iOS Object-Oriented Swift Classes and Objects Classes and Their Methods

Classes and Objects

I have tried this multiple ways and cannot get the code to go through. what am I missing?

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 {
  return width + (points:); height + (points:)
  }
}

Nate, it looks like you are writing this method to return the values of the incremented height and width, all you need to do is increment them like the following:

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
         width += points
    }
}
