Hi MIK Agency !

You where asked to

(1) add a method named incrementBy which will accept a parameter named points:

  func incrementBy(points:Double){
  }

(You did this already)

(2) Within the method(!) add points to the width and height properties:

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

This leads to the complete class:

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 
  }
}
