Apple Releases tvOS 9.1 Beta 2 to Developers

Apple released another round of betas today, making it seem like they’re now on a weekly cycle. tvOS 9.1 will be the first update to tvOS since its debut last month with the new Apple TV.

Of course, Apple has always released Apple TV beta software to developers, despite never having an App Store before. It would always come alongside iOS betas and it would just be called Apple TV beta. The funny thing is that Apple TV betas would always be a version behind. For example, the third generation Apple TV’s last update came alongside iOS 8.3, so it was Apple TV 7.3. I have no idea how they got to tvOS 9.

tvOS 9.1 Beta 2 came alongside iOS 9.2 Beta 3 and Mac OS X 10.11.2 El Capitan Beta 3.

tvOS 9.1 Beta 2 Release Notes

Introduction

The tvOS SDK leverages many of the same frameworks and technologies that you’re already 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 beta 3 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.

Bug Reporting

For issues not mentioned in the Notes and Known Issues section, please file bugs through the Apple Developer website https://developer.apple.com/bug-reporting/. Additionally, you may discuss these issues and tvOS SDK 9.1 in the Apple Developer Forums at https://forums.developer.apple.com/ community/pre-release/tvos-beta.

Autosubmission of Diagnostic and Usage Data

By default, the tvOS 9.1 beta automatically sends anonymous diagnostic and usage data back to Apple. This includes information about crashes, freezes, kernel panics, and how you use Apple and third-party software, hardware, and services. This information is used to help Apple improve the quality and performance of its products and services. You can stop autosubmission of diagnostics and usage data by going to Settings > General > Privacy > Send To Apple > Off.

Notes and Known Issues

AVKit

Known Issue

On tvOS, AVPlayerViewController automatically resumes playback when video playback stalls. This will prevent 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  https://developer.apple.com/bugreporting/ describing your use case in detail.

Networking

Notes

  • 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.

On-Demand Resources

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.

Remote

Known Issue

If the remote sleeps in Simulator, motion control will no longer work when it wakes back up.Workaround: Restart the app.

Setup

Known Issue

After reading the tvOS Terms and Conditions, press MENU to return to the App Analytics screen. Then press Continue and then Accept to complete setup.

StoreKit

Note

StoreKit (that is, In-App Purchase) does not work in Simulator.

UIKit

Note

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.
