@christianselig in case it helps, I have a fastlane action set up to bump the version and build code (it's essentially a shell script)

I managed to resolve one of the warnings by manually editing the pbxproj and removing all the outdated CURRENT_PROJECT_VERSION's for the extensions. But that didn't fix it for the other extension, ...
@finnvoorhees @christianselig I’ve been doing this with all of my apps and it's helped simplify version management.
I also do the same with the build number because I still like having control of it, though it does mean I have to remember to increment it before I archive a new build.
