A subclass should be outside the base class. Not in it.

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
}

var rounded = RoundButton(width: 1.0, height: 1.0)
