What expected expression is missing?

I've searched the internet for swift expected expression errors and I haven't come up with much. The code looks correct to me but maybe I'm making a fatal mistake I'm not sure. What expected expression is missing?

Button.swift 
class Button {
  var width: Double
  var height: Double
   init(width:Double, height:Double){
    self.width = width
    self.height = height
  }

  class RoundButton: Button {

  var cornerRadius = 5.0

  }
var rounded = RoundButton.self (width: 0.0, height: 0.0)

Check your curly braces... You are missing one after self.height = height. Also, no need to use self on the RoundButton class.

class Button {
  var width: Double
  var height: Double

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

class RoundButton: Button {

  var cornerRadius = 5.0

}

var rounded = RoundButton(width: 20.0, height: 10.0)
