Do people like printed reference cards? I’m working on a Swift Cookbook. It started as web pages but I’ve moved it to Github. Considering doing an ePub or trying to cram a lot into a one pager. Having Strings, Sets, Arrays, Dictionaries, and Functional examples on one page might be useful, for example. Here are my functional examples: https://github.com/melling/SwiftCookBook/blob/master/functional.md https://github.com/melling/SwiftCookBook/blob/master/functio... If you know a couple languages, my thinking is that a few pages of examples should be enough to get started in another language.
