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.

Swift has long supported development using multiple IDEs including VS Code, Xcode, Neovim, and Emacs. Swift is also compatible with editors that implement the Language Server Protocol (LSP). This growing ecosystem of editor support is particularly significant as Swift continues to show its versatility across platforms and development environments, including agentic IDEs.

The Swift extension for VS Code is now officially available on the Open VSX Registry, the vendor-neutral, open source extension registry hosted by the Eclipse Foundation. The extension adds first-class language support for projects built with Swift Package Manager, enabling seamless cross-platform development on macOS, Linux, and Windows. This milestone brings Swift support, including code completion, refactoring, full debugging support, a test explorer, as well as DocC support, to a broader ecosystem of compatible editors and allows agentic IDEs like Cursor and Antigravity to automatically install Swift, with no manual download required.


Swift in Cursor, powered by the Swift extension on Open VSX.

To start using the Swift extension in any Open VSX-compatible editor, simply open the Extensions panel, search for ‘Swift’ and install the extension.

If you’re using Cursor, getting started is easier than ever. Check out our new dedicated guide: Setting up Cursor for Swift Development. It walks you through the setup, features and includes how to configure custom Swift skills for your AI workflows.

Swift now has support for a wider range of modern editors and IDEs to meet developers where they are. Download the extension, try it out in your editor of choice, and don’t forget to share your feedback!
