Four Months in the Making: SwiftMCP 1.0 is Here

After four months of intensive development, I’m thrilled to announce that SwiftMCP 1.0 is feature-complete and ready for you to use.

For those just joining, SwiftMCP is a native Swift implementation of the Model Context Protocol (MCP). The goal is to provide a dead-simple way for any developer to make their app, or parts of it, available as a powerful server for AI agents and Large Language Models. You can read the official specification at modelcontextprotocol.io.

I did a SwiftMCP 1.0 Feature Speed Run on YouTube, if that’s what you prefer.

Introducing SwiftMCP

I’m thrilled to announce SwiftMCP, a Swift macro-based framework that elegantly exposes your Swift functions as powerful Model Context Protocol (MCP) tools for AI assistants. After months of careful refinement, SwiftMCP now delivers the experience I’ve always dreamed of: turning standard Swift documentation directly into AI-integrable tools—effortlessly.

Who is Cocoanetics?

The word Cocoanetics comes from the words Cocoa (the framework we use to program iOS apps) and Genetics (to build, make up). It simply states that we have living and breathing iOS development a level even deeper than “in your blood”.

Our apps and parts are often experiments, mostly pieces of art, but always carefully handcrafted. We’re still learning and getting better at coding every day. You benefit from this because our code gets better all the time and we share what we learn on our blog.
