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 stable…

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. The majority of…

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 information is described…

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.

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 alongside the Swift…

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 outlines alone, but…
