iOS Object-Oriented Swift Inheritance Overriding Methods

Posted by Michael McKinley

I'll be extremely upset if this code isn't right!

"Our RoundButton class should have its own implementation of the incrementBy method. Override the incrementBy method in the RoundButton class and default the points parameter to 7.0"

Can someone please explain to me what I need to do? The compiler isn't recognizing that I am overriding the implementation

Button.swift 
class Button {
  var width: Double
  var height: Double

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

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

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