Comment by trojanfoe on Xcode C++ how to read file inside xcframework and pass it to sqlite load_extension?

I think you may have issues getting your app onto the App Store. I recently had a project that used a .dylib in an app extension and it was rejected during submission with an obscure ITMS-90427 error. This was solved by embedding the .dylib in a .framework, but I doubt that would work for you.
