Not quite sure I follow the importance of multiple inits with regard to creating an instance of Rectangle?

If we create multiple init methods then we can initialize the struct in different ways depending on the information we have at hand. If we already have the origin and size, we can use the first method init(origin: Point, size: Size). If we only have the x and y coordinates of the origin, and the width and height of the rectangle, but we don't have the Point and Size instances for these, then we would use the second init method init(x: Int, y: Int, width: Int, height: Int) . If we have the center and the size, instead of the origin and the size, then we use the third init method init(center: Point, size: Size) .

I assume that this will be useful so that in our app we have flexibility to choose the init method that suits our input data, without having to write more code later to work out for example where the origin of the rectangle will be if we know where the center is.

Hi Kevin

As a real-world example: Several CAD applications offer the possibility to draw a rectangle in multiple ways, depending on what information you have and how you want to draw your rectangle.
