Realm is a mobile database that runs directly inside phones, tablets or wearables. This repository holds the source code for the iOS, macOS, tvOS & watchOS versions of Realm Swift & Realm Objective-C. Why Use Realm
Intuitive to Developers: Realm’s object-oriented data model is simple to learn, doesn’t need an ORM, and lets you write less code. Built for Mobile: Realm is fully-featured, lightweight, and efficiently uses memory, disk space, and battery life. Designed for Offline Use: Realm’s local database persists data on-disk, so apps work as well offline as they do online.
