Hey guys! I don't really understand how to solve this problem. Do I need an initializer value and how do i return both the height and width? please help!! thanks!
class Button {
var width: Double
var height: Double
init(width:Double, height:Double){
self.width = width
self.height = height
}
func incrementBy (points: Double) -> Double {
return
}
}

You just need to add the points to the stored width & height, so:
func incrementBy(points:Double) {
self.width += points
self.height += points
}

1,524 PointsHey Damien, its still saying that I'm incorrect. It wants me to declare something first. Any ideas?

27,419 PointsI have pasted the function into the class provided and it accepts the answer. You need to add this function to the existing, so it will look like:
class Button {
var width: Double
var height: Double
init(width:Double, height:Double){
self.width = width
self.height = height
}
func incrementBy(points:Double) {
self.width += points
self.height += points
}
}

27,419 PointsLooks like you double posted this question Duplicate, not sure if you can, but maybe worth trying to delete this one? Or worse case, create a dummy answer and mark it as correct.
