My code works on Swift but not on exercise

I don'k know whats wrong, my code works on Swift, but on the exercise i got the error "You didn't add the incrementBy method to the class RoundButton or click Preview for compiler errors.", Can someone help me pls?

  var width: Double
  var height: Double

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

Hi David Montalvo!

First, you have a typo :smiley: Happens to us all! I'd encourage you to check the spelling of increment in your incrementBy call. Also, we need to do the width and height increments differently. Take a look at my RoundButton class and see what I mean:

class RoundButton: Button {
  var cornerRadius: Double = 5.0
  override func incrementBy(points: Double) {
    width += 7.0
    height += 7.0
    }
}

Good luck! :thumbsup:
