title: Tap / Select Node in SceneKit (Swift)
body: <p>I'm new to SceneKit and 3D spaces in iOS. I'm currently working on a simple game that shows a cube of 28 segments ("mini cubes" if you want).</p>
  
  <p>I want to move the mini cubes by tapping them, but I can't get my head around how to select specific nodes (childnodes of the big cube).</p>
  
  <p>Can anybody help me or post a link to SceneKit tutorials for dummies? I've been looking for days now, and haven't found what I'm looking for.</p>
  
  <p>Cheers</p>
