title: How do I get SpriteKit Playgrounds working in Xcode 8 beta?
body: <p>I want to be able to easily prototype my Sprite Kit code in Playgrounds.
  This works fine in Xcode 7</p>
  
  <pre><code>import UIKit
  import SpriteKit
  import XCPlayground
  
  
  let sceneView = SKView(frame: CGRect(x:0 , y:0, width: 480, height: 320))
  
  let scene = SKScene(size: CGSize(width: 480, height: 320))
  sceneView.showsFPS = true
  sceneView.presentScene(scene)
  XCPlaygroundPage.currentPage.liveView = sceneView
  
  let square = SKSpriteNode(imageNamed: "square")
  square.name = "shape"
  square.position = CGPoint(x: scene.size.width * 0.25, y: scene.size.height * 0.5)
  
  let circle = SKSpriteNode(imageNamed: "circle")
  circle.name = "shape"
  circle.position = CGPoint(x: scene.size.width * 0.50, y: scene.size.height * 0.5)
  
  let triangle = SKSpriteNode(imageNamed: "triangle")
  triangle.name = "shape"
  triangle.position = CGPoint(x: scene.size.width * 0.75, y: scene.size.height * 0.5)
  
  scene.addChild(square)
  scene.addChild(circle)
  scene.addChild(triangle)
  </code></pre>
  
  <p>In Xcode 7 I get a nice live view as such

  <p>This just doesn't work in Swift 3 and Version 8.0 beta 3 (8S174q).
  What do I have to change? </p>
