title: Blur effect on Image View is not working in iOS swift?
body: <p>Here is my code:</p>
  
  <pre><code>func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -&gt; UITableViewCell{
       let cell:TableViewCell = tableView.dequeueReusableCellWithIdentifier("TracksCellTracksView") as! TableViewCell
  
       self.addBlurEffect()
  
       return cell
   }
  
   func addBlur effect() {
      let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.ExtraLight)
      let blurEffectView = UIVisualEffectView(effect: blurEffect)
      blurEffectView.frame = albumArt!.bounds
      blurEffectView.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
      albumArt!.addSubview(blurEffectView)
  }
  </code></pre>
  
  <p>This code is not working; Please tell me some alternative way to do it.</p>
  
  <p>For info, I'm using constraints for ImageView.</p>
