MongoDB Realm iOS SDK¶
The MongoDB Realm iOS SDK enables client applications on the iOS, macOS, tvOS, and watchOS platforms to access data stored in local realms and interact with MongoDB Realm services like Functions, MongoDB Data Access, and authentication. The iOS SDK supports both Swift and Objective-C applications.
The iOS SDK does not support Swift or Objective-C applications written for environments other than iOS, macOS, tvOS, and watchOS.
To learn how to add the MongoDB Realm iOS SDK library as a dependency to your iOS application, see Install Realm for iOS.
The Realm Data Model¶
You can store a wide variety of data within realms stored on your device. With Realm Sync, you can share updates to that data across client devices and MongoDB Atlas.
To learn about the results returned from realm queries, see Collections.
To gracefully update the schema to a new version at runtime, see Migrations.
To learn how to query for data in local realms, see Query Engine.
For information about how to react to changes in realm data, see Notifications.
For advice on how to safely interact with Realm Database across threads in an application, see Threading.
For additional security, you can also encrypt a realm.
The iOS SDK also connects your Realm client application with your Realm app's backend services, including Functions, Services, Webhooks, Realm Sync, and built-in third-party authentication.
To get connected to your MongoDB Realm app, see Initialize the Realm App Client.
You can also access custom user data.
To learn how to connect to a MongoDB Realm app to call Functions, query data in an instance of MongoDB Atlas, and synchronize data in realms, see Call a Function.
To learn how to query for data in MongoDB remotely, see Remotely Access MongoDB.
MongoDB Realm uses additional support files, detailed in Auxiliary Files.
