Help Please

I am struggling to add points to the method, I am not sure if it is asking me to return something?

Cheers

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 width; height (5)
    }

  }
}

Hey Alex, First try declaring a var property named "points" within the new func incrementBy. Then, assign a default Double value of whatever you want. I did 10.0. Just below that, assign the new points property to width and height...and BOOM!.

class Button {
  var width: Double
  var height: Double

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

  func incrementBy(points: Double) {
  var points = 10.0
  width += points
  height += points
  }
}
