I'm getting no error message but it says I'm wrong.

In my method, if I don't refer to width and height as self.width and self.height, I get an error message saying that since width and height are constants, I can't change them. I set them as variables, so that doesn't make sense. When I use self in my method, I get no error message but the compiler still says I'm wrong.

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) {
      self.width = self.width + points
      self.height = self.height + points

    }
  }
}

Hi, I think you're missing the closing curley bracket on the init method? 

class Button {
    var width: Double
    var height: Double

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

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