WKWebView Authorization

I am would like open a website, using a password/username (basic)Authorization in a WKWebView.
To do that I use the method didReceiveAuthenticationChallenge.

import UIKit
import WebKit

class ViewController: UIViewController {

@IBOutlet weak var container: UIView!
var webView: WKWebView!

override func viewDidLoad() {
    super.viewDidLoad()
    webView = WKWebView()
    container.addSubview(webView)
    let urlStr = "https://vplan.bielefeld-marienschule.logoip.de/subst_002.htm"
    let url = NSURL(string: urlStr)!
    let request = NSURLRequest(url: url as URL)
    webView.load(request as URLRequest)
}
func webView(webView: WKWebView, didReceiveAuthenticationChallenge challenge: URLAuthenticationChallenge, completionHandler: (URLSession.AuthChallengeDisposition, URLCredential?) -> Void){
    if challenge.protectionSpace.host == "https://vplan.bielefeld-marienschule.logoip.de/subst_002.htm" {
        let userStr = "********"
        let passwordStr = "********"
        let credential = URLCredential(user: userStr, password: passwordStr, persistence: URLCredential.Persistence.forSession)
        challenge.sender?.use(credential, for: challenge)
        completionHandler(.useCredential, credential)
    }
}

override func viewDidAppear(_ animated: Bool) {
    let frame = CGRect(x: 0, y: 0, width: container.bounds.width, height: container.bounds.height)
    webView.frame = frame

But for some reason, it does not work.
Adding the code line 

completionHandler(URLSession.AuthChallengeDisposition.UseCredential, credential)

like in the description here: Authentication with WKWebView in Swift produced an error.
I have also tried to change the challenge.protectionSpace.host into vplan.bielefeld-marienschule.logoip.de:443 which is shown as the login adress in the Safari pop-up and into the IP-Adress of the server (93.206.31.253).

Hope you can help me. Thank You!

In your code, you have not set the navigation delegate of the web view to your controller.

Change the definition of your controller to:

class ViewController: UIViewController, WKNavigationDelegate

And after creating your web view, set the navigation delegate to your controller:

webView.navigationDelegate = self

Depending on if you are using Swift 3, you may need to change the signature of the method to webView(_:didReceive:completionHandler:).
