In this challenge, unlike others before there seem to be a few leaps that I am missing. I have looked for clues in other questions and I get this far. But it seems that the Button.incrementBy is looking for type Button and it fails both on Xcode and in the exercise. (Sometimes, due to the updates I assume, this is not so. the playground fails but the exercise does not)
Any help will be appreciated.
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 = width + points
self.height = height + points
}
}
var newButton = Button(width: 3, height: 10)
Button.incrementBy(7)

4,407 PointsHi Alex,
The incrementBy function is not a "class/type method", instead it is an "instance method". Because of this, you want to call incrementBy on the instance that you created.
For example:
newButton.incrementBy(7)
Hope this helps.
