Realm's Swift SDK enables your iOS, macOS, tvOS, and watchOS applications to interact with Realm using either the Swift or Objective-C programming languages. This page details how to install Realm in your project and get started.

Before getting started, ensure your development environment meets the following prerequisites:

  • Xcode version 13.1 or higher.
  • When using Xcode 13, a target of iOS 9.0 or higher, macOS 10.9 or higher, tvOS 9.0 or higher, or watchOS 2.0 or higher.
  • If using Swift Package Manager with Xcode 13, target of iOS 11+ or macOS 10.10+ is required.
  • When using Xcode 14, a target of iOS 11.0 or higher, macOS 10.13 or higher, tvOS 11.0 or higher, or watchOS 4.0 or higher.
Note

There are special considerations when using Realm Database with tvOS. See Build for tvOS for more information.

You can use SwiftPM, CocoaPods, or Carthage to add the Realm Swift SDK to your project.

Add the following line at the top of your source files to use Realm:

Realm Database should only add around 5 to 8 MB to your app's download size. The releases we distribute are significantly larger because they include support for the iOS, watchOS and tvOS simulators, some debug symbols, and bitcode, all of which are stripped by the App Store automatically when apps are downloaded.

If you have build issues after using one of these methods to install Realm, see our troubleshooting guidelines for information about resolving those issues in realm.
