I think that needs some improvements.  The swap file should really be owned by root, and located in the root directory "/".

To create the file with zero size in / :
$ sudo touch /swapfile
Then :
$ sudo dd if=/dev/zero of=/swapfile bs=1M count=512
512+0 records in
512+0 records out
536870912 bytes (537 MB) copied, 64.1348 s, 8.4 MB/s
$ sudo mkswap /swapfile
Setting up swapspace version 1, size = 524284 KiB
no label, UUID=312d835c-759d-4d5c-8c60-2ac4e6bf7117
$ sudo swapon /swapfile
$

After rebooting you will have to make the file the swapfile again :
$ sudo swapon /swapfile
$

To check it is the swapfile :
$ sudo swapon --summary
Filename                Type        Size    Used    Priority
/swapfile                     file        524284    0    -1
$
