Good to see people getting serious about Swift cross platform projects. Let's hope it doesn't share the fate of Apple's Dylan projects. Been looking into this recently so leaving it here as friendly competition: https://air.mozilla.org/ur-web-a-simple-model-for-programmin...

Competition is good. Two frameworks doesn't mean there'll be an explosion.

So took a look and turns out already happening... Aside from perfect.org there's - https://tailorframe.work - https://github.com/glock45/swifter - https://github.com/grzegorzleszek/HTTPSwiftServer - https://github.com/izqui/Taylor - https://github.com/crossroadlabs/express ...and even mor here https://github.com/search?utf8=&q=web+framework+language%3AS... > Competition is good ... except when it isn't.

I also really have great hopes for Swift as a modern, x-platform, general purpose, compiled language. Go is not general purpose; Rust is too low level. Haskell has a too steep learning curve. Ur/Web is really great, but not at all general purpose. Why am I hung up over "general purposeness"? Well when I learn a language, it takes quite a bit of my time; then I want to be able to apply it broadly. Therefor I shun Node…

I'll admit my total naivete up front: isn't Swift already a typed language? Is there something about being a web framework that necessitates some other kind of type safety?

The more advanced a type system is, the more it depends on what you do with it when designing an API. A well designed API in a language with a rich, expressive type system can make higher-level guarantees. On the opposite side of the spectrum you could just use Strings for most of the types (it’s web after all!) and it would still be type safe, although the type guarantees wouldn’t be of much use.

    // Handle GET requests to path /users/{username}
    get("users", *) { (request, username: String) in
      return "Hello \(username)"
    }

    Route.get("users/:username") { request in
      if let username = request.parameters["username"] {
        // Return something with username
      } else {
        // TODO Return 404
      }
    }
