The SG Reference is a quick reference guide to Apples new programming language: Swift.
This guide is not meant to be a lesson in general programming, but rather a quick reference for Swift objects, syntax, conventions, etc.... You get the gist, flip through to get familiar with Swift, use it as a handy tool when writing the next big iOS app, curl up with The SG Reference and a hot cup of Cocoa (the kind of Cocoa you drink), or read it to your children to get them to sleep.
