Would a human being find swimming in liquid water easier or more difficult on a high gravity planet?

Buoyancy doesn't depend on the strength of gravity, beyond requiring that there *is* gravity. If you would float in water on Earth, you'd float just the same on Jupiter. (Let's say its a swimming pool inside an airship to get round the issue of Jupiter having no solid surface).

But it will require more effort to change the depth you float at in the higher gravity. Swimming underwater is faster than swimming on the surface - FINA actually restricts the distance a swimmer may be submerged for during a race because of this. Assuming you are positively buoyant then on Jupiter you would find it harder to submerge and would "pop up" faster.

It will also require more effort to lift your own arms above the water and press them below the water.

So higher gravity, slower and more tiring swimming. But you will be able to swim, you're not going to sink like a stone.
