH default of NO.

• MARKDOWN_HASH72a9fb05b5d7d628d955cd98c55b0bacMARKDOWN_HASH and MARKDOWN_HASHabf8af6bfa5b2308f92c815d30a7ab13MARKDOWN_HASH API have been removed. Please use the MARKDOWN_HASH922ae0c0c4d095695fd0dba6126a6c2eMARKDOWN_HASH property instead.

Fixed in beta 5

When the width of a multiline label changes due to changes in the MARKDOWN_HASH922ae0c0c4d095695fd0dba6126a6c2eMARKDOWN_HASH of some view, the intrinsic content size of the label is not invalidated when it should be. As a result the layout can unexpectedly truncate the label (or text view).

Workaround: The view whose MARKDOWN_HASH922ae0c0c4d095695fd0dba6126a6c2eMARKDOWN_HASH are changing should override MARKDOWN_HASH6757fc5080fa7f8de7d7b8222ed20617MARKDOWN_HASH and send MARKDOWN_HASHfc727fae0f2d099edd4f6922a4b5a857MARKDOWN_HASH to the label.

Known Issue

To use an action sheet-style MARKDOWN_HASHb2687101ee05a40c51739427eea85d34MARKDOWN_HASH on iPad, the sourceView of the alert controller’s popoverPresentationController must be set.

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.

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.

• The MARKDOWN_HASH252ec854eac5bf9a864d88270ce31b80MARKDOWN_HASH viewport property is no longer supported in iOS 8.

Known Issue

The MARKDOWN_HASHc510d5a3d97cb2f599576a56b2703434MARKDOWN_HASH and MARKDOWN_HASH4260c01394765a497287987f27d6823aMARKDOWN_HASH DOM properties always return 0. Other DOM properties will need to be used instead. This may affect websites that use leaf.js.
