I got an error message during navigating from first view controller to second view controller. My coding is like this one

let vc = LoginViewController(nibNam

I Give you my code to make a transition. In this example the action is connecting to an UIButton. So don't forget to set it. Don't forget to set the name of your ViewController in the transition method.

Don't forget to set your storyboard too. Your need to have one view per viewController. Connect each ViewController to each view in storyBoard. You can see on the screenshoot bellow

class PresentationViewController: UIViewController {
    override func viewDidLoad() {
         super.viewDidLoad()

         var playButton   = UIButton.buttonWithType(UIButtonType.System) as UIButton

         let image = UIImage(named: "YourPlayButton") as UIImage?

         playButton.frame = CGRectMake(0, 0, 100, 100)
         playButton.center = CGPointMake(self.view.frame.width/2, self.view.frame.height/2)
         playButton.addTarget(self, action: "transition:", forControlEvents:  UIControlEvents.TouchUpInside)
         playButton.setBackgroundImage(image, forState: UIControlState.Normal)

         self.view.addSubview(playButton)
    }


func transition(sender:UIButton!)
{
    println("transition")
    let secondViewController = self.storyboard?.instantiateViewControllerWithIdentifier("YourSecondViewController") as UIViewController

    let window = UIApplication.sharedApplication().windows[0] as UIWindow
    UIView.transitionFromView(
        window.rootViewController!.view,
        toView: secondViewController.view,
        duration: 0.65,
        options: .TransitionCrossDissolve,
        completion: {
            finished in window.rootViewController = secondViewController
    })
}
}
