Great job @dfed
Does it mean that we should store SafeDI.swift file somewhere inside project? We should call Root.init() inside AppDelegate and without storing generated code, Xcode must fail compilation as Root.init() does not exist.
I'd prefer not to store this file because of high probability of code conflict it brings.

@pouyayarandi if you're using a build plugin the generated tree is in derived data. If you're using a pre-build script and generating the file into your git repo, I would recommend ignoring the file in git
