What is it that i am supposed to do?

Button.swift 
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

You are very close. The only thing you did wrong was to create the instance the RoundButton class within the RoundButton class. You need to move it out. 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
  }
var rounded = RoundButton(width: 4.0 ,height: 2.0)
