If you see the documentation about swsusp here:
https://www.kernel.org/doc/Documentation/power/swsusp.txt

It clearly states you can use a swap file.

Now I am confused as to why you say a swap file won't work.

Where am I going wrong ?

Have you looked at "man 5 systemd-sleep.conf".  It describes 4 modes.

Hibernate saves enough state so the system can be restored after 
power is "lost".   This requires stopping the filesystems, so you
have to save the state outside the regular filesystems.
