Create an NSButton using a CGRect to define its frame:

var button = NSButton(frame: CGRect(x: 100, y: 100, width: 80, height: 30))

Call setbuttonType: using a value from the NSButtonType enumeration. The default style is MomentaryPushInButton:

button.setButtonType(NSButtonType.MomentaryLightButton)

Set the title property to change the text displayed on the button:

button.title = "Click Me!"

The NSButton class uses the target/action pattern to indicate when the button has been clicked. Set the target to the object that is going to handle the click event. Then use a Selector to set the action property:

button.target = self

button.action = Selector("buttonClicked:")

Next, add the button to the window’s contentView property:

self.window.contentView.addSubview(button)

Finally, implement the action method to handle the button click:

func buttonClicked( sender : NSButton ) {

println("Button clicked")

}
