[REQ] Swift Vapor server generator

[wing328]

Is your feature request related to a problem? Please describe.

We would like to create a Swift Vapor server generator similar to what we've done for NodeJS Express and other server generators.

Do we need to have server side Swift generator as well? For now, I mostly see only client ones
