Exporting xcode to react-native. Is it possible to?

Question

Apple Xcode

I heard that in react-native you can somehow export from the xcode project.
That is, the react algorithm is as follows:
we write code in js and react converts it to swift and java for the respective platforms.
I have code in swift and can I convert it to js using react, so that in the future I can make an android application from react?

Answer 1

No, of course, and vice versa, React-Native does not convert code to Swift and Java, it simply exports the project, inside it is just a "shell" ("browser" engine) and React-Native code.

Answer 2

No :) I wonder who you heard it from.
