AVURLResourceLoaderDelegate custom urls do not work in the iOS 11.0b1 simulator.

Attempting to use a custom URL with AVURLResourceLoaderDelegate returns error messages like:

AVARLDelegateDemo[4006:287820] [] <<<< Async >>>> playerasync_runAsynchronousCommandOnQueue: Command 3 returned -12784; this async error will be discarded

More detailed error messages from my real app:

Steps to Reproduce:
Install and run AVARLDelegateDemo from
https://developer.apple.com/library/content/samplecode/sc1791/Introduction/Intro.html

Expected Results:
Expect the demo to work on Xcode 9.0b1 with the iOS 11.0b1 simulator

Observed Results:
The demo does not work when run on Xcode 9.0b1 with the iOS 11.0b1 simulator

AVARLDelegateDemo[4006:287820] [] <<<< Async >>>> playerasync_runAsynchronousCommandOnQueue: Command 3 returned -12784; this async error will be discarded

Notes:
The demo works when run on real hardware running iOS 11.0b1, such as an iPhone 7s Plus
The demo works when run on the Xcode 9.0b1 simulator running earlier versions of iOS such as 8.4
