Expanding Swift's IDE Support

You can now write Swift in a broader range of popular IDEs, including Cursor, VSCodium, AWS’s Kiro, and Google’s Antigravity. By leveraging VS Code extension compatibility, these editors tap directly into the Open VSX Registry, where the official Swift extension is now live.

This is huge, long time coming. Interested to see if there is SwiftUI support.
This extension is for "pure" Swift development, not iOS development. I doubt the latter will ever officially happen. It's possible to make it work for iOS at an unofficial capacity though by hooking into the extension's LSP support. We did this at Spotify to enable iOS development in Cursor for Bazel iOS projects: https://github.com/spotify/sourcekit-bazel-bsp
What's the point then? Because nobody use Swift outside of iOS app development.

> Because nobody use Swift outside of iOS app development

Because that isn't true, people do use it outside of iOS app dev, and is becoming more true as time goes on to boot.

It's also a chicken-and-egg problem: no one will use Swift for non-iOS tasks if the tooling support isn't there. The more investment into it, the more it will be picked up for other tasks.

But it's been used outside of Apple-specific things since the early days in various niches.
