Swift WKWebView webViewDidClose(window.close()) not working - swift

Question

I have a WKWebView
after moving several pages, web do confirm action.
like this:
var Common = {
Close : function (){
if(confirm("confirm?")) window.close();
}
}
in my code:
webView.uiDelegate = self
func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
// this method is not invoked
}
func webViewDidClose(_ webView: WKWebView) {
dismiss(animated: true, completion: nil)
}
func webView(_ webView: WKWebView, runJavaScriptConfirmPanelWithMessage message: String, initiatedByFrame frame: WKFrameInfo, completionHandler: #escaping (Bool) -> Void) {
// this method invoked
let alertController = UIAlertController(title: message, message: nil, preferredStyle: .alert);
let cancelAction = UIAlertAction(title: "cancel", style: .cancel) {
_ in completionHandler(false)
}
let okAction = UIAlertAction(title: "ok", style: .default) {
_ in completionHandler(true)
}
alertController.addAction(cancelAction)
alertController.addAction(okAction)
DispatchQueue.main.async {
self.present(alertController, animated: true, completion: nil)
}
}
in my alertController I called completionHandler(true). but webViewDidClose is not invoked. so I can not dismiss web vc.
what is the problem?
What can I try?

Answer 1

// webView.load(URLRequest)
webView.evaluateJavaScript("window.open(\"\(url.absoluteString)\");", completionHandler: { result, error in
})
override func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
if let currentWebView = createWebView {
currentWebView.load(navigationAction.request)
return nil
}
createWebView = WKWebView(frame: view.bounds, configuration: configuration)
createWebView!.navigationDelegate = self
createWebView!.uiDelegate = self
view.addSubview(createWebView!)
return createWebView!
}
