Dummy SPM targets with no headers fail with error - fail("No header files were provided.")

After updating to version 0.34 of rules_swift_package_manager some SPM libs stopped to work with following error
fail("No header files were provided.")
For example it appears when trying to add aws_sdk.
It seems in all cases it happens because those sdks create dummy targets in their Package.swift file. Those targets contain only single empty.m file and binary dependencies. Rules_swift_package_manager can't find any headers while creating module map for those targets and fail with error.

Are there any options to bypass this behaviour?

Sorry for the delay. I will need to investigate to better understand what is happening.

Was this working in a previous version of rules_swift_package_manager? @mikhailmulyar
