我找不到解决问题的方法,也许我没有正确实施。当我运行它时,我只是得到一个空白的白色屏幕。我尝试过在本网站上看到过的不同方法,但都没有。错误突出显示在" fatalError(" init(编码器:)尚未实现")"。有什么明显的东西我不见了吗?

我刚刚在Playground测试了你的代码并添加了一些内容,并且它运行正常。检查this。
import SpriteKit
import PlaygroundSupport
class GameScene: SKScene {
let gameArea: CGRect
override init(size: CGSize) {
let maxAspectRatio: CGFloat = 16.0/9.0
let playableWidth = size.height / maxAspectRatio
let margin = (size.width - playableWidth) / 2
gameArea = CGRect(x: margin, y: 0, width: playableWidth, height: size.height)
super.init(size: size)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
// Create the SpriteKit View
let view = SKView(frame: CGRect(x: 0, y: 0, width: 500, height: 500))
// Create the scene and add it to the view
let scene = GameScene(size: CGSize(width: 500, height: 500))
scene.scaleMode = SKSceneScaleMode.aspectFit
scene.backgroundColor = .white
view.presentScene(scene)
// Add a red box to the scene
let redBox = SKSpriteNode(color: SKColor.red, size: CGSize(width: 200, height: 200))
redBox.position = CGPoint(x: 250, y: 250)
redBox.run(SKAction.repeatForever(SKAction.rotate(byAngle: -5, duration: 5)))
scene.addChild(redBox)
// Show in assistant editor
PlaygroundPage.current.liveView = view
PlaygroundPage.current.needsIndefiniteExecution = true
