Dismiss UIAlertView after 5 Seconds Swift

Question

I\'ve created a UIAlertView that contains a UIActivityIndicator. Everything works great, but I\'d also like the UIAlertView to disappear after 5 seconds.

Answer 1

A solution to dismiss an alert automatically in Swift 3 and Swift 4 (Inspired by part of these answers: [1], [2], [3]):

// the alert view
let alert = UIAlertController(title: "", message: "alert disappears after 5 seconds", preferredStyle: .alert)
self.present(alert, animated: true, completion: nil)

// change to desired number of seconds (in this case 5 seconds)
let when = DispatchTime.now() + 5
DispatchQueue.main.asyncAfter(deadline: when){
  // your code with delay
  alert.dismiss(animated: true, completion: nil)
}

Result:
