Swift Development Now Supported Across a Broader Ecosystem of IDEs

Expanding Horizons: Swift in Modern Editors

Swift has long been a favorite for developers on Apple platforms, but its reach is growing far beyond Xcode. Today, Swift programmers can choose from a diverse range of integrated development environments (IDEs), including popular editors like Cursor, VSCodium, AWS Kiro, and Google’s Antigravity. This expansion is made possible by leveraging compatibility with the VS Code extension ecosystem and the official Swift extension now listed on the Open VSX Registry.

For years, Swift has supported development in multiple IDEs such as VS Code, Xcode, Neovim, and Emacs. It also works with any editor that implements the Language Server Protocol (LSP). The latest milestone, however, brings first-class Swift support to a new generation of agentic IDEs—tools that use AI to assist coding—making Swift more versatile and accessible than ever.

The Open VSX Registry and Official Swift Extension

The Swift extension for VS Code is now officially available on the Open VSX Registry, a vendor-neutral, open-source extension marketplace hosted by the Eclipse Foundation. This registry serves as an alternative to Microsoft’s own marketplace, giving editors like VSCodium and other Open VSX-compatible tools direct access to extensions. The official Swift extension includes full language support for projects built with Swift Package Manager, enabling seamless cross-platform development on macOS, Linux, and Windows.

With this extension, developers gain features such as code completion, refactoring, full debugging support, a test explorer, and DocC support. More importantly, agentic IDEs like Cursor and Antigravity can automatically detect and install Swift without any manual downloading—a huge time-saver for teams using AI-assisted workflows.

Supported IDEs and Agentic Environments

The updated Swift support covers a broad spectrum of editors:

Cursor – An AI-first editor that integrates deeply with the Swift extension for intelligent code suggestions and debugging.
VSCodium – A free, open-source build of VS Code that relies entirely on the Open VSX Registry.
AWS Kiro – Amazon’s cloud-oriented IDE, now capable of handling Swift projects via the same extension.
Google Antigravity – A newer agentic IDE that supports automatic Swift setup.

This ecosystem is particularly significant for developers who work across multiple platforms and need consistent tooling. Whether you are building server-side Swift on Linux, crafting iOS apps on macOS, or experimenting with Swift on Windows, you can now use a familiar editor environment.

Getting Started with Swift in Your Preferred IDE

To start using the Swift extension in any Open VSX-compatible editor, follow these simple steps:

Open the Extensions panel in your editor.
Search for “Swift”.
Install the official extension by the Swift project.
Open or create a Swift Package Manager project, and enjoy full language support.

If you are using editors like VSCodium, the extension will be fetched directly from the Open VSX Registry. For Cursor or Antigravity users, the setup is even more automated—just open a Swift file, and the editor will prompt you to install the required tools.

A Guide for Cursor Users

Cursor has become a favorite among developers who want AI-powered coding assistants. To help Swift developers get started, the Swift team has published a dedicated guide: Setting up Cursor for Swift Development. This guide walks you through the setup process, explains key features, and shows you how to configure custom Swift skills for your AI workflows. Whether you are using Cursor for scripting, app development, or server-side work, the guide covers everything you need.

We encourage you to download the extension, try it out in your editor of choice, and share your feedback. The Swift community thrives on collaboration, and your input helps shape future improvements.

Conclusion

Swift’s growing IDE support means developers are no longer tied to a single environment. With the official extension now on the Open VSX Registry, you can work with Swift in Cursor, VSCodium, AWS Kiro, Google Antigravity, and many other editors. This opens up new possibilities for cross-platform development and AI-assisted workflows. Get started today, and experience Swift wherever you code.
