title: Swift 2: check for type of touch in touchesBegan
body: <p>In Swift 2 I have the <code>touchesBegan</code> method with <code>Set&lt;UITouch&gt;</code>. Now, in the method I would like to check whether it was a tap/touch, a 3D touch..</p>
  
  <p>I tried using <code>.phase</code> on the first <code>UITouch</code>, but that resulted in nothing. How would I check what kind of touch the user did?</p>
