I can't figure out how to create and instance of a class. I don't understand what the question is asking me.

The challenge says that I need to "Create an instance of the class RoundButton and name the instance rounded." I know how to make instances but at the same time, I'm not fully sure what I am suppose to be doing. I have tried many different things and none of them seem to be working so I just keep trying to start from the beginning. I'm not getting close because the challenge keeps saying "Your code could not be compelled." I don't even know what I am doing wrong. Please help

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 

}

Hello Austin:

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 

}

let rounded = RoundButton(width: 1.2,height: 2.4)  // instance
