The Swift in the server is still in its infancy, and most features and performances are missing.
Nonetheless, we have understood that the possibilities are endless: can you imagine, for example, having the same code to serialize and deserialize the model between the client and the server? Or having web socket communication between apps with a server implemented in Swift? That would be really cool.
There are already a couple of projects that, with a different strategy, have the same goal: to be the best and most useful server framework for Swift. One is called Zewo, https://github.com/Zewo, which is basically a collection of small and effective modules to cover all the server needs from the HTTP to routers, web sockets, and so on, and the other is called Perfect, https://www.perfect.org, which has a more conventional and monolithic approach.
Both of them are still under heavy development, and the API compatibility is not a guarantee between the versions; nonetheless, they are already...
