iOS Object-Oriented Swift Inheritance Inheritance and Initializers

Really don't know what's wrong with this designated initializer/how to make it work? Can someone guide me?

The prompt asks you to correct the code

Button.swift
class Button {
  var width: Double
  var height: Double

  init(width:Double, height:Double){
    self.width = width
    self.height = height
  }

  func scaleBy(points: Double){
    width += points
    height += points
  }
}

class RoundButton: Button {
  var cornerRadius: Double = 5.0

  init(width:Double,height:Double,cornerRadius:Double){
    self.cornerRadius = cornerRadius
  }  
}

You're not calling the parent initializer of RoundButton.
