For iOS 14.3 apple announced WebRTC support for WKWebViews. For iOS 15, extension in such support was announced. I have loaded a WebView in both, iOS 14.5 and iOS 15 and observed different behaviors. Things do not work for either iOS. My website, requires access to the microphone. When I load it for iOS 14.5, and click on the microphone, the app crashes with a memory exception (Malloc) for webkit userPermissionRequestProxy. When I use iOS 15, no error or crash occurs, yet the microphone is not working. I have updated the info.plist file to allow permissions I am giving access to AVAudioSession. Is there anything else I need to do?
