MARK:-wkuidelegate//monitoring via JS call warning box func WebView (_ Webview:wkwebview, runjavascriptalertpanelwithmessage mes Sage:string, Initiatedbyframe frame:wkframeinfo, Completionhandler: @escaping (), Void) {Let alert = Uialer  Tcontroller (Title:nil, Message:message, Preferredstyle:. Alert) Alert.addaction (uialertaction (title: "OK", style: . Default, Handler: {(action) in Completionhandler ()})) Self.present (alert, animated:true, com PLETION:NIL)}//Listen through JS call Prompt box Func WebView (_ Webview:wkwebview, Runjavascriptconfirmpanelwithmessage messag E:string, Initiatedbyframe frame:wkframeinfo, Completionhandler: @escaping (Bool), Void) {Let alert = Uiale Rtcontroller (Title:nil, Message:message, Preferredstyle:. Alert) Alert.addaction (uialertaction (title: "OK", style :. Default, Handler: {(action) in Completionhandler (True)})) Alert.addaction (Uialertaction (titl E: "Cancel", Style:. defAult, Handler: {(action) in Completionhandler (False)})) Self.present (alert, animated:true, com  PLETION:NIL)}//Listen JS call input box func WebView (_ Webview:wkwebview, Runjavascripttextinputpanelwithprompt prompt:        String, defaulttext:string, Initiatedbyframe frame:wkframeinfo, Completionhandler: @escaping (String), Void) { Similar to the above two methods}
