class Button { var width: Double var height: Double
init(width:Double, height:Double){ self.width = width self.height = height } }
class RoundButton: Button { var cornerRadius: Double = 5.0 }
let rounded = RoundButton() //this line particularly
class Button {
var width: Double
var height: Double
init(width:Double, height:Double){
self.width = width
self.height = height
}
}
class RoundButton: Button {
var cornerRadius: Double = 5.0
}
let rounded = RoundButton()

instead of
let rounded = RoundButton()
try
var rounded = RoundButton(width: 2.0,height: 2.0)
Variable or constant doesn't matter in this case... and 2.0 is just an example... important is that you give the Super Class some values so it knows what to do. I hope this helps
