Displaying activity indicator on WKWebView using swift

Question

I am working on the following code and trying to show an activity indicator in the view whilst the page is loading..

I tried to implement the WKNavigationDelegate methods but I am failing as nothing shows.

Any suggestions on how to fix this?

I am not setting the SupportWebView view delegate anywhere but I wouldn't know how to do it in swift..

import UIKit import WebKit  class SupportWebView: UIViewController, WKNavigationDelegate {     @IBOutlet var containerView : UIView? = nil      var webView: WKWebView?      override func loadView() {         super.loadView()         self.webView = WKWebView()         self.view = self.webView     }      override func viewDidLoad() {         super.viewDidLoad()          var dataManager = DataManager.sharedDataManager()         var url = dataManager.myValidURL         var req = NSURLRequest(URL:url!)         self.webView!.loadRequest(req)     }      override func didReceiveMemoryWarning() {         super.didReceiveMemoryWarning()         // Dispose of any resources that can be recreated.     }      func webView(webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {         UIApplication.sharedApplication().networkActivityIndicatorVisible = true     }       func webView(webView: WKWebView, didFinishNavigation navigation: WKNavigation!) {         UIApplication.sharedApplication().networkActivityIndicatorVisible = false     } }

As commented, you forgot to set the webView delegate:

override func loadView() {     super.loadView()     self.webView = WKWebView()     self.webView.navigationDelegate = self     self.view = self.webView }
