title: Detect UIImageView Touch in Swift
body: <p>How would you detect and run an action when a <code>UIImageView</code> is touched? 
  This is the code that I have so far:</p>
  
  <pre><code>override func touchesBegan(touches: Set&lt;NSObject&gt;, withEvent event: UIEvent) { 
      var touch: UITouch = UITouch()
      if touch.view == profileImage {
          println("image touched")
      }
  }
  </code></pre>
