I am experiencing an issue with my app, which includes a WKWebView used for displaying and playing WebRTC content (audio and video). Everything works fine on macOS, but on iOS 18, while the video is displayed correctly, there is no sound. I am wondering if this could be related to privacy permissions on iOS. Could you please clarify if there are any specific privacy permissions I need to address?
I would like to confirm:
- AVAudioSession.sharedInstance().setCategory requires any special configuration for WebRTC audio. Are there any particular settings needed for this? My setting codes are below:
try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default, policy: .longFormAudio)
- Do the JavaScript codes in the HTML file require any special handling to ensure WebRTC audio works properly on iOS?
const audioRender = document.createElement('audio');
audioRender.id = 'xxxid';
audioRender.srcObject = streamSource;
audioRender.autoplay = true;
audioHolder.appendChild(audioRender);
- Does WKWebViewConfiguration need any specific parameter adjustments to ensure audio playback in WebRTC works as expected?
let webViewConfiguration = WKWebViewConfiguration()
let contentController = WKUserContentController()
contentController.add(self, name: "***")
webViewConfiguration.userContentController = contentController
webViewConfiguration.allowsInlineMediaPlayback = true
