I have one project where I have XYZ scheme and target. I have Localizable.string under XYZ target for localization. I want to create a ABC target (duplicate of XYZ) and set custom language support for it. Let's say I have english, french and german for XYZ, I want hindi, japanese and chinese for ABC. I did the below steps I went to Manage scheme and duplicated the XYZ (duplicate scheme = ABC). I added new localization file only for ABC (LocalizationForABC.string) and made sure those reflect in File Inspector -> Target (only ABC selected) and also checked in Build Phases -> Copy Bundle Resources (LocalizationABC exists). When I run the ABC target under let's say french, it works fine but when I build the project ABC, and remove french from XYZ, ABC is broken and it only runs in english. Am I missing something here ?

I have a custom localisation function in my project that enforces the inclusion of the bundle parameter (specifically so that Swift packages are forced to include the Bundle.module value). While migrating to String Catalogs, I noticed that my custom localisation function wasn't being recognised by the automatic extraction that the Swift compiler is doing, but only in my Swift package targets. Is there a way to set something like LOCALIZED_STRING_MACRO_NAMES in Swift Packages?
