Replay kit::documentation? examples?

i'm very interested in this kit to record audio and video while the user is using my app on the iPad.


But where is the documentation and examples??


there is nothing here


https://developer.apple.com/library/prerelease/ios/navigation/


or here


https://developer.apple.com/library/prerelease/ios/releasenotes/General/iOS90APIDiffs/modules/ReplayKit.html

As far as I checked, these are the only available docs or samples:

WWDC 15 Session video: Going Social with ReplayKit and Game Center

Sample code: DemoBots: Building a Cross Platform Game with SpriteKit and GameplayKit


With Command-clicking the relevant part of the above sample code, you can find some descriptions, but may not be sufficient.

I built DemoBots for iPad 1566 with iOS 9b3 but the replaykit doesn't appear to be working. i hit record button, it has the initial popup to allow video and microphone then played a game.


after that i checked iTunes, Video, Photos, Game Center and there is no video file.


at the Xcode console it throws


2015-07-11 12:52:02.340 DemoBots[476:373384] <CAMetalLayer: 0x1298345a0>: calling -display has no effect.
