It is also the only good way to use LLMs to manage projects/workspaces

You can use it for non-Apple platforms btw. Swift on Linux, Android, Windows, WASM. Projects like https://swiftcrossui.dev (with major contribution from Miguel de Icaza recently) and https://skip.tools for instance make this all the more productive

Neat, I may check that out.

For my Swift backends running on Linux I have just been using SPM and when working on macOS open the manifest directly. I haven't really done anything with a non-web UI with Swift outside of blessed platforms.
