title: How to add label to SCNNode?
body: <p>I’m trying to add a label to an SCNNode. So far I’ve managed to set a SKLabelNode as the material for the SCNNode. It sort of works, I can the SCNNode becomes the background colour of the SKLabelNode but I can’t see the text. Sometime I can see a red haze (the text colour is red) but no readable text.</p>
  
  <p>I also tried setting the material as a UIView and adding a UiLabel as a sub view. Again it sets as I can the whole SCNNode becomes the background colour of the UiLabel but I can’t see any text.</p>
  
  <pre><code>var block = SCNNode()
  var spriteScene = SKScene()
  var Lbl = SKLabelNode()
  
  lbl.text = “Hello World”
  
  lbl.color = blue (playground colour literal)
  lbl. = 2 //I tried various numbers
  lbl.fontColor = SKColor.red
  spriteScene.addChild(lbl)
  </code></pre>
