title: Add gesture to SKShapeNode in WatchOS3
body: <p>I am able to add gesture in <code>SpriteKit</code> Scene. But not able to add gesture to one of my node in the scene. </p>
  
  <p>Also, <code>touchesBegan</code> method is not available in <code>WatchKit</code>. So added gestureRecognizer in my interface and pass it in the SpriteKit Scene. </p>
  
  <p>But this lead to add panGesture to the whole scene instead of my node. </p>
  
  <p><strong>Is there any way to add the gesture to only one of my node?</strong></p>
