The Growth of the Swift Server Ecosystem

September 23, 2025

Nearly ten years ago, Swift was open sourced and an official runtime for Linux was released. I’ve been involved with Swift on the server since almost the very beginning, originally picking it up as a way to use a language I really enjoyed for backend development. In that time Swift has come a long way, with stability across platforms, a burgeoning ecosystem and many success stories. It’s matured into a great option for highly-scalable server applications, websites, and lambdas.

Plotting a Path to a Package Ecosystem without Data Race Errors

July 1, 2024

Swift 6 introduces compile-time data race safety checking for any code that opts in to use the Swift 6 language mode. While individual modules can adopt this mode incrementally and independently of their dependencies, the full benefit of runtime data race safety is only realized when all modules have opted in. Therefore, the quick adoption of Swift 6 language mode across the ecosystem of open-source packages will play a key role in advancing data race safety across the entire Swift ecosystem.

Introducing the Benchmark Package: Complementing Unit Tests with Performance Checks

March 20, 2024

In the world of software development, the old adage “make it work, make it right, make it fast” serves as a guiding principle for creating robust, efficient applications. This journey starts with ensuring that our code functions as intended, a task where unit and integration testing have proven indispensable. However, ensuring functionality is only part of the equation. The true measure of an application’s excellence extends into its performance - how fast and efficiently it operates under various conditions. Herein lies the critical but often overlooked third step: making it fast.

Iterate Over Parameter Packs in Swift 6.0

March 7, 2024

Parameter packs, introduced in Swift 5.9, make it possible to write generics that abstract over the number of arguments. This eliminates the need to have overloaded copies of the same generic function for one argument, two arguments, three arguments, and so on. With Swift 6.0, pack iteration makes it easier than ever to work with parameter packs. This post will show you how to make the best use of pack iteration.

Swift 5.10 Released

March 5, 2024

December 11, 2024

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.

Embedded Swift Improvements Coming in Swift 6.3

November 17, 2024

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 in the Embedded Swift vision document.
