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()
   }

}

You want to play audio after 5/10 sec or play with offset of 5/10 sec ? To schedule after 5/10sec use NSTimer. — NeverHopeless, Jun 27 '18 at 11:47

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

    })
}

Try this one

var timeLimit = 5.0
DispatchQueue.main.asyncAfter(deadline: .now() + timeLimit, execute: {
    //Play your audio here
    //Audio will play after 5 seconds here
})

Actually asyncAfter is not guaranteed to be called at a specific time, it is guaranteed to be run after specified time, not sure this is correct answer – mihatel Jun 27 '18 at 12:32
