Swift Language Quick Reference

Swift is the programming language that Apple introduced two weeks ago at WWDC14.  I’ve spent the last week pouring over the language guide, condensing (almost) all of the facts into a double-sided 8.5×11″ quick reference sheet.  I invite feedback, and hope that it’s useful to others.  I recommend at least going through the Swift tour before diving in.

    Are you planning to update the cheat sheet for all the new Swift syntax?

    Yep, I am. But, I now realize now that every-other week there will be syntax changes. I’m considering waiting a bit until things seem to settle down some.

    Great work!

    On the closures section, Xcode is claiming an ‘&’ is required as sort changes the name requirement. That is: “sort(names, { $0 < $1 })" goes to "sort(&names, { $0 < $1 })". Similarly for the other three sort examples.

    Have a great day!

    You’re absolutely correct. I’m planing on revising the entire cheat-sheet now that Swift version 1 is GM, I just haven’t gotten to it yet.
