I try to use spriteKit to show something in playground in assistant editor. However, nothing showed. Below is the code. And if any one can show the results (a blue rectangle), please inform me. If not, please figure out where the problem is.
import UIKit import SpriteKit let view:SKView = SKView(frame: CGRectMake(0, 0, 1000, 800)) let scene:SKScene = SKScene(size: CGSizeMake(1000, 800)) scene.scaleMode = SKSceneScaleMode.AspectFit let blueBox: SKSpriteNode = SKSpriteNode(color: UIColor.blueColor(), size: CGSizeMake(300, 300)) blueBox.position = CGPointMake(512, 384) scene.addChild(blueBox) view.presentScene(scene)
You can see the current state of a view by clicking the QuickLook (eye) or circled-plus button in the sidebar. But to see your SpriteKit scene animate, you probably want a live view. For that, you need the XCPlayground framework.
import XCPlayground XCPShowView("my SpriteKit view", view)
