tvOS SDK Release Notes for tvOS 9.1



The tvOS SDK leverages many of the same frameworks and technologies that you’re already familiar using for iOS development. However, please note that all libraries and frameworks used in your tvOS apps must be built for tvOS, including any 3rd-party libraries. Do not link your tvOS app against frameworks or libraries that are not built with tvOS. Attempting to do so will result in a build failure. Furthermore, bitcode is now required for all tvOS apps. All apps and frameworks in the app bundle must include bitcode.

tvOS SDK 9.1 provides support for developing tvOS apps. It’s packaged with a complete set of Xcode tools, compilers, and frameworks for creating apps for tvOS. These tools include the Xcode IDE and the Instruments analysis tool, among many others.

This version of tvOS is intended for installation only on devices registered with the Apple Developer Program. Attempting to install this version of tvOS in an unauthorized manner could put your device in an unusable state.

Notes and Known Issues


Known Issue

On tvOS, AVPlayerViewController automatically resumes playback when video playback stalls. This behavior prevents clients from programmatically pausing playback, as a programmatic pause will appear to be a stall and playback will immediately resume. A future update to allow application control of the autoresume behavior is planned. In the meantime, please file a bug at describing your use case in detail.



  • Explicit Congestion Notification (ECN) is now enabled by default on Ethernet and Wi-Fi. This is designed to reduce network delays and reduce packet loss.

  • The ability to synthesize NAT64 IPv6 addresses from IPv4 literals was added to getaddrinfo.

Known Issue

When using the beginAccessingResourcesWithCompletionHandler: method, any resource that has already been downloaded will report a progress of 0.0 even though it is available locally.


Known Issue

When a scroll view is scrolled due to a focus change, the run loop mode will be set to UITrackingRunLoopMode. When the scrolling ends, the mode will return to the default mode. This is a change from past behavior: Previously, the run loop mode would not change.
