Swift3 如何在我的SpriteKit游戏中实现UISlider？[Swift 3]

我搜索了关于如何向SpriteKit添加UIKit元素的更新指南，但没有找到任何有效的方法。具体来说，我想在我的游戏设置屏幕上添加一个滑块，在上面的标签中显示滑块的当前值。另外，如果滑块工作，是否意味着任何UIKit元素都可以以相同的方式成功添加

class Settings: SKScene {

//MARK: - Properties
var settingsLabel = SKLabelNode()
var backLabel = SKLabelNode()

var shipType1 = SKSpriteNode()
var shipType2 = SKSpriteNode()
var shipType3 = SKSpriteNode()
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)

//MARK: - didMove and willMove
override func didMove(to view: SKView) {
    settingsLabel = self.childNode(withName: "settingsLabel") as! SKLabelNode
    backLabel = self.childNode(withName: "backLabel") as! SKLabelNode

    shipType1 = self.childNode(withName: "shipType1") as! SKSpriteNode
