如何让SpriteKit Playgrounds在Xcode 8 beta中运行？

Question

我希望能够在Playgrounds中轻松构建我的Sprite Kit代码原型.这在Xcode 7中工作正常

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)

在Xcode 7中,我得到了一个很好的实时视图

这在Swift 3和Version 8.0 beta 3(8S174q)中不起作用.我需要改变什么？

该XCPlayground模块已被替换为PlaygroundSupport:

import PlaygroundSupport
import SpriteKit

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)
PlaygroundSupport.PlaygroundPage.current.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)
