Warning in Project of XCFramework: Module 'ModuleName' was not compiled with library evolution support

Question

I'm trying to create XCFramework, which has inside several dependencies imported with SPM. I set BUILD_LIBRARIES_FOR_DISRTIBUTION to YES for target.

But this warning inside of XCFramework Project next each line import <ModuleName> makes me curious: is there something wrong there?

Warning:

Module 'ModuleName' was not compiled with library evolution support; using it means binary compatibility for 'XCFrameworkName' can't be guaranteed

Note: Archiving and creating xcframework succeeded.

FWIW, to explain the warning message, XCFramework is linking to ModuleName but ModuleName isn't exporting the .interface linker file that is needed to guarantee ABI compat (because it doesn't have BUILD_LIBRARIES_FOR_DISTRIBUTION set). The risks of doing that are unclear to me though, I am looking for that information still. My question is, is there a risk that the library will link and potentially crash at runtime due to ABI incompat? – Rozek

Did you solved that? – Duodecillion

hi @tdtkien, my temporary solution was using source code of framework-project instead of frameworks. – Cancer

I couldn't solve that but new binary has been accepted by Apple yesterday. So I think this is not really a serious bug – Duodecillion
