When creating a swapfile on vanilla, you have to keep in mind:

• to put the file in /var, not the root (/) (Otherwise, you might run into space issues when doing an upgrade in the future)
• to chattr +C if you are using btrfs for /var, which is the default

Example:

host-shell pkexec
truncate -s 0 /var/swapfile
chattr +C /var/swapfile

Here, change the 3G to the size that you want:

fallocate -l 3G /var/swapfile

chmod 0600 /var/swapfile
mkswap /var/swapfile
nano /etc/fstab

add this line to the end of the file:
/var/swapfile none swap defaults 0 0
then save the file with Ctrl+X then Y then Enter

swapon -a
exit

You can test if it worked by running:
host-shell pkexec swapon --show
