Ah, might have been a bit trigger happy here: this only works for SPM targets, not traditional Xcode targets, correct? That said, together with what Quinn referenced above, this should do the trick. I’ll give it a try when I’m back from my vacation.

Awesome, thanks!

Thanks for the reply! Please see FB9144883, I’ll be able to provide more details as needed. The most important aspects (apart from documenting a superset of public ∪ open symbols) would be use of pictures for diagrams of general architecture, lock-acquisition-order etc. in internal documentation — also for Objective-C(++) (see: FB9144975).
