By example, how Objective-C was simplified into Swift

Objective-C to Swift conversion cheat sheet – Hacking with Swift

If you’re moving from Objective-C to Swift, or perhaps from Swift to Objective-C, it can be useful to have a quick start guide showing equivalent code samples in both languages. Well, that’s exactly what you’ll find below: a Rosetta stone of Apple development, demonstrating variables, collections, functions, classes, and more.

Well done Paul.

A very nice collection of comparisons between the two languages I work with every day and how the Swift team at Apple condensed and clarified intent in the new language.

I love Swift but it still has some rough edges, currently: type erasure is a mug’s game: Generic Protocols vs Non-Generic Protocols, WTF?
