Swifter

Swifter is an HTTP server engine written in Swift. An application creates an HttpServer in code, registers handlers for routes, and calls start(), so the server runs as the application’s own process. The README shows examples for routes, serving files from a directory, redirects, HTML built in Swift and WebSocket handlers. It is installed through the Swift Package Manager, CocoaPods or Carthage.

Worth knowing

The default branch is stable. The master branch adds an experimental web-framework layer on top of it, and the 2.0 branch, an async IO version, is marked experimental in the README.
