Production-Ready Valkey Client: valkey-swift 1.0
This month’s highlight is the official 1.0 release of valkey-swift, a Swift client for the high-performance data store Valkey. Guest contributor Adam Fowler, an active open source developer in the Swift-on-server ecosystem, shared the announcement on the Valkey blog.
Valkey is a powerful datastore often used for caching or as a message broker. It emerged as an open source fork of Redis after a licensing change. The valkey-swift library is built from the ground up with Swift 6 and structured concurrency in mind. Every command returns typed responses checked at compile time, and strict concurrency checking catches data races early. Connections and subscriptions are scoped through structured concurrency, ensuring automatic resource cleanup.
The client covers all standard Valkey commands, auto-generated from Valkey’s own command specifications to stay in sync with server updates. Previously, the de facto Redis client was RediStack, which relied on pre-concurrency patterns. Retrofitting structured concurrency would have been awkward, and new features in valkey-swift would have been infeasible. Combined with the Redis licensing shift and the creation of Valkey, it was the right moment for a clean slate.
If you’re building server-side Swift and need a fast key-value store, add valkey-swift via Swift Package Manager. A migration guide is available for RediStack users, and complete documentation is online. Contributions are welcome on GitHub.
Embedded Swift Takes Center Stage at try! Swift Tokyo 2026
The try! Swift Tokyo 2026 conference featured two notable talks on Embedded Swift:
- Getting started with Embedded Swift – A beginner-friendly introduction that covers writing Swift with embedded simulators and code examples to run Swift on devices like the Game Boy Advance.
- Learn by Building: Bare-Metal Programming with Embedded Swift – A deeper dive into bare-metal development, with five sample projects for the Raspberry Pi Pico that you can follow along with.
