Swift abstraction for cache prefetching?

Does Swift have any intrinsics (or similar) for cache prefetching? Or is there a library somewhere on the interwebs that has already wrapped the relevant assembly (presumably prfm on AArch64?)?

I of course tried web searching, but I couldn't come up with any keyword set that wasn't confused with myriad higher-level forms of caching (like network requests and UIImages and all sorts of such stuff).
