Xcode way to print "Hello World" when button is clicked in OS X Swift application?

Question

I'm an experienced Java and Visual Studio developer, but I am just starting out with Swift & Xcode. I am an utter noob, who has never written a line of objective-c. I want to print "Hello World" when I click on the button that I have added in the "Storyboard" view for my application. But I cannot figure out how to get Xcode to insert an event method anywhere in the swift source code files. I’ve read %60 of "The Swift Programming Language", but I don't know any of the cocoa apis yet. Most examples reference objective-c files that do not exist in a Swift application. I also am not using the iOS platform, so I suspect some examples I've pasted (i.e. @IBAction func buttonTapped ) fail because they are not applicable to OS X applications.

I would appreciate a little help :)

You just need to add a label and a button to your window. Then you need to connect your label outlet to your code.

You need to connect your button to your viewController also:

import Cocoa

class ViewController: NSViewController {

    @IBOutlet var strLabel: NSTextField!

    override func viewDidLoad() {
        super.viewDidLoad()

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

    override var representedObject: AnyObject? {
        didSet {
        // Update the view, if already loaded.
        }
    }

    @IBAction func printHello(sender: AnyObject) {
        strLabel.stringValue = "Hello World !!!"
    }

}
