-For iOS, while you can manually link the old way using [react-native own tutorial](https://reactnative.dev/docs/linking-libraries-ios), we find it easier to use cocoapods.
-If you wish to use cocoapods and haven't set it up yet, please instead refer to [that article](https://engineering.brigad.co/demystifying-react-native-modules-linking-ae6c017a6b4a).

-The method is nearly identical to the [manual linking method for iOS](https://reactnative.dev/docs/linking-libraries-ios#manual-linking) except that you will include the `node_modules/react-native-webview/macos/RNCWebView.xcodeproj` project in your main project and link the `RNCWebView-macOS.a` library.
