Think i may have a bug bc i am putting my code correctly in the function method and its not working.

I put the points parameter in my coding method with no errors but it says that i didn't put it in the method can someone please help???

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) -> Double{
  return (points+width)+(points+height)
  }
}

I think you are reading it wrong. You are returning a Double and it didn't say to return anything. Also, it says to just add the points variable to width and to height, it didn't say to add them together. The way I understood it, I wrote it like this and it worked:

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