Hi Ermie,

The challenge question is as follows.

We need to provide a means to increase the size of our Button. So we are going to add a method named incrementBy which will accept a parameter named points. (Within the method add points to the width and height properties).

What this means is we need to add the value of points onto our already created height and width class properties, we can do this by using the shorthand increment operator as seen below.

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

The other way we can achieve the desired result is by reassigning the value of height and width by adding the values together and setting the value again which is what the above example is achieving.

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

Happy coding!
