In this case Swift is being used on the server, so that could be an officially supported platform[0] which if I recall correctly is macOS, Ubuntu, CentOS, Amazon Linux 2, and Windows as of Swift 5.3.

Swift on Linux is pretty much WIP, with an ecosystem that is Mac first and hardly considers another platforms.

On Windows with luck 5.3 will be the first version that the compiler actually works, let alone existing libraries that barely work on Linux.
