We need to provide a means to increase the size of our Button. So we are going to add a method named incrementBy which will accept a parameter named points. (Within the method add points to the width and height properties). Im stock. Please help me
class Button {
var width: Double
var height: Double
init(width: Double, height: Double){
self.width = width
self.height = height
}
func incrementBy(points: Double) {
points = width, height
}
}

"...within the method add points to the width and height properties..." asks you to add points to the width and height properties like this:
width = points + width
height = points + height
class Button {
var width: Double
var height: Double
init(width:Double, height:Double){
self.width = width
self.height = height
}
func incrementBy(points:Double){
width = points + width
height = points + height
}
}
