Below is my code for this challenge. However I'm no way to pass it :( P/S: I seem to be having problem on the coding console to0. Sometime it's no responding when click or typing on the console. It's a bug or just to me? Thanks
class Button { var width: Double var height: Double
init(width:Double, height:Double){ self.width = width self.height = height }
override func incrementBy(points: Double){ width += points height += points } }
class RoundButton: Button { var cornerRadius: Double = 5.0
override func incrementBy(_ points: Double = 7.0) { super.incrementBy(points)
} }
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
}

14,452 PointsHi @wilsonkwan, you don't need the term super as override writes over the super version with a default value, hence why we set points to 7.0. Apart from that the function is the same so the contents is the same, effectively the only thing you needed was to set its default value. Here is the code:
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){
width += points
height += points
}
}
Hope this helps
Dom
