Swift on server may not have "great performance", but compared to mainstream stuff it definitely has "pretty good performance" while still providing a somewhat nice language. I guess the key selling point is, well, being able to use Swift on the server (some people do like the language). It is pretty useful for sure. Certainly not the only choice. That Swift is compatible with almost nothing on Linux sounds strange, not sure what you mean by that. E.g. I find it particularly nice for writing Apache modules (the Swift C integration is really neat). P.S.: While Apple puts minimal effort in anything but macOS and iOS, others put significant effort into Swift on Linux. Like IBM.
