Thanks! I think these frameworks, especially Vapor and Kitura are ready to be used in simple production apps. They’re both still very young and getting lots of improvements at rapid peace. Companies like Node, how’s backing the development of Vapor, are using the framework for all their new client projects in production as of late 2016. Others are using either framework for micro-services or simple websites. We’ll surely see more and more companies moving to server-side Swift as both the language and the frameworks evolve.
