Detecting key press event in Swift

Question

I\'m trying to find a way to detect if a key (on a keyboard) has been pressed on Swift. Any ideas and suggestions will be greatly appreciated.

You have to override the keyDown-method.

var direction:String = ""

override func keyDown(theEvent: NSEvent!) // A key is pressed
{
    if theEvent.keyCode == 123
    {
        direction = "left" //get the pressed key
    }
    else if theEvent.keyCode == 124
    {
        direction = "right" //get the pressed key
    }
    println("Key with number: \(theEvent.keyCode) was pressed")
}
