    var width: Double
    var height: Double

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

Hi Max,

Try:

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

That adds points to both width and height.

Hope that helps!

Steve.
