I suppose most who do Swift at the moment also use it on front-end, since this advertises being "type-safe" what is their preferred method to connect to this JSON server from the Swift front-end in type safe manner? Also, the Fluent is clearly not type-safe, it's stringly typed ORM to database. Since many backends are just fancy wrappers to database, this part should be most important for type-safety. It's nowhere as type safe as Quill, Slick or JOOQ.
