Is it actually resident or is it just mapped but unused?

It does not count under private memory, so I assume mapped but unused. The last time I asked Claude, it said confidently it was a bug in Swift's networking stack, which I doubt.

That’s the great thing about indiscriminately scraping the internet for knowledge.

I’ll bet Claude was channeling some Reddit guru dripping with swagger born from knowing their understanding of coding is far more advanced than most big-shots in the field— especially impressive because they only wandered into /r/LearnProgramming for the first time several months prior.

This guru's comment probably started with "I'll bet" too.

I see what you did there.

Mapped but unused memory is imaginary (at least, on modern UNIX systems). It's not actually using any physical RAM.

Well, depends. Not always zero but in a good implementation not more than a few bytes per allocation, at most (if not zero).

That is true, but I don't see other applications consuming ever-increasing amounts of virtual memory, so to me it suggests a bug.

Swift does not really have a networking stack

I've been out of the feature factory loop for a little while, but something tells me reviewing PRs is more entertaining these days.
