Apple hat am gestrigen Abend die zweite Beta von tvOS 11 für Entwickler freigegeben. Es ist das nächste große Release des Betriebssystems für den Apple TV 4.
Entwickler können ihren sich ab sofort das neueste Testrelease von tvOS 11 im Apple Developer Portal holen. Dazu muss das Apple Developer Profil auf der Streaming Box installiert werden. Ist das passiert erscheint das Update in den Systemeinstellungen.Hier die Änderungen von tvOS 11 Beta 2 im Detail:
General
New Features
• Added AVRoutePickerView to the AVKit framework and AVRouteDetector to the
AVFoundation framework for enabling users to choose the route for playing content
when multiple routes are available. Use AVRouteDetector to determine if multiple
routes are available when route detection is enabled. If multiple routes are available, use
AVRoutePickerView to present an interface for the user to choose the routes.
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
• Applications that use CloudKit's CKModifyRecordsOperation should specify an
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)

• CloudKit does not support unsigned long long numbers as values for a CKRecord,
if the number’s high-order bit is set. Beginning in this seed, setting such a value throws
an exception. (30567424)
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 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)
