title: Get reference of SKLabelNode from SKScene
body: <p>I am trying to get a reference to <code>SKLabelNode</code>. Any ideas?</p>
  
  <p>I tried doing like this:</p>
  
  <pre><code> let score = 10
   let label = SKLabelNode(fileNamed: "ScoreLabel")
   override func didMove(to view: SKView) {
   label.text = score
  }
  </code></pre>
  
  <p>The text does not change to 10, it stays on 0 as default on <code>SKScene</code>.</p>
