What's wrong?

?

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) {
  self.points = (width: 20, height: 25)
}
}

Hi there,

The incrementBy() method takes a parameter called points, as you have implemented.

This value is then added to the instance's width and height properties.

The function should look something like:

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

I hope that helps.

Steve.
