Pseudo code for how I would like to write a server in Swift

server.swift

var server = Squid.Server()

var router = Squid.Router()

router.get('/login') {
  return Authentication.Login(originalURL: $0.originalURL)
}

router.get('/post/:int') {
  return Post.Single(postID: $1) // $1 has type of Int
}

server.use(router)

let logger = Squid.Logger()

server.use(logger)

server.start(port: 8080)
