Dont understand the issue?
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
super.init (width:Double,height:Double,cornerRadius:Double){

17,565 PointsYou haven't defined a super.init that takes those three arguments. This pattern is seen in Objective-C, but you could do something like this (aka idk if this is Swift..y):
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){
super.init(width:width, height:height)
self.cornerRadius = cornerRadius
}
// or you could just override it
init (width:Double,height:Double,cornerRadius:Double){
self.width = width
self.height = height
self.cornerRadius = cornerRadius
}
}
