Is it as mature or have as large of a (server-focused) community? No, but I might consider this over Go or Rust because I already know Swift (from iOS development), and I haven't used Go or Rust at all. Fluency and confidence speed development time.

In all honesty though, even though I really like Swift, I'd probably choose something else I already know well like ASP.NET Core until the Swift-on-the-server scene matures.

As for cross-platform capabilities, IBM has contributed a lot of effort to running Swift on Linux and in the cloud. They even have a web-based REPL you can check out.

Swift and Rust are remarkably similar if you're familiar with what Swift calls "protocol oriented development" (I think it's called). Really, it's just a version of Haskell's typeclasses in disguise.
