My code won't compile online it worked in Xcode and said there were no problems but the online version gives me an error

I put this in online and I get the Bummer! error when it works just fine on Xcode is there anything I am doing wrong code wise?

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: Double = 5.0
  }
  var rounded = RoundButton(width: 10.0, height: 10.0)
}

It's almost correct, but as I see you put the subclass inside the class Button

class Button {
  var width: Double
  var height: Double

  init(width:Double, height:Double){
    self.width = width
    self.height = height
  }
}
class RoundButton: Button{
        var cornerRadius: Double = 5.0}

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