How do you use Interface builder with Swift?

Question

When hooking Swift code up to a Storyboard, how do you add the IBAction and IBOutlet tags?

Answer 1

Add IBAction and IBOutlet attributes to variables and functions so they can be visible in Interface builder.

class ViewController: UIViewController {

    @IBOutlet var label: UILabel?

    @IBAction func doTap(x:UIButton) {
        println("Tapped: \(x)")
    }
}
