Realm is a mobile database that runs directly inside phones, tablets or wearables. This repository holds the source code for the iOS & OSX versions of Realm, for both Swift & Objective-C.
- Mobile-first: Realm is the first database built from the ground up to run directly inside phones, tablets and wearables.
- Simple: Data is directly exposed as objects and queryable by code, removing the need for ORM's riddled with performance & maintenance issues. Plus, we've worked hard to keep our API down to just 4 common classes (Object, Array, Results and Realms) and 1 utility class (Migrations): most of our users pick it up intuitively, getting simple apps up & running in minutes.
- Modern: Realm supports relationships, generics, vectorization and even Swift.
- Fast: Realm is faster than even raw SQLite on common operations, while maintaining an extremely rich feature set.
Please see the detailed instructions in our docs to add Realm to your Xcode project.
Documentation for Realm can be found at realm.io/docs/cocoa.
The API reference is located at realm.io/docs/cocoa/api.

In case you don't want to use the precompiled version, you can build Realm yourself from source.
Prerequisites:
- Building Realm requires Xcode 6.
- Building Realm documentation requires appledoc
Once you have all the necessary prerequisites, building Realm.framework just takes a single command: sh build.sh build. You'll need an internet connection the first time you build Realm to download the core binary.
Run sh build.sh help to see all the actions you can perform (build ios/osx, generate docs, test, etc.).
Executing the examples under the examples/ folder, requires that you have built the Realm.framework.
See CONTRIBUTING.md for more details!
