Swift Effect is now in public preview! it is an architecture-agnostic effect system that makes side effects (such as I/O, networking, randomness, concurrency) controllable, composable, and testable without forcing structural changes to your application code. github.com/Alex-Ozun/sw... #swiftlang

🇪🇺👀

I love what Tauri has done, a lightweight version of Electron, where you author the backend code in Rust. But while I love Rust, I do not love it for app building, and I wanted to have that HTML-model for programming but available in Swift. 1/2

Working with @signalgaining on some cool new libraries! Coming to a WendyOS device near you shortly! github.com/wendylabsinc... What else are we cooking?

Holy! No shot! That is a good present

This is xMas for #Swiftlang developers too. The Visual Studio Code extension for Swift is now available on Open VSX Registry open-vsx.org/extension/sw... You can now install it as easily as other extensions from code-oss-based IDE, such as Kiro, Windsurf, Cursor etc. Happy coding !

Building the future is exciting!

Latest round of updates in the Swift for Wasm ecosystem is here! forums.swift.org/t/swift-for-... #Wasm #WebAssembly #WASI #SwiftLang #JavaScript

Wow! The first SwiftGodot-based game is on the AppStore: apps.apple.com/us/app/termi...

📢 #Swiftlang is headed to FOSDEM with a Swift pre-FOSDEM Community Event on Fri 30 Jan (12-6PM) in Brussels AND we have talks at various devrooms ! 🤗 Check out how we're showing up: swiftlang.github.io/event-fosdem/ Things to know – 📌 RSVP here: s.apple.com/dn5G2r2Ns6 📌 CFP is now open til 5 Jan

The @arcticconference.bsky.social was one of the best weeks I had this year, so I'm happy to return to Oulu in February. Not as a speaker, but just to come back and enjoy one of the best conferences out there 🫶 If you haven't bought your ticket, go treat yourself with an early Christmas present!

Exploring the Swift SDK for Android: updates on ongoing progress! www.swift.org/blog/explori...

Want to meet up about Swift? Android, Linux, Emebdded or something else? Find me at FOSDEM or @arcticconference.bsky.social ! More events added to the list very soon.

Dijkstra predicted in 1978 how people would feel about #Swift Strict Concurrency checking in 2025.

CALL FOR PAPERS 📑 For the swift community event the day before #FOSDEM is now open!! See you there 😊 #swiftlang #swift #oss

Preparing to ship my first Swift for Windows executable!

@arcticconference.bsky.social is going to be great! I'm eager to share some of the incredible advancements around Swift with you all. And such an incredible location too!

Going to improve mDNS support in Swift today. Stretch goal, CI for Windows.

Setting up Windows CI for my Swift PRs! Running into a weird clang bug - but we'll find a fix 💪

🎉 Swift-Configuration integration in Hummingbird! github.com/hummingbird-...

⚙️ Swift Configuration 1.0 is here! 🎉 No more juggling environment variables, config files, and command-line flags separately. One unified, type-safe API to read configuration from any source, and swap providers without refactoring your code. More here... www.swift.org/blog/swift-c...

Brag of the day; all of these @SwiftLang deps working on Windows?! Time to update their CI.

See you in 3 hours! www.youtube.com/watch?v=-iYx...

Thanks Espressif and M5Stack for the goodies! I'm looking forward to bringing more Embedded @swift.org libraries to your platforms!

My fave tip for dev #swiftlang -> Linux, check how your Swift package compiles while on your mac w/ container: container run -it -c 4 -m 8g \ -v "$(pwd):/src" -w src/ \ swift:6.2 sh -c "swift build" (runs a Swift 6.2 image, gives it 4CPU and 8GB, mounts your PWD as "src", and builds)

Swift Configuration is now in alpha. 🥳 github.com/apple/swift-...

🎄This year's Advent of Code promises fun coding challenges for all! And if you haven't tried Swift before, it's a great way to get started. Join the Swift challenge board here: forums.swift.org/t/advent-of-... #AdventOfCode

Next Swift Server Workgroup meetup coming December 9th at 10:00 PST / 18:00 GMT / 19:00 CET! www.youtube.com/watch?v=-iYx...

I can't wait to see where the community takes Swift on embedded platforms, microcontrollers like Doug G and Rauhul talk about here or even bigger and at the edge. www.swift.org/blog/embedde...

Check out this excellent @swifttoolkit.bsky.social conversation with Pierluigi Cifani on #Swiftlang for #android. www.swifttoolkit.dev/posts/dc-pier

This would be so nice to improve the developer experience around non-Swift packages. forums.swift.org/t/expose-sys...

Next Do iOS is changing gear, looking at multi-platform development with Swift. We have @joanniso.bsky.social with “Cross-Platform Swift - Reusing Code between iOS and Android” #doios

How easy is it to learn about Swift on the server and has much changed in the year since Mikaela Caron gave the community a challenge to improve things? Well this year she's back to give us an update! youtu.be/dAa9HmJEGfA

My talk from #ServerSideSwift is live!! And I’m announcing a new website I’m still working on called LearnSwift .space to provide more content for the Swift community on using Swift outside of Apple platforms LearnSwift.space

Swift on Android is going strong, some thanks to the existing Swift Server ecosystem being able to adapt quickly! However, we’ve also got much more brewing for Linux apps! Stay tuned!

2️⃣ Swift Student Challenge returns Calling all student developers! Submissions open February 2026. Start preparing now with code-along sessions and new tutorials. 🧑‍🎓https://www.apple.com/newsroom/2025/11/developers-decode-their-journeys-from-app-ideas-to-app-store/

3️⃣ AWS officially adopts Swift Lambda Runtime Amazon is now officially hosting the Swift AWS Lambda Runtime. This is a game-changer for building fast, efficient, and scalable serverless applications with Swift: now backed by AWS. github.com/awslabs/swif... #AWS

1️⃣ Swift comes to FreeBSD Swift is now available in preview for FreeBSD 14.3 and later. We want your feedback, bug reports, and contributions to make Swift great on FreeBSD! 🧑‍💻Read the announcement here: forums.swift.org/t/swift-on-f... #FreeBSD

Indie developers now have more tools in their toolkit for building with Swift across platforms, thanks to Skip. Exciting to see a Swift community member building a business with the open source Swift SDK for Android. skip.tools/blog/skip-fu... #Android

Just had a blast in the #swiftlang #android workgroup! A turn up of 10 new people looking to collaborate on making this happen 💪 This effort is completely open! If you're interested too - join our community!

💪 8 PRs for Swift libraries to support Windows and counting. Let's make this happen!

Once I'm done helping run Swift on Windows, I'll focus on MLX for Linux/Windows!

What's this? A Hummingbird app!! On Windows?!

Almost got it working! #hummingbird #swift #windows

Thanks to those who shared their amazing insights: @joanniso.bsky.social, Bruno Valente Pimentel, Natascha Fadeeva, Matteo Manferdini, Tomasz Lizer, Uladzislau Volchyk, @danielsaidi.bsky.social, @massicotte.org, Pierluigi Cifani and Wes Wickwire

When you are an Android developer, every day is Xmas! I personally wouldn’t use this for UI yet, but it is going to be great to share more code. Like having Android be a supported platform for amazing libraries you were itching to use every day, like SwiftGodot or SwiftTerm :-)

Curious for Swift on Android? There was a talk on it recently at NSSpain by Pierluigi. He's already been using Swift on Android for a while - so experienced in the topic! www.youtube.com/watch?v=EIGl...
