  Yes! Someone finally said it. The worst are the operators. You don't need these libraries and their lack of tests.

  Noticed this might be an ad about a book... Parsing JSON in Swift. The bubble is real. What developer would buy this? What's next, a book about NSURLSession?

  And here's your regularly scheduled announcement that the actual JSON parsing is done by the library call NSJSONSerialization.JSONObjectWithData(...) in line 3 of the code.

  The rest is just getting the parsed data out of already parsed nested dictionaries and arrays in a way that makes the type checker happy. Calling that "parsing" is probably the biggest myth of them all (though agreed about all the other myths).

  Swiftz (https://github.com/typelift/Swiftz) offers well tested implementation of operator definitions and constructs from functional language. It takes inspiration from Scalaz and Haskell. If I were to write a library using wacky operators, I'd at least use well defined and maintained definitions.

  Why is parsing JSON a problem in 2016 ?

  doesn't look like it's protecting against nsnull values
