PerfectlySoft/Perfect ? reverse-engineered prompt

Build me a server side Swift toolkit that lets people make lightweight web apps and REST APIs on macOS and Linux.

I want the core pieces in place so a Swift developer can start a server, handle requests and responses, route URLs, render simple templates, and plug in things like WebSockets or database connectors later if needed. Keep it clean and practical, with tests included, and make sure it works with Swift 5 on both macOS and Ubuntu.

If you need to check current Swift docs or best practices online while putting it together, go ahead. I mainly want a solid foundation that feels like a real framework someone could build an app on, not just a demo.
