Just add it to your /etc/fstab.

/path/to/swapfile   none   sw  

It will get added to the swap at boot with the rest of the swap space. I
would recommend giving your swap partitions/files different priorities
in this case so that the faster partitions are higher priority and the
swap files are lower priority.  See swapon(2) for more details.

/dev/of/swap/partition   none   sw,pri=1
/path/to/swapfile        none   sw,pri=0
