The Swift for Visual Studio Code extension, which brings language support for Apple’s Swift programming language to Microsoft’s Visual Studio Code editor, now is available on the Open VSX Registy, an Eclipse Foundation-hosted open source registry for VS Code extensions.

The Swift for Visual Studio Code extension adds first-class language support for projects built with Swift Package Manager, enabling seamless cross-platform development on macOS, Linux, and Windows, according to Apple. The extension brings Swift language support including code completion, refactoring, full debugging support, a test explorer, as well as DocC support to both VS Code and a broad ecosystem of compatible editors and allows agentic IDEs like Cursor and Antigravity to automatically install Swift. No manual download is required.

Capabilities of the Swift for VS Code extension include:

• Jump to definition, peek definition, find all references, and symbol search
• Error annotations and fix suggestions
• Automatic generation of launch configurations for debugging with LLDB DAP
• Automatic task creation
• A Project Panel to quickly run actions and view dependencies
• Test Explorer view

Most features of the Swift for VS Code extension, however, only work with projects that build with Swift Package Manager. These projects will have a Package.swift file in their root folder. Support for Xcode projects (.xcodeproj) is limited. The Swift extension for VS Code also is available on the Visual Studio Marketplace.
