Xcode 14.3 failed to verify module interface of 'project'

There were a lot of issues when trying to run the app after upgrading Xcode to the latest, 14.3 version.

The one I am facing now is:
failed to verify module interface of 'projectName' due to the errors above; the textual interface may be broken by project issues or a compiler bug
along with No such module Firebase

Edit: Seems like it is not up to Firebase nor any other pod since people are having the same issue for different pods.
I have tried these things but no success:

  • updating all pods to the latest version
  • updating Cocoapods to the latest version 1.12.0
  • cleaning build folder and derived data, as always
  • updating CommandLineTools to the newest version(14E222 > 14E222b)
  • downgrading CommandLineTools to the previous Xcode 14.3’s version 14C18

    Add -no-verify-emitted-module-interface to Other Swift Flags to your Build Settings if you are using SPM.

    In my case, I added @_implementationOnly when importing the library and it stopped happening.
