Hi Jon, first of all you need to make subclass outside of Button class. In your code above it's inside. After that you just write var cornerRadius = 5.0 inside RoundButton curly brackets. This is what you need to write to pass the task:

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
}
