You are missing the parameters when you are calling the RoundButton class

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)
}

@Ryan Shenton Thank you for reply. I was already able to find the answer. I hope this will help anyone who has difficulties on that stage challenge.
