E2EE not working on iOS

[philbot9]

Hello,

Really good work on this. I'm continuously impressed how easy it is to get up and running and how well everything works. I came across my first issue today while trying out E2EE on iOS.

Describe the bug

E2EE does not seem to be working on iOS. I tried to use it in the example app. After enabling E2EE and pressing "Connect" I see no video (see screenshots) and when I go back to the PreJoinPage the app appears to be frozen. There are no errors in the logs as far as I can tell.

I am able connect successfully without E2EE.

To Reproduce

1. Install example app on iPhone using XCode.
2. Run npm start
3. Open the app on iPhone
4. Toggle 'Enable E2EE'
5. Enter 'E2EE Key' (I used topsecretkey)
6. Press 'Connect'

Expected behavior

I should join the room and see my own video as well as others.

Screenshots

[philbot9]

I tried to debug this issue in XCode today and I believe I've narrowed it down to this call in @livekit/react-native-webrtc:

https://github.com/livekit/react-native-webrtc/blob/master/ios/RCTWebRTC/WebRTCModule%2BRTCFrameCryptor.m#L80

I am hitting the breakpoint on line 79, but never the one on line 85. So whatever is going wrong may be happening inside of WebRTC's RTCFrameCryptor initWithFactory. It simply never returns and I don't see any errors either.

Hey @philbot9, can you try updating the WebRTC-SDK dependency in your podfile? I think I forgot to update the dependency here, so you might be on the previous version with the deadlock bug. Can check your current podfile.lock to see which WebRTC-SDK version it's using.

Example of changing the dependency version:

target 'YourReactNativeApp` do
  # ...
  pod 'WebRTC-SDK', '~>125.6422.07'
end
