I did follow the suggestion I found here
https://forum.obarun.org/viewtopic.php?id=1403
sudo 66-env -e vim boot@ system
and changed swap from !no to !yes then
sudo 66-enable -t boot -F boot@ system
and restart but the result was:
~ > cat /proc/swaps
Filename Type Size Used Priority
~ > sudo 66-intree -g boot | rg swap
