For sake of example, let's say its google.com. @IBOutlet var website: UIWebView! var url = "http://www.google.com" func loadUrl() { let requestURL = NSURL(string: url) let request = NSURLRequest(URL: requestURL!) website.loadRequest(request) } override func viewDidLoad() { super.viewDidLoad() website.delegate = self loadUrl() } func
