Swift 6.4 is now available. Swift aims to be a great choice across the stack, from apps and servers to systems code, embedded devices, and the browser. This release deepens that support, and makes everyday code easier to write. Highlights include: Swift Build is now the default in Swift Package Manager, so your projects build the same way on Linux, macOS, and Windows. Subprocess reaches 1.0, a sta…
When your Swift program hits a breakpoint and stops so you can inspect it, the debugger’s expression evaluator has to find the exact Swift module your code was built from. Until now, that lookup wasn’t always precise. The upcoming Swift 6.4 release will include changes, begun in Swift 6.3, that address this by updating how the Swift compiler references explicitly-built Swift modules in debug info.…
Welcome to “What’s new in Swift,” a curated digest of releases, videos, and discussions in the Swift project and community. Here’s an update from guest contributor Simon Leeb on Swift’s progress as a language for web scenarios: Hi, Simon here! I am the creator of the elementary-swift project, a collection of packages born from a simple wish: I want to build web UIs in Swift and ultimately help Swi…
Embedded Swift is a subset of Swift that’s designed for low resource usage, making it capable of running on constrained environments like microcontrollers. Using a special compilation mode, Embedded Swift produces significantly smaller binaries than regular Swift. While a subset of the full language, the vast majority of the Swift language works exactly the same in Embedded Swift. Additional infor…
Welcome to “What’s new in Swift,” a curated digest of releases, videos, and discussions in the Swift project and community. Swift is built by contributors working on far more than the language and compiler. Alexander Sandberg reflects on what that kind of contribution looks like, and why there’s a place for you too: Hi, I’m Alex. Four years ago I joined the Swift Website Workgroup to help care for…

We are organizers of CommunityKit, a community-organized conference that takes…
Since its launch, Swift Package Index has become an essential part of the Swift ecosystem, helping developers discover quality packages, evaluate compatibility, and make informed decisions about dependencies. Started by Dave Verwer and Sven A. Schmidt, the project currently indexes thousands of packages and serves as a central hub for package documentation. Recently, Swift Package Index has grown…
TrueType is a widely used vector font standard for rendering text in web pages, PDFs, operating systems, and applications. Familiar fonts like Helvetica, Garamond, and Monaco are all built on TrueType outlines. The format specifies a hinting interpreter intended to help outlines rasterize faithfully on low-resolution displays. Modern high-resolution displays enable beautiful typography from outlin…
The Swift Ecosystem Steering Group is excited to announce the creation of the Networking workgroup! Workgroups are community-led efforts, formally recognized by the project, to advance key areas of Swift.

Welcome to “What’s new in Swift,” a curated digest of releases, videos, and discussions in the Swift project and community. To start, we’re focusing on some of the many local meetup groups sharing Swift content: Around the world, local meetup groups and conferences bring Swift developers together, and some even predate Swift itself! Many have YouTube channels where they share videos from their eve…
Goodnotes has been helping millions of users take handwritten notes on iPad for over a decade, earning recognition as Apple’s iPad App of the Year in 2022. Today, the same Swift code that powers our iOS app also runs seamlessly in web browsers through WebAssembly, delivering the exact same ink rendering and note-taking experience users love. This journey demonstrates that Swift excels as a cross-p…

We’ve invited one of the authors to be this month’s guest contributor: Hi, I’m Adam Fowler, an open source developer working in the Swift on server ecosystem. I am excited to announce the 1.0 release o…
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 compatib…
Welcome to “What’s new in Swift,” a curated digest of releases, videos, and discussions in the Swift project and community. Swift 6.3 has been released, expanding Swift into new domains and improving developer ergonomics. A highlight of its release is work to improve cross-platform build tooling. Owen Voorhees shares an update on that effort: Hi! I’m Owen, a lead engineer on the Core Build team at…
Swift is designed to be the language you reach for at every layer of the software stack. Whether you’re building embedded firmware, internet-scale services, or full-featured mobile apps, Swift delivers strong safety guarantees, performance control when you need it, and expressive language features and APIs. Swift 6.3 makes these benefits more accessible across the stack. This release expands Swift…

The new Windows workgroup joins a growing list of Swift workgroups, including the Android workgroup, Build and Packaging workgroup, and Testing workgroup wh…
There are many interesting, useful, and fun C libraries in the software ecosystem. While one could go and rewrite these libraries in Swift, usually there is no need, because Swift provides direct interoperability with C. With a little setup, you can directly use existing C libraries from your Swift code. When you use a C library directly from Swift, it will look and feel similar to using it from C…
Welcome to the latest digest of news from the Swift project. Each edition, we share updates that we hope will be useful to you whether you’re writing code with Swift or contributing to the language as a whole, and we start with an introduction from this edition’s guest contributor: As we near the end of the year, it’s a time for reflection and gratitude. We’re profoundly grateful for the energy, c…
Since the announcement of the preview Swift SDK for Android, the Android workgroup has seen a lot of interest in how it works and what’s next. Please read on for some answers to common questions about the technology and its future, and try out the new Swift 6.3 SDK nightly previews. How Swift works on Android Swift compiles directly to native machine code on Android, the same way it does on most o…
Every application has configuration: in environment variables, configuration files, values from remote services, command-line flags, or repositories for stored secrets like API keys. But until now, Swift developers have had to wire up each source individually, with scattered parsing logic and application code that is tightly coupled to specific configuration providers. Swift Configuration brings a…
