Sounds like things have improved in the last couple years, thanks for the information. If they get to the point where a basic database-querying microservice will usually compile on all three platforms, I could imagine a lot more server-side interest in the language. Who knows?
FWIW it's already viable to use Swift in the micro-service use-case. If you're running logic inside containers it's trivial to get a Swift service up and running.
