For me, my setup was working with a "local" package inside an Xcode project. After adding the Localizable.xcstrings file, I had to quit Xcode and reopen it then build the project using the main app target scheme selected for it to work as expected and populate the strings. This seems like a bug in Xcode 16.2.
Editing local packages from Xcode app projects is buggy in other ways as well, for example, deleting a file in a local package from the Package Dependencies section in the project navigator does not work and I have to close the app project and open the local package alone for deleting to work.
I'm starting to get used to quitting and starting Xcode in my setup.
