Welcome to CGOperators, a small Swift framework that enables you to easily manipulate Core Graphics’ vector types (CGPoint, CGSize and CGVector) using math operators. It can help you write compact, yet highly readable code when dealing with things like image sizes and frame-based layouts.

Examples

Add two vectors

let point = view.frame.origin + CGPoint(x: 10, y: 20)
let size = image.size + view.frame.size
let vector = physicsWorld.gravity + player.size

Subtract two vectors

let point = view.frame.origin - CGPoint(x: 10, y: 20)
let size = image.size - view.frame.size
let vector = physicsWorld.gravity - player.size

Multiply a vector with a constant

view.frame.size = image.size * 4
button.frame.origin = superview.bounds.size * 2
physicsWorld.gravity = player.position * 10

Divide a vector by a constant

view.frame.size = image.size / 4
button.frame.origin = superview.bounds.size / 2
physicsWorld.gravity = player.position / 10
