Answer 1

First of all you need to implement the required WKUIDelegate methods, in your case you need to implement:

optional func webView(_ webView: WKWebView, 
    runJavaScriptAlertPanelWithMessage message: String, 
         initiatedByFrame frame: WKFrameInfo, 
        completionHandler: @escaping () -> Void)
{
    // parameter **message** will hold your actual alert message.

    // Write Your Customised code to display the alert message
}
