I am planning to implement swap file over swap partition on Ubuntu 16.04. Going through various blogs I found that hibernation is only supported by swap partition and resizing is privileged on swap file. Are there any significant reasons for not using swap file in Linux systems?

    there's no difference between swap file and swap partition nowadays. But you should avoid them and use zram instead https://unix.stackexchange.com/q/499485/44425 – phuclv Sep 05 '19 at 16:21

The original kernel (4.13) of 17.10 and later solved the slow swap file issue. Performance was the sole reason to change. Before then, a swap partition was superior.

Which kernel do you use? Find it with cat /proc/version then click [edit] and add that useful information. If < 4.13, stay with a swap partition.

If your motivation is enabling hibernation, see this article on alternative methods.
