URL WebView Swift Xcode 7

我希望有人能够提供帮助，我也是Xcode的新手，并且一直在不懈地尝试在webview中执行以下URL，但运气不佳：

http://view.vzaar.com/5532785/player

下面是代码：

导入UIKit

类ViewController：UIViewController {

@IBOutlet weak var webView: UIWebView!

override func viewDidLoad() {
    super.viewDidLoad()
    let url = NSURL (string: "http://view.vzaar.com/5532785/player")
    let requestObj = NSURLRequest(URL: url!);
    webView.loadRequest(requestObj)
    // Do any additional setup after loading the view.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}

任何建议将不胜感激。
