 When using a preset, first check if it includes the `macros` plugin. If so, then you don't need to install and set up `@lingui/babel-plugin-lingui-macro`. For example, `react-scripts` already includes the `macros` plugin.

+If you're using [React Compiler](https://react.dev/learn/react-compiler), make sure that `@lingui/babel-plugin-lingui-macro` comes **before** the React Compiler plugin in the Babel plugins list. This ensures macros are expanded correctly before the compiler processes the code.

 SWC Plugin support is still experimental. Semver backwards compatibility between different `@swc/core` versions is not guaranteed. See the [SWC compatibility](/ref/swc-plugin#swc-compatibility) for more information.
 :::
 
+:::caution
+If you're using [React Compiler](https://react.dev/learn/react-compiler) with SWC, the `@lingui/swc-plugin` must run **before** the React Compiler plugin. This is necessary because Lingui macros need to be expanded before the React Compiler processes your code.
+
+However, in Next.js, the React Compiler is enabled via a simple boolean flag (`reactCompiler: true`) in `next.config.js`, and there's currently no way to control plugin ordering. As a result, Lingui may not work correctly with the React Compiler in SWC-based setups like Next.js.
