In order for Xcode builds to work with custom environment variables you need to use xcodeproj.bazel_env. This just takes the extra step of filtering out all other environment variables, ensuring more analysis cache hits. You can already do this in your own tools/bazel, but now people can get the benefit regardless.
This change is needed for shared outputs bases to be performant.
