3rd Party Apps

New Issues

  • Signing into the Sling TV app does not work. (32829340)
  • When initiating video playback using the Plex app, you may need to press Play/Pause on the Apple TV Remote for the video to begin playing. (32662888)

    Known Issues

    • DirectTV Now may crash on launch. (29533442)

    CloudKit

    Known Issues

• ApplicationsthatuseCloudKit’sCKModifyRecordsOperationshouldspecifyan appropriate value for CKModifyRecordsOperation -> atomic. If your client is compiled against watchOS 4, operations enqueued against the default CKRecordZone have new behavior when atomic = YES (and this is the default value for this property): 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)

• CloudKitdoesnotsupportunsignedlonglongnumbersasvaluesforaCKRecord, if the number’s high-order bit is set. Beginning in this seed, setting such a value throws an exception. (30567424)

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 default, 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 passes 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 tvOS 11 SDK. (27724985)

  • When installing an HTTP Proxy Payload with no credentials and then entering a username and password at a later time when prompted, the correct credentials are not accepted as valid. (32360765)

  • When setting management on an Apple TV to skip all setup panes, the TV Provider setup pane may appear. (31766460)
  • A device that is manually enrolled in the Device Enrollment Program or Apple School Manager may display an on-screen message “This device is provisionally enrolled in DEP. You can remove it from DEP by erasing it in Settings.” (32023738)
