About the Book
Parsing JSON in Swift will teach you to harness the power of Swift and give you confidence that your app can gracefully handle any JSON that comes its way.
This edition includes two bonuses as part of The REST & JSON in Swift Bundle: The 5-Part Guide to Getting Started with Swift + The transcript from our Live Q&A about REST & JSON in Swift.
You'll learn:
- How to use NSJSONSerialization to transform JSON into Swift types, and why you should avoid using AnyObject whenever you can
- The dangers of forced type casting and how to avoid them
- Simple strategies you can use to make your JSON deserialization more concise, readable, and elegant
- Whether to return nil, empty, or throw an error when transforming JSON into an array of model objects
- How to write unit tests to increase your confidence in your parser's correctness
You'll go from fighting an uphill battle against an uncooperative compiler to having a JSON parser that's proven to be stable with automated tests.

About the Author
Josh Brown
Hi, I’m Josh Brown. I’ve been developing for iOS since 2009 and teaching it for just as long. These days, I get to help people learn iOS every day through my workshops, video courses, this book, and my blog. I love seeing what people learn and do with their new knowledge and skills, so if you use anything I’ve written or recorded to build something cool, I’d love to hear from you. Just send me an email or talk to me on Twitter.
In addition to teaching, I also enjoy building apps, which is how I got into iOS in the first place. I was tired of building software I couldn’t really show or explain to my friends and family. I love that now I can pull my iPhone out and show them what I built – or at least point them to the App Store and say “I made that.”
Most recently, I’ve been contributing to the Swift open source project, writing this book, and helping my clients refactor their code and track down crashes.
