9,366 PointsClasses and their methods
Hello, i'm stuck on this challenge. Can someone help me ?
This is what i have to do: 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).
My error is that my code could not be compiled. But when i preview my code it sais nothing
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) {
}
}

Courses Plus Student 23,034 PointsHey Mathis, in order to increment the button's width and height by the value passed in the points parameter you would add these two lines:
func incrementBy(points: Double) {
width += points
height += points
}
Hope this helps!
