The document discusses building a micro web server in Swift. It outlines reasons for using Swift on the server side, including sharing code and frameworks between client and server. Existing Swift web frameworks like Kitura, Vapor and Zewo are presented. The value of understanding how to build a server from scratch is that it provides insight into how popular frameworks work, and networking expertise is not required. Steps for building a demo server are overviewed, with the conclusion that Swift is still developing low-level networking APIs for server development.
