What is a CGFloat?
Swift version: 5.6
A CGFloat is a specialized form of Float that holds either 32-bits of data or 64-bits of data depending on the platform. The CG tells you it's part of Core Graphics, and it's found throughout UIKit, Core Graphics, Sprite Kit and many other iOS libraries.
If you have a Float or Double and need a CGFloat, you can convert it like this:
let myCGFloat = CGFloat(myDouble)
