Hi Jason,

module-name collision is something that keeps me up at night. I intend to solve it as properly as possible.

This will involve a proper proposal for swift proper down the line, probably involving namespacing in some form.

For now, you can either cross your fingers or fork the project that has the collision and change the module name.

However, when I got this conflict today, I was thinking this will be a problem going forward. I'm sure it's been solved already by the package manager team, but I haven't figured out how to do this from the docs yet.
