Help me here! I don't know if I understand what to do.

Someone that can explain the requirements.

Button.swift
class Button {
    var width: Double
    var height: Double
    var points: Double

    init(width:Double, height:Double, points:Double){
        self.width = width
        self.height = height
        self.points = points
    }
    func incrementBy (points: Double){
        self.width = self.width + points
        self.height = self.height + points

    }

}

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 = self.width + points
        self.height = self.height + points
    }
}
let button = Button(width: 50, height: 50);
button.incrementBy(50)

This should work. Notice that I removed all of the points variables except for as a parameter. There is no need to scope the variable that large. Its only being used within that one method.
