Hi haydensteed !

Your solution is correct - there's just one curly bracket to much (just before "...var rounded = ..."):

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: 1.0 , height: 1.0)
