13,515 PointsYou need to give the class RoundButton a member named points, otherwise the override function incrementBy, whose parameter is points, will have no meaning to the class RoundButton.
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
var points = 7.0
override func incrementBy(points: Double) {
}
}
