title: UIProgressView - Progress Bar - SpriteKit / Swift
body: <p>I'm hoping to use a <code>progress bar</code> to denote a percentage in my App.</p>
  
  <p>I'm actually building it in Spritekit using Swift, so I'm hoping to do it programmatically, without the use of a storyboard etc.</p>
  
  <p>I found <a href="http://rshankar.com/swift-demo-add-progress-bar/" rel="nofollow">this awesome tutorial</a>, but unfortunately I can't seem to add it to my <code>GameScene</code>/ worldNode...</p>
  
  <p>How can I create a progress bar and add it to my GameScene, inside my SKView/Gamescene (not via ViewController)?</p>
