This pull request fixes an issue when we use increment_build_number_in_xcodeproj or increment_version_number_in_xcodeproj passing in the target and build_configuration_name options. Before the fix, action changed values in both configurations at once

oof. sorry I missed this ! I was wondering if you'd mind adding a couple unit tests to cover this behaviour please? 🙇 I see these still pass all the tests, and what you've said about this does make sense. merging and releasing. thank you for your contribution!
