Show HN: Want to learn how to code? We made an app for that (weheartswift.com)

No really - the book intentionally leaves out some concepts in order to make things easy for people who are learning.

Although, the book has only a bit o theory - the minimum you will what to know to be able to use the language - going trough it my be a good introduction to Swift - arrays are different from Obj-c, you have tuples and closures are first class objects.

I think the answer depends on your background :)
