EXC_BREAKPOINT when using VideoRendererView and Swift 6

[reddavis]

What did you do?

i've been experimenting with Stream for video calling.

one thing that will be

important for us is the ability to roll our own custom UI.

i've been playing around with something super basic

1. setting up a StreamVideo using the test credentials provided in the docs
2. creating a call
3. joining the call
4. using VideoRendererView to display the participants

What did you expect to happen?

the VideoRendererView's to render the video.

What happened instead?

EXC_BREAKPOINT (code=1, subcode=0x1016e2f18)
VideoRendererView 
line: 149

after some poking around, i found that this crash only happens when Swift 6 is chosen.

it works fine on Swift 5.

i've attached a demo project.

if you build on Swift 6, you'll get the crash, but when you build with Swift 5 it'll work.

Hey @reddavis,

Thanks for reaching out with this issue. You are absolutely and unfortunately - even though we have started the Swift 6 migration on our side - we haven't completed it.

It's now one of our priorities so you can expect that fixed in the following releases.

I'm sorry for the inconvenience and I'm glad that there is a workaround for now, while we finalise the migration.

Best regards,
Ilias
