How to open another view controller when OK is pressed in alert.addAction in iOS 9

I want to display a viewcontroller called InViewController, when the "OK" from the add.alertAction is pressed. 

if ((user) != nil) {               
   let alert = UIAlertController(title: "Success", message:   "Logged In", preferredStyle: .Alert)
   alert.addAction(UIAlertAction(title: "OK", style: .Default) { _ in })
   self.presentViewController(alert, animated: true){}
}

Here's how you can do that , I'm just updating the good work of Victor Sigler

you follow his answer with this little update .. 

 private func alertUser( alertTitle title: String, alertMessage  message: String )
{
   let alert = UIAlertController(title: title, message: message,   preferredStyle: .alert)
    let actionTaken = UIAlertAction(title: "Success", style: .default) { (hand) in
        let storyBoard = UIStoryboard(name: "Main", bundle: nil)
        let destinationVC = storyBoard.instantiateViewController(withIdentifier: "IntroPage") as? StarterViewController
        self.present(destinationVC!, animated: true, completion: nil)

    }
    alert.addAction(actionTaken)
    self.present(alert, animated: true) {}
}

You can add a completionHandler to the UIAlertAction when you add it to do it what you want, like in the following way:

if ((user) != nil) {               
    let alert = UIAlertController(title: "Success", message:   "Logged In", preferredStyle: .Alert)

    let OKAction = UIAlertAction(title: "OK", style: .Default, handler: { _ -> Void in 
        let storyBoard = UIStoryboard(name: "Main", bundle: nil)
        let nextViewController = storyBoard.instantiateViewControllerWithIdentifier("ViewControllerA") as! ViewControllerA
        self.presentViewController(nextViewController, animated: true, completion: nil)
    })

    alert.addAction(OKAction)
    self.presentViewController(alert, animated: true){}
}

To set the StoryboardID you can use Interface Builder in the Identity Inspector, see the following picture:

enter image description here

I put everything in the above code referencing ViewControllerA, you have to set the name of your UIViewController according what you want.

EDIT:

You are pointing to a UIView or some other object on the StoryBoard. Press the yellow indicator on top of the other objects which is your UIViewController, like in the following picture:

enter image description here

I hope this help you.

let alert = UIAlertController(title: "Success", message: "Logged In", preferredStyle: .Alert)
let action = UIAlertAction(title: "OK", style: .Default) { (action) -> Void in
  let viewControllerYouWantToPresent = self.storyboard?.instantiateViewControllerWithIdentifier("SomeViewControllerIdentifier")
  self.presentViewController(viewControllerYouWantToPresent!, animated: true, completion: nil)
}
alert.addAction(action)
self.presentViewController(alert, animated: true, completion: nil)
