The latest updates to the Swift extension for VS Code were highlighted in the "What’s new in Swift" session at WWDC 2025. Here are the key improvements:
-
Background Indexing: Enabled by default for SwiftPM projects in VS Code and other IDEs, allowing editor features like "Jump to Definition" to stay up to date as you make changes to your project.
-
Improved Code Completion: Thanks to enhancements in SourceKit, code completion results in VS Code are now more relevant.
-
Simplified LSP Debugging: LLDB support is now included automatically when you install the Swift extension.
-
New Project Panel: This feature makes it easier to find your packages, dependencies, targets, and tasks.
-
Live Documentation Preview: You can view your project's documentation side by side with your code, and it updates live as you type.
The Swift extension is developed in open source and is available on GitHub in the SwiftLang organization. For more details, you can refer to the session What’s new in Swift (00:03:41).

We’ll show examples of Swift adoption throughout more layers of the software stack. Finally, we’ll explore new language features for both improving approachability of concurrency, and achieving peak performance when you need it.
What’s new in Swift
Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
