Hello Leonardo:

So your method looks good, but you are giving the wrong values to width and points.

width = width + points is not going to work for this challenge.

try 

width = points

Good luck

Hello Jhoan, I did not get why are we assigning width to points? Can you please show me complete code and explain why you did so ? Appreciation in advance!

Hello Kamran:

We are not assigning width to points, its the other way around. Points to width.

class Button {
  var width: Double
  var height: Double

  init(width:Double, height:Double){
    self.width = width
    self.height = height
  }
  func incrementBy(points: Double){
  height += points // Here we assign the points from the functions parameter.
  width += points
  }
}

Hope this answers your question.

I don't think I gave the wrong values what you did is just a different way of doing the same thing... But thanks, it worked anyway...
