Many thanks Francis for the useful info!
Have also managed to build and run on my Iphone 6S Plus (iOS 14) using XCode 12.2.
Findings:
I confirm the issue with the sound, there is no sound at all. I also see the following msg:
No HRTFs found
HRTF not enabled!
The videos also just show for an instance and then disappear, perhaps also due to this HRTF issue?

Other errors:
[NSError init] called; this results in an invalid NSError instance. It will raise an exception in a future release. Please call errorWithDomain:code:userInfo: or initWithDomain:code:userInfo:. This message shown only once.
Warnings (not sure if they affect anything):
[450:28038] [Metal Compiler Warning] Warning: Compilation succeeded with:
