Node in swift not appearing

问题

I'm trying to put a node in my game on Swift, but it's not appearing. Please help!

import SpriteKit
import GameplayKit

class GameScene: SKScene {


    override func didMove(to view: SKView) {

        let levelLabelNode = SKLabelNode(fontNamed: "Arial")
        levelLabelNode.text = "Level"
        levelLabelNode.fontSize = 30
        levelLabelNode.fontColor = SKColor.white
        levelLabelNode.position = CGPoint(x: self.frame.size.width/2, y: self.frame.size.height*0.75)
        self.addChild(levelLabelNode)

here's the code

I copied the same code I also faced the same problem coz the font color is white its match with background color.if you have changed the font's color then you can able to see the label in the screen

let levelLabelNode = SKLabelNode(fontNamed: "Arial")
        levelLabelNode.text = "Level"
        levelLabelNode.fontSize = 30
        levelLabelNode.fontColor = SKColor.green
        levelLabelNode.position = CGPoint(x: self.frame.size.width/2, y: self.frame.size.height*0.75)
        self.addChild(levelLabelNode)
