Not necessarily of 2.5.1 (it hinges on whether or not the swipe needs to
be precise/on a specific path, or if it allows for dragging...there's a
bit of nuance on when a swipe does indeed fall under this SC).

However, it sounds like this would fail 2.1.1 unless there's some
keyboard behaviour also present (and yes, even on "mobile", users may be
navigating using a bluetooth-connected keyboard).

It depends how the sliders are implemented. If done correctly (like
native sliders), the value can be changed by screen reader gesture
(either swipe up/down, or using volume keys), and there's built-in
keyboard behaviour (using cursor keys to change the value).

If not, though, then that would also again fail 2.1.1 most likely.
