title: MBProgressBarHUD not appearing with swift and iOS8
body: <p>I'm trying to use MBProgressHUD (<a href="https://github.com/jdg/MBProgressHUD" rel="nofollow">https://github.com/jdg/MBProgressHUD</a>) and was able to get it working with my Podfile.  However, now the hud does not appear.  Has anyone been able to successfully get this working with swift?</p>
  
  <p>Podfile</p>
  
  <pre><code>platform :ios, '8.0'
  pod 'AFNetworking'
  pod 'MBProgressHUD', '~&gt; 0.8'
  </code></pre>
  
  <p>MovieDetailViewController.swift </p>
  
  <pre><code>override func viewDidLoad() {
      super.viewDidLoad() // Do any additional setup after loading the view.
      var url: String = "http://api.rottentomatoes.com/api/public/v1.0/movies/"+movieID!+".json?apikey="+apiKey
      NSLog("url = \(url)")
      var request = NSURLRequest(URL: NSURL(string: url))
  
      // setup HUD; https://github.com/jdg/MBProgressHUD
      var hud = MBProgressHUD()
      hud.show(true)
  
      NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue() )     
      {
          (response: NSURLResponse!, data: NSData!, error: NSError!) -&gt; Void in
  
          var err: NSError?
          var object = NSJSONSerialization.JSONObjectWithData(data, options: nil, error: &amp;err) as NSDictionary
  
          if let yearInt = object["year"] as? Int {
              self.year.text = String(yearInt)
          }
          self.title = object["title"] as? String
          self.movieTitle.text = self.title
  
          self.synopsis.text = object["synopsis"] as? String
          self.mpaaRating.text = object["mpaa_rating"] as? String
          var ratings = object["ratings"] as NSDictionary
          var posters = object["posters"] as NSDictionary
  
          // setup background picture
          var posterUrl = posters["thumbnail"] as String
          var image = UIImageView()
          image.setImageWithURL(NSURL(string: posterUrl))
          image.contentMode = UIViewContentMode.ScaleAspectFill
          self.scrollView.backgroundColor = UIColor.clearColor()
          self.scrollView.addSubview(image)
  
          // stop the hud
          hud.hide(true)
      }
  
  }
