Have the same issue, and have resolved. Here is my workaround: I am using objc to develop native app, without any third-party framework(react/flutter). I have tried these two config: myWkWebView.configuration.allowsInlineMediaPlayback = NO; myWkWebView.configuration.mediaTypesRequiringUserActionForPlayback = WKAudiovisualMediaTypeAll; but it is not work. Then, I figure out what the problem is. You need to set the configuration before initialize the WkWebview instance: WKWebViewConfiguration *config = [[WKWebViewConfiguration alloc] init]; config.allowsInlineMediaPlayback = YES; config.mediaTypesRequiringUserActionForPlayback = WKAudiovisualMediaTypeAll; id myWkWebView = [[WKWebView alloc] initWithFrame:CGRectMake(someX, someY, someWidth, someHeight) configuration:config];
