Hi Swift community,
I've gotten quite used to needing AI-enabled code editors like Cursor and Windsurf. But I've noticed that often the LLM while debugging has to write a lot of print statements during test driven development to inspect variables. Reminds me of human debugging with console.log. I thought that this was rather inefficient and noticed that there could be a link between Model Context Protocol and Swift's LLDB.
I'm exploring the idea of building a debugging MPC server for Swift.
Key proposed features:
- Source Control Integration
- Real-time diff/patch file handling
- File change notifications
- Patch application management
- Debugging Support (via LLDB integration)
- Variable inspection and modification
- Step over/into/out debugging controls
- Dynamic breakpoint management
- Call stack visualization and navigation
Implementation approach:
- WebSocket-based protocol for real-time communication
- LLDB Python bindings for debugger control
- Platform-agnostic design to support iOS, macOS, and Linux development
Questions for the community:
- Would this kind of tool be valuable for your Swift development workflow?
- What additional features would you want to see?
- Are there existing solutions that partially solve this that we should consider integrating with?
- Would you be interested in contributing to this effort?
I've started prototyping this and would love to get the community's thoughts before investing more time in the implementation.
Best,
Max
