I don't understand what I am supposed to do.

What does it mean when it says to add 'points' to the width and height properties?

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) {
  }
}

You've done well at defining the the function incrementBy, and syntax is correct. Now as to what to put in the function body

What does it mean when it says to add 'points' to the width and height properties?

It means add the points to the self.width, and also adds it to the self.height.

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