Swift has matured significantly over the past decade — extending from cloud services to Windows applications, browser apps, and microcontrollers. Swift powers apps and services of all kinds, and thanks to its great interoperability, you can share code across platforms.
Swift continues to grow in popularity as a cross-platform language supporting a wide variety of use cases, with support on a variety of embedded devices, form factors that encompass wearables to server, and a wide variety of operating systems. As Swift expands, there’s value in investing in matching cross-platform…
Swift is well-suited for creating user interfaces thanks to the clean syntax, static typing, and special features making code easier to write. Result builders, combined with Swift’s closure expression syntax, can significantly enhance code readability.
In June, Apple introduced Swift System, a new library for Apple platforms that provides idiomatic interfaces to system calls and low-level currency types. Today, I’m excited to announce that we’re open-sourcing System and adding Linux support! Our vision is for System to eventually act as the single home for low-level…
We’re delighted to announce the general availability of Swift 6. This is a major new release that expands Swift to more platforms and domains.
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.

This will allow Swift developers, regardless of the platform on which they deploy their applications, to access…
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…
I’m excited to share swift-playdate-examples, a technical demonstration of using Swift to build games for Playdate, a handheld game system by Panic.
I’m delighted to announce Swift Atomics, a new open source package that enables direct use of low-level atomic operations in Swift code. The goal of this library is to enable intrepid systems programmers to start building synchronization constructs (such as concurrent data structures) directly in Swift.
Today we’re delighted to introduce the first stable release of swiftly, a Swift version manager that takes the pain out of installing, managing and updating your Swift toolchain.
I’m excited to announce a new open-source project for the Swift ecosystem, Swift Numerics! Swift Numerics will provide the building blocks of numerical computing in Swift, as a set of fine-grained modules bundled together into a single Swift package. My hope is that we can quickly fill some important gaps in the…
We’re thrilled to announce a new open-source package for the Swift on Server ecosystem, Swift Distributed Actors, a complete server-oriented cluster library for the upcoming distributed actor language feature!
Cocoa, the Swift standard library, maybe even your own types and methods—it’s all about to change, and you can help determine how.
Today, we are announcing an exciting development for the Swift programming language: its migration to a dedicated GitHub organization at GitHub.com/swiftlang.
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.
Developer Spotlight is a series highlighting interesting Swift developers from around the world. This post is authored by Ron Avitzur, author of the Pacific Tech Graphing Calculator.
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.
