how to delay a execution?

Question

I am creating a small project such that after pressing a button which will take me to the next view controller using the navigation controller - can i delay the function to execute the navigation controller after some time

i am using this code-

import UIKit

class ViewController: UIViewController
{
   @IBAction func enterButtonPressed(_ sender: UIButton)
   {
       let vc = storyboard?.instantiateViewController(withIdentifier: "ViewController2") as! ViewController2
       self.navigationController?.pushViewController(vc, animated: true)
   }

   override func viewDidLoad()
   {
      super.viewDidLoad()
   }

   override func didReceiveMemoryWarning() 
   {
      super.didReceiveMemoryWarning()
   }

}

Answer 1

Suppose sender.tag holds the duration which is 0 for proceed , 5 or 10

var playTimer:Timer?

//

@IBAction func btnClicked(_ sender:UIButton) {

    playTimer?.invalidate()

    playTimer = Timer.scheduledTimer(withTimeInterval: TimeInterval(sender.tag), repeats: false, block: { (T) in

        // play the audio

    })
}
