You've put your RoundButton class inside your Button class. It should look like this:

class Button { var width: Double var height: Double

init(width:Double, height:Double){
    self.width = width
    self.height = height
}

}

class RoundButton: Button { var cornerRadius = 5.0 }

Hope this helps!
