How to I delay or slow down transition between view controllers?

So I have a button on screen that is connected through storyboards with a push Segway. I press the button and it goes to the next view controller.

If I wanted to slow the transition up by say 1-2 seconds how would I go about doing that?

You can create a method in your first view controller that uses the performSegueWithIdentifier method after a delay.

You then connect the button on the view controller to that method.

Code example:

Storyboard

Here I have the initial view controller with a manual segue to the second view controller.

enter image description here

I've connected the Fire Method button to an IBAction on the initial view controller, with this code:

import UIKit

class ViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

// This method is connected to the Fire Method button
@IBAction func fireMethodBttnTouched(sender: AnyObject) {

    let delay = 1 * Double(NSEC_PER_SEC)
    let time = dispatch_time(DISPATCH_TIME_NOW, Int64(delay))
    dispatch_after(time, dispatch_get_main_queue()) { () -> Void in

        self.performSegueWithIdentifier("showSecondViewController", sender: self)
    }
}

}

You can adjust the delay constant as needed.
