Question 1:
@IBOutlet var countDownLabel: UILabel!
var count = 10
override func viewDidLoad() {
super.viewDidLoad()
var timer = Timer.scheduledTimer(timeInterval: 0.4, target: self, selector: #selector(UIMenuController.update), userInfo: nil, repeats: true)
}
func update() {
if(count > 0) {
countDownLabel.text = String(count--)
}
}
Question 2:
You can do both. SpriteKit is the SDK you use for scene, motion, etc. Simple View Application is the project template. They should not conflict
