如何在Swift游乐场中设置带有纹理的SKNode的SKScene？

import SpriteKit

class CustomScene: SKScene {
    let customNode = SKNode()
    
    override func didMove(to view: SKView) {
        addChild(customNode)
    }
}

let texture = SKTexture(imageNamed: "texture.png")
let spriteNode = SKSpriteNode(texture: texture)
customNode.addChild(spriteNode)

spriteNode.position = CGPoint(x: 0, y: 0) // 设置节点位置
spriteNode.size = CGSize(width: 100, height: 100) // 设置节点大小
spriteNode.zPosition = 1 // 设置节点在场景中的层级
// 其他属性设置...

let view = SKView(frame: CGRect(x: 0, y: 0, width: 400, height: 300)) // 创建SKView视图
let scene = CustomScene(size: view.frame.size) // 创建自定义场景
view.presentScene(scene) // 展示场景
