NativeModules is always empty. Visual Studio Code + Windows for iOS?

It seems there might be a misunderstanding in your question. The statement "NativeModules is always empty" is related to React Native development, not iOS development on Windows using Visual Studio Code.

NativeModules is a part of the React Native framework, and it provides a way to communicate between JavaScript and native code (Java for Android and Objective-C/Swift for iOS). If you are working on a React Native project, it is expected that NativeModules would be empty when running your JavaScript code outside the React Native environment.

However, when it comes to iOS development on Windows using Visual Studio Code, there is an important point to clarify: Officially, Xcode (the development environment for iOS) is only available on macOS. This means you cannot use Xcode directly on Windows to build, test, and run iOS applications.

If you need to develop iOS applications, the most common approach is to use a macOS machine or a cloud-based macOS service (such as MacStadium) to build and test your iOS apps. You can use Windows for coding and use macOS for actual iOS development and testing.

Alternatively, you can consider using cross-platform frameworks like Flutter (which supports iOS and Android) or Xamarin (which allows iOS development through Visual Studio on Windows), where you can develop for multiple platforms, including iOS, using Windows as your primary development environment. However, please note that building and testing iOS applications still require access to a macOS machine or cloud-based macOS service.

In summary, to develop iOS applications, you need access to macOS and Xcode, which are not natively available on Windows. If you are working on a React Native project, NativeModules being empty is expected when running your JavaScript code outside the React Native environment.
