my code is coming up with an error you didnt add the incrementBy .
not sure why
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 {
override func incrementBy (- points: Double = 7.0) {
width += points
height += points
}
var cornerRadius: Double = 5.0
}

you have a - sign in the methods attributes of the override function of the subclass RoundButton like Ole said, you have to change it to an _ sign for the code to work. You have to do this if you want to set a default value, like in this case.
After the change the code should look like this and it should work now:
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 {
override func incrementBy (_ points: Double = 7.0) {
width += points
height += points
}
var cornerRadius: Double = 5.0
}

Courses Plus Student 3,892 PointsYou have a minus sign before the points in your method attributes. Remove the - sign.
