Swift Developers Land Production-Grade Valkey Client: valkey-swift 1.0 Goes Live

The Swift on server ecosystem reached a milestone with the release of valkey-swift 1.0, a production-grade Swift client for the Valkey datastore. Adam Fowler, open source developer and lead author, announced the release on the Valkey blog today.

“valkey-swift is built from the ground up with Swift 6 and structured concurrency,” Fowler said. “Every Valkey command returns typed responses checked at compile time, and strict concurrency catching data races before production.”

Valkey, an open source fork of Redis, is a high-performance datastore commonly used as a caching layer or message broker in server applications. The new client supports every standard Valkey command, auto-generated from Valkey’s own command specifications to ensure compatibility as the server evolves.

Connections and subscriptions are scoped through structured concurrency, meaning resources clean up automatically. The library currently covers all standard commands and is targeted at Valkey servers but works equally well with Redis.

Background

Before valkey-swift, the de facto Swift client for Redis was RediStack, built on pre-concurrency concepts. Retrofitting structured concurrency would have been awkward, and some new features in valkey-swift were infeasible under that design.

Around the same time, Redis changed its licensing structure, prompting the creation of the open source fork Valkey. “It felt like a good time to make a clean break and build a new library,” Fowler added.

What This Means

Server-side Swift developers now have a modern, safe, and efficient client for one of the most popular datastores. valkey-swift leverages Swift 6’s concurrency model to eliminate data races at compile time, reducing runtime errors and simplifying code maintenance.

For teams using RediStack to connect with Redis, a migration guide is available. The library is ready to add via Swift Package Manager, with complete documentation and contributions welcome on GitHub.
