Confused

Hey guys! I don't really understand how to solve this problem. Do I need an initializer value and how do i return both the height and width? please help!! thanks!

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 
  }
}

Hi Nihar,

You just need to add the points to the stored width & height, so:

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