1. Valkey-Swift 1.0: A Modern Swift Client for Valkey and Redis

The open-source Swift ecosystem just got a powerful new tool: valkey-swift has reached its 1.0 release. Developed by Adam Fowler and contributors, this client is built from scratch for Swift 6, embracing structured concurrency and strict compile-time checks. Every Valkey command returns typed responses, eliminating runtime surprises, and connections automatically clean up via scoped concurrency. The library supports all standard Valkey commands, auto-generated from Valkey’s own specifications to stay in sync as the server evolves.

If you’re currently using RediStack with Redis, valkey-swift offers a migration guide to help you switch. The library is equally compatible with both Valkey and Redis, making it a future-proof choice for server-side Swift developers who need a fast, reliable key-value store. Add it via Swift Package Manager and start building today.

2. Getting Started with Embedded Swift – A Talk for Beginners

At try! Swift Tokyo 2026, attendees were treated to two standout talks on Embedded Swift. The first, Getting Started with Embedded Swift, is a short and accessible introduction perfect for those new to embedded development. It covers using embedded simulators to run Swift code on devices like the Game Boy Advance, complete with code examples that let you follow along. The talk demystifies the barriers to entry, showing that you can write Swift for hardware without an extensive electronics background.

Whether you’re a hobbyist or a professional exploring IoT, this session provides a clear path to writing Swift in resource-constrained environments. The recording and sample code are available online, so you can start experimenting right away.

3. Bare-Metal Programming with Embedded Swift on Raspberry Pi Pico

The second Embedded Swift talk at try! Swift Tokyo 2026, Learn by Building: Bare-Metal Programming with Embedded Swift, takes a deeper dive. It walks you through five bare-metal examples designed for the Raspberry Pi Pico, a popular microcontroller board. From blinking an LED to more advanced peripherals, each example is fully documented and ready to try.

This talk is ideal for developers who already have a basic understanding of Embedded Swift and want to explore hardware interaction without an operating system. By following the sample code, you’ll gain hands-on experience with direct memory access, interrupts, and other low‑level concepts, all expressed in Swift’s safe and expressive syntax.

4. Live Q&A on Swift Concurrency with the Experts

Want to master Swift’s concurrency model straight from the people who built it? A live online Q&A session featuring Swift engineers covered topics like async/await, actors, and structured tasks. Participants could ask real-time questions about common pitfalls, performance best practices, and the future direction of concurrency in Swift.

This event is now available as a recording for those who missed it. Whether you’re dealing with data races, task groups, or custom executors, the insights shared are invaluable for writing safe and efficient concurrent code. Be sure to check it out—it’s a rare opportunity to learn directly from the language’s designers.

5. Advanced Techniques for Working with Optionals in Swift

The Nil Coalescing team published a new video titled Advanced Techniques for Working with Optionals in Swift. While optionals are a fundamental part of the language, many developers only scratch the surface with basic unwrapping. This video explores lesser-known options like pattern matching, the ?? operator in combination with closures, and strategies for chaining multiple optionals without force unwrapping.

It’s a short but packed resource that will help you write cleaner, safer code. Whether you’re a seasoned Swift developer or still building your skills, these techniques can reduce boilerplate and eliminate common runtime crashes. The video is freely available on their channel.

Conclusion
April 2026 has been an exciting month for Swift, with the launch of valkey-swift marking a milestone for server-side development, and Embedded Swift taking big leaps forward. The community continues to share knowledge through talks, Q&As, and video tutorials. Whether you’re building a new backend service or programming a microcontroller, these updates give you the tools and insights to succeed. Stay tuned for more next month!
