Apple、iOS 10 beta 2［Build：14A5297c］を開発者に公開！

Appleが、iOS 10 beta 2［Build：14A5297c］を開発者に公開しちています。リリースノートには、以下の多数の修正が記載されています。

Functionality not in iOS 10 beta 2
• Faces in the Photos app do not sync across your devices.
• Functionality that requires adoption from App Store apps, such as iMessage apps, SiriKit, and
Maps extensions, will not be available until those apps are able to adopt and submit to the Store.

Fixed in this release
AdSupport framework
Vendor and advertising identifiers may change after upgrading to iOS 10 beta 1.
AirPlay
Attempting to mirror a device running iOS 10 to an Apple TV via AirPlay may fail.
Apple Pay
• Initiating an Apple Pay transaction in Safari on a Mac displays an empty payment sheet if Apple
Pay hasn’t been set up on your iPhone.
• Apple Pay payment sheet fields cannot be accessed if a payment request fails due to a server
connection or a TouchID/passcode error.
• The shipping method displays as <?> with garbage data if the shipping method is set to None
and the shipping address is required.
Apple Pencil
When drawing in from the edge of iPad with Apple Pencil, reported tilt and azimuth angles may
occasionally have large errors. In these cases, the angles are always reported as estimated.
AppleID Login
Some accounts with two-factor authentication enabled may not be able to log in using a verification
code sent to another device.
AVFoundation Capture
• Capture of raw images occasionally fails on iPhone SE.
• Live Photo movies are not delivered when capturing with AVCapturePhotoOutput.
Backup
• Users may not be able to restore from iCloud backups created on iOS 8 and earlier. Users will be
presented with a dialog box displaying the error “Cannot Restore Backup.”
• When restoring from an iCloud backup, some accounts may take a few minutes to display the list
of backups.
CFNetwork HTTPProtocol
Apps that use UIWebView and also implement NSURLProtocol subclasses that block threads, will
experience NSURLSession and NSURLConenction load delays.
CFNetwork Session
You may see an issue where checking for a software update in tvOS results in the error “The update was
not successful.” If a second attempt is unsuccessful, please file a bug indicating the time of the issue and
your local network setup.
Additionally, NSURLSession background transfers that use HTTP/2 or SPDY may cause inefficient use of
TCP connections, such that subsequent requests (which may use HTTP/1.1) could be delayed up to one
minute per TCP connection before they can start. System services may also be similarly impacted.
CloudKit
Saving a child record with its parent property set to nil can sometimes fail.
Contacts
After creating a new contact, tapping Cancel does not exit the contact card.
Exchange Account Setup
Adding an Exchange account either manually or via configuration profile may fail, resulting in a state
where the account is visible in Settings, but data does not sync.
FaceTime
Once removed, FaceTime cannot be restored on iPad or iPod touch.
Guided Access
You cannot exit Guided Access after enabling it while using an app.
HomeKit
HomeKit may be unable to synchronize and an “Enable Keychain” dialog is displayed even though iCloud
Keychain is already enabled.
iBooks
If you select an unpurchased book when viewing a series on your bookshelf and then attempt to
download the sample from the product page, iBooks will crash.

• Some embedded images in the Twitter app appear low-resolution.
• Saving optimized images using kCGImageDestinationOptimizeColorForSharing
is not available in iOS 10 beta 1.
Keyboards
• In Spotlight, when typing in Chinese or Japanese with hardware keyboards, the candidate bar is
not in a fixed position.
• Text replacements created on iOS 10 beta 1 might be lost after updating to subsequent iOS 10
betas.
Lock Screen
• Scrolling horizontally on the lock screen may be difficult or not work (touch input can be blocked
by lock screen elements such as Music controls and album art).
• Sliding up on the Continuity icon (bottom left corner) does not work.
Messages
• When Messages extensions are in edit mode, it can take multiple attempts to delete by tapping
on the “X.”
• Occasionally, when third party Messages extensions insert a message bubble, the bubble appears
blank.
• Tapping on a sticker while a sticker pack app is in expanded view does not stage the sticker.
• Stickers peeled off and dropped back in the browser disappear.
• Calling dismiss on an expanded MSMessagesAppViewController changes the presentation
style to .compact instead of dismissing the controller. Calling dismiss when the controller is
already in compact mode dismisses the controller.
• When inspecting an incoming third party message, the senderParticipantIdentifier
property of selectedMessage is nil.
