Disable Swift modal view

EDIT: Thanks to the person behind the answer below who installed the unknown class. However, can anyone tell me if it is correct to reject the code? I'm on vacation and can't program until I get back.

I am developing an application in Swift. I am currently working on an information screen (legal notices, loans, documentation, etc.) that will be presented on the main screen.

The expected behavior is that when you click the Reject Triggers button in InfoViewController, the Modal Viewer is rejected.

Here is the code I'm trying to use:

//This is InfoViewController, the swift file used to conorol the info screen.

import UIKit

class InfoViewController: UIViewController {

    @IBAction func Dismiss(sender: AnyObject) {
        self.dismissViewControllerAnimated(true, completion: {});//This is intended to dismiss the Info sceen.
        println("pressed")
    }
    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

}

      

        
        
        
      

    

Here is the storyboard layout:

When I click the button, the app crashes and doesn't dismiss the modal view controller.

It compiles, assuming it is not a syntax error.
