Try running Carthage update for an iOS app with 80 frameworks. Ever seen a Mac hit 55GB of ram? MacOS kills it. It takes many of these runs, and all this does is fetch prebuilt binaries. Yes, everything I said here is beyond stupid.
Is it necessary to update _all_ of them at once? I think that's the same problem as OP... rebuilding the whole world is slow, so why not do it incrementally?
Also, 80 frameworks ⊙⊙ I'm assuming some of these are internal, and written in Swift, meaning they can't be compiled into static libs (easily).
