Dismissing Modal View Swift

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

I am developing an app in Swift. Currently, I am working on an info screen (legal notices, credits, documentation, etc) that will be presented modally atop the main screen.

The expected behavior is that, when a button press triggers Dismiss in InfoViewController, the modal view controller is dismissed.

Here’s 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’s the layout of the storyboards:

When I press the button, the app crashes and doesn’t dismiss the modal view controller.

It compiles, suggesting it is not a syntactual error.

Here’s the LLVM debugger output:

If you need any more info, let me know. Thanks so much.

The main issue here is Unknown class InfoViewController in Interface Builder file.

You need to make sure that (in 'Custom Class' section)

1) The class in the storyboard is set to InfoViewController

2) The module is set to 'Current - your project name'

screen shot include to show which part of Interface builder I am referring to
