The fact that Mac apps almost never crash/quit no matter how much stuff you load, and the ability to switch between apps almost instantaneously with each app always presenting just as you last left it is all due to its ability to swap. You're not supposed to notice it, so your comment just means it's doing its job.
That's supposed to be what Apple has brought to the M1/M2 iPads with the new OS (as long as they have at least 128 mb storage). But I don't have one of those iPads, so I don't have any first-hand experience as to how well it works. But the implementation is still limited compared to what can be done on a Mac. It's a little ambiguous, but iOS has a 16 GB limit on VM (I'm not sure if that's per app, or total), whereas on Mac, the swapfile is permitted to continue to grow as long as there is more disk space available.
I'm curious about that as well.
