Going a bit off topic but...
If you don't feel comfortable with partitioning your disk to manually add a swap partition, perhaps you can consider using swap files.
Unless you install multiple distributions on your machine and want them all to use the same swap partition to save disk space or you use hibernation and thus absolutely need a swap partition larger than the amount of RAM your computer has, a better alternative is to use swap files.
Files are more flexible since you can easily make them larger or smaller, add/remove additional swap files, you can also play with the priority for example to give a higher priority on a faster storage (Priorities work for both files & partitions btw). I don't know how it is today but some years ago it wasn't easy to have encrypted swap partitions. If you use swap files and your partitions are encrypted, you don't have to worry about it.
It's always good to have a swap to prevent a crash if your system should run out of memory.
Personally I always have a swap file. If the machine has lot of RAM, I make a smaller file and I set the swappiness to 1. If the machine has less RAM, I make a larger file and I set the swappiness to 10.
And when I have punctual tasks that I know will require lot of RAM, I add an additional swap file that I remove when I am done.
