Realm is a database not exactly like any other.

Its rich feature list aside, the fact is Realm wasn't created to be an embodiment of the idea of a database it was created as an API which answers the specific needs of app developers.

Realm sports a custom-made engine, which gets you started with a database in a single line of code and reads and writes objects as if you just kept them around in memory.

With the RealmSwift API you use native objects and can push the language to its limits as you please. You never worry about multi-threading.

The plain truth is that Realm on iOS makes persisting data actually... fun!

I wrote this book with two seemingly opposite goals:

• Create the most detailed and exhaustive resource about creating iOS apps built on Realm.

• Provide an approachable and understandable learning path to both Realm newcomers and experienced developers.

Luckily, Realm provides a set of very developer friendly APIs. I had to "only" go over each topic in detail and work in some practical examples that will give enough experience to tackle real-life app development problems.

The only requirements for reading this book are at least intermediate level of understanding of Swift and iOS development.

If you've worked through our classic beginner books the Swift Apprentice https://bit.ly/2ue5EH3 and the iOS Apprentice https://bit.ly/2JdWTjD or have similar development experience, you're ready to read this book.

As you work through this book, you'll progress from beginning topics to more advanced concepts.
