This doesn't appear to be fixed, I've been struggling testing out various configurations, running the export through CLI, isolating packages but to no avail. We have a complex application with external dependencies but also local packages. I am only able to export localizations if my sort of testPackage which I've been using to try and isolate the problems, has NO local packages, external packages do not cause any issues (currently have Factory and Firebase included). I have done some of the following without success: set Architectures = arm64 set Excluded Architectures = x86_64 i386 set Build Active Architecture Only = true CoreUtility, a local package, is included in every package and has minimal dependencies, so i included that as a single import for InternationalizationService , i have gone through and commented out every single dependency in that Package file but it still tries to build for MacOS I tried including #ifelse logic specific to MacOS within CoreUtility but still no success
