(This is my code if it helps from the VeiwController.swift)

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var timerLabel: UILabel!

var seconds = 0

var timer = Timer()

var timerIsOn = false

/

@IBAction func startButton(_ sender: AnyObject) {

timer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: (Selector(("updateTImer"))), userInfo: nil, repeats: true)

}

@IBAction func stopButton(_ sender: AnyObject) {

timer.invalidate()

timerLabel.text = "0"

}

func updateTimer(){

seconds += 1

timerLabel.text = "\(seconds)"

}

override func viewDidLoad() {

super.viewDidLoad()

/

}

override func didReceiveMemoryWarning() {

super.didReceiveMemoryWarning()

/

}

}
