watchOS 4 beta 2はバグの修正が中心でリリースノートは以下の通りです。

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)
• ApplicationsthatuseCKModifyRecordsOperationshouldspecifyanappropriate 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 MediaResolved Issues• Haptics now play for frontmost apps. (32139107)DictationKnown Issues• Some languages are not available for Dictation on watchOS, including the newly released Shanghainese dictation. (32235495)Foundation

  New Features

• AddedaschedulingAPItoURLSessionTaskthatallowsbackgroundURLSession 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)
• AddedanAdaptableConnectivityAPItoURLSessionthatenablestaskstoautomatically 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)
• Attempting to finish a workout route when no location data is inserted no longer throws an exception. (32307523)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)HomeKitResolved Issues• Location-based automation triggers now work if triggered from the alert on Apple Watch. (32288709)MessagesKnown Issues

  • Messages may fail to send when responding to Activity notifications. (32294875)

• Alarms are lost when migrating to watchOS 4. (31285349)SettingsResolved Issues
