Question

  override func loadView() {
     let configuration = WKWebViewConfiguration()
     let controller = WKUserContentController()
     configuration.userContentController = controller

     let webView = WKWebView(frame: CGRect.zero, 
 configuration:configuration)


    // apply shim
    WKWebViewWebRTCShim(webView: webView, contentController: 
controller);




    let request = NSURLRequest(url: 
NSURL(string:"https://www.google.com")! as URL)
    webView.load(request as URLRequest)



    super.loadView()
    view.addSubview(webView)


    }

我是stackoverflow的新手，我正在开发具有WKWebViewWebRTCShim实现的iOS应用，但是当我尝试对其进行调试时，出现此错误。我认为所有框架都实现得很好。此代码有问题吗？

这是堆栈
