1,236 PointsHow do I add the "points" parameter to the "height" to the incrementBy Method? This is a class - init - func challenge.
class Button { var width: Double var height: Double
init(width:Double, height:Double){
self.width = width
self.height = height
}
func incrementBy(points: Double) {
}
// how do I add points to the width and height properties?
class Button {
var width: Double
var height: Double
init(width:Double, height:Double){
self.width = width
self.height = height
}
func incrementBy(points: Double) -> width {
}
}

17,565 Pointsclass Button {
var width: Double

init(width:Double, height:Double){

}
func incrementBy(points: Double) {
height += points
}
}
If I'm understanding this correctly, you simply want to define a method that increments your points property by the number of points passed to incrementBy. Since the return type for this is void (nothing), we don't need to strongly type it. We then use the += operator to add the points to the buttons height. You may need to prefix height with self.
