}

/// in `WKNavigationDelegate` object
func webView(_ webView: WKWebView, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
    guard let alert = UIAlertController(for: challenge, completion: completionHandler) else {
        // Should call `completionHandler` if `alertForAuthentication` return `.None`.
        completionHandler(.performDefaultHandling, nil)
