NullPointerException when generating Xcode project

See original GitHub issue

I’m currently trying to generate an Xcode project for a build target and am hitting this error:

I’m unsure exactly what’s causing this to happen - I will update if I have more exact steps to repro.

Sure, PRs are always welcome.

Generally send out a draft of the PR first so we can comment on general approach and high level design. No need to flesh it out we know which direction we should go in.

For project generation specifically look at the --combined-project and --build-with-buck flags, those are the future in some sense.
