I'm finding a few open source projects, mostly older, that lack an .xcodeproj directory hierarchy. It seems like all other crucial files are there.
Curiously enough, I'm wondering how these projects are even accessed via Xcode? I'd like to compile them, break them, fix them etc. Is there a way to open these more legacy projects?
Here's the contents of an open source Freecell project:
