iOS Object-Oriented Swift Inheritance What is Inheritance?

How to do this: "Create an instance of the class RoundButton and name the instance rounded"?

I'm confused here!

Please help in figuring this out.

Code is attached below.

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.self

You are very close but you need to pass the parameter for RoundButton - It should look something like this:

var rounded = RoundButton(width: 10, height: 10)

Any number should work - Hopefully that makes sense? :)
