Help on Question " Our Roundbutton class should have its own implementation of incrementBy......"

class RoundButton: Button { var cornerRadius: Double = 5.0

override func incrementBy(_points: Double = 7.0) { super incrementBy(points: Double)

// code's not working...help pls

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

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

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

class RoundButton: Button {
  var cornerRadius: Double = 5.0

override func incrementBy(_points: Double = 7.0) {
super incrementBy(points: Double)
}



}

1) you need the dot syntax for the super ( super.incrementBy) and you do not need to declare the type for points. replace with : super.incrementBy(points)

2) Check your curly braces it appears you may have too many if you still get errors!

Good luck!
