iOS Object-Oriented Swift Inheritance Overriding Methods

Overriding methods

I can't understand what's wrong with my code. I've tried all the variations I could find here for this task yet none is working for me...

Such as; class RoundButton: Button { var cornerRadius: Double = 5.0

override func incrementBy(_ points: Double = 7.0){ width += points height += points

} } or

class RoundButton: Button { var cornerRadius: Double = 5.0

override func incrementBy(_ points: Double){ width 7.0 points height 7.0 points } } And a few more- but you get the point. So HOW are you supposed to get this task right?

Hi :-)

The correct answer is:

class RoundButton: Button {
  var cornerRadius: Double = 5.0

  override func incrementBy(_ points: Double = 7.0){
    width += points
    height += points
  }
}

Seems to me you got it right in the first example - I don't really see the difference, but maybe you missed something tiny.

Hey and thank you for the response! It turned out (after I reached out to Treehouse team) it was probably about my bad internet connection since the answer was right but it didn't let me pass the task! Boy was I frustrated hahaha. All well now, and thank you again!
