You don't need a swap partition. It's simple to create a swap file
('man mkswap'). In fact before I upgraded my RAM to 32GB I got by with
just zram (which is compressed and much faster than a hard drive), but
YMMV of course. If zram is enough, the only time you actually need swap
on secondary storage is if you want to hibernate (not suspend) your
system.
