Breathe
Resolved Issues
• Breathe notification preferences are now respected. (32298347)
CloudKit
Known Issues
• CloudKit does not support unsigned long long values with the high-order bit set.
(30567424)
• Applications that use CKModifyRecordsOperation should specify an appropriate
value for CKModifyRecordsOperation.isAtomic. If your client is compiled against
watchOS 4, operations enqueued against the default CKRecordZone have new behavior
because atomic is true by default. If the operation hits a "preflight" failure (most
commonly, a network issue uploading a CKAsset, or a malformed CKRecord), the entire
operation is canceled. (30838858)
Core Media
Resolved Issues
• Haptics now play for frontmost apps. (32139107)
Dictation
Known Issues
• Some languages are not available for Dictation on watchOS, including the newly released
Shanghainese dictation. (32235495)
Foundation
New Features
• Added a scheduling API to URLSessionTask that allows background URLSession
clients to schedule tasks in the future, enabling easy background app refresh semantics
for apps, watchOS complications, and more. The API also allows developers to update
requests before transmission to address cases where the request has become stale when
scheduled in the future. Additions include the earliestBeginDate,
countOfBytesClientExpectsToSend, and
countOfBytesClientExpectsToReceive properties of URSessionTask, and the
URLSession:task:willBeginDelayedRequest:completionHandler method
of URLSessionTaskDelegate protocol. (27866330)
• URLSessionTask adopts the ProgressReporting protocol providing a consistent
mechanism for URLSession clients to track the progress of URLSessionTask using
the new progress property. (30834550)
• Added an Adaptable Connectivity API to URLSession that enables tasks to automatically
monitor and wait for satisfactory network connectivity, instead of immediately failing with
an error when connectivity is unsatisfactory. Additions include the
waitsForConnectivity property of URLSessionConfiguration and the

URLSession:taskIsWaitingForConnectivity: method of the
URLSessionTaskDelegate protocol.
• Added support for HTTP brotli content encoding to URLSession. By defaueslt, HTTP
requests contain a br value (in addition to gzip and deflate) for the Accept-Encoding
HTTP header, informing the web server that the user agent supports brotli encoding. The
web server can send an HTTP body with Content-Encoding: br in the HTTP header
to indicate that the content is brotli-encoded. URLSession automatically decompresses
the HTTP body data and pass the decoded data back to the client in the same way it does
for Content-Encoding: gzip. For binary compatibility reasons, URLSession brotli
support is enabled only for apps built using the watchOS 4 SDK. (27724985)
HealthKit
Resolved Issues
• Pressing the Side Button and Digital Crown pauses an active workout session even if the
the app is not in the foreground. (30199786)

Known Issues
• To track location in the background while a user is in a workout session, add
UIBackgroundModes/location in the Info.plist file. (29483437)
HomeKit

• Music tracks now play from and sync to Apple Watch. (32314271)

• Apple Watch must be on its charger for Music tracks to sync. (31818127)
• Deleting a playlist or album in the Apple Watch app will cause the app to crash and your
selection will remain on your Apple Watch. (32624529)
• Love and Dislike options are missing for locally synced music on Apple Watch.
