Developing Realm

Building Realm

There are three ways to build Realm

1. [Recommended] Using Xcode, open Package.swift. With this approach you can build either against a released Core version or a custom branch.
2. Using Xcode, open Realm.xcodeproj. This will download the version of Core specified in dependencies.list/REALM_CORE_VERSION and build the Swift SDK against it.
3. From the command line, run ./build.sh build. Similarly to 2., this also downloads Core and builds against it.

Building against a custom branch of Core

To build Realm against a custom Core branch, update Package.swift by updating the Realm Core dependency from exact to branch:

    dependencies: [
-        .package(url: "https://github.com/realm/realm-core.git", exact: coreVersion)
+        .package(url: "https://github.com/realm/realm-core.git", branch: "*your-custom-branch*")
    ],
