Swift extension lands on Open VSX Registry

Swift extension now in Open VSX Registry enables automatic installation across Cursor, VSCodium, and other LSP-compatible editors without manual setup.

Summary

Removes friction for cross-IDE Swift development; agentic IDEs can auto-install the extension, and you get code completion, debugging, and test explorer in any Open VSX-compatible editor. Workflow expands beyond Xcode without extra toolchain management.

Why it matters

Implementation verdict

Replaces manual extension installation and editor-specific configuration. Requires only an Open VSX-compatible editor (Cursor, VSCodium, AWS Kiro, Google Antigravity all supported). Worth adopting now if you're already in one of these editors; no blocking concerns.
