如何在我的SpriteKit游戏中实现UISlider？ [斯威夫特3]

Question

我已经搜索了有关如何将UIKit元素添加到SpriteKit的更新指南，但我还没有发现任何有用的内容。具体来说，我想在我的游戏设置屏幕上添加一个滑块，在其上方的标签中显示滑块的当前值。此外，如果滑块有效，这是否意味着可以以相同的方式成功添加任何UIKit元素？

class Settings: SKScene {

//MARK: - Properties

var shipType4 = SKSpriteNode()
var shipType5 = SKSpriteNode()
var shipArr: [SKSpriteNode] = []

var starCount = SKLabelNode()
var starCountLogo = SKSpriteNode()
var resetStars = SKLabelNode()
var resetHighScores = SKLabelNode()

//let slider: UISlider = UISlider(frame: CGRect(x: 0, y: -450, width: 200, height: 50)
