@rwenderlich Hi, I really love this article, and I just have a little question about the detail.

Why I often see the the use of rect.height in CGPoint.x and rect.width in CGPoint.y. like this:

  let mountainStart = CGPoint(x: rect.size.height / 2, y: 100)
  let mountainEnd = CGPoint(x: rect.size.height / 2, y: rect.size.width)

I find it quite hard to image and understand, does my understanding about rect height and width has any deviation?
