8,391 PointsStuck on adding designated initializer
The challenge question states to fix the code to be able to run. I added the super.init(width:Double, height:Double) at the end of the RoundButton class in order to initialize the super.
Any help would be greatly appreciated! Thank you!
class Button {
var width: Double
var height: Double
init(width:Double, height:Double){
self.width = width
self.height = height
}
func scaleBy(points: Double){
width += points
height += points
}
}
class RoundButton: Button {
var cornerRadius: Double = 5.0
init(width : Double, height : Double, cornerRadius : Double){
self.cornerRadius = cornerRadius
super.init(width:Double, height:Double)
}
}
}

like this:
class RoundButton: Button {
var cornerRadius: Double = 5.0
init(width : Double, height : Double, cornerRadius : Double){
self.cornerRadius = cornerRadius
super.init(width: width, height: height)
}
}
