[Mazen Chami]

Description

I'm currently working on a backwards compatible package to be tested in the "new arch" and "old arch" setup. When running in the "new arch", everything works as expected. When running in "old arch", i run into a linking error in both platforms show in the screenshot below:

Here is the published NPM package

Packages

I am facing the issue If I try with (Kotlin & Swift bridge).
But If I use (Kotlin & OBJC bridge) it is working in old archs.
It would be great If i can able to write swift bridge for both old and new architectures
