title: camera's node name not visible in statistics
body: <p>I attached a name property to my camera node. The camera is fully functional and does its job.</p>
  
  <pre><code>let cameraNode = SCNNode()
  cameraNode.name = "I am camera"
  cameraNode.camera = SCNCamera()
  ...
  </code></pre>
  
  <p>The documentation states the following:</p>
  
  <blockquote>
    <p>The SceneKit statistics view (see showsStatistics) also shows the
    names of nodes with attached cameras.</p>
  </blockquote>
  
  <p>So I went to viewDidLoad and wrote:</p>
  
  <pre><code> sceneView.showsStatistics = true
  </code></pre>
  
  <p>However, in the simulator I only see this.<img src="https://i.stack.imgur.com/Dkox2.jpg" alt="enter image description here"></p>
  
  <p>Not sure what to expect, but shouldn't there be  a "I am camera" text somewhere? Where can I see the " I am camera" name?</p>
