What's new in Swift: June 2026 Edition
Swift.org ·
Welcome to “What’s new in Swift,” a curated digest of releases, videos, and discussions in the Swift project and community.
June was an exciting month for Swift, featuring announcements at WWDC and community events around the globe. We invited the organizers of one of them to share with us:
Hey, it’s Mikaela and Adrian. We are organizers of CommunityKit , a community-organized conference that takes place the same week as WWDC, and iOSDevHappyHour , a monthly online meetup that keeps the community connected year-round. This is our fifth year coming out to Cupertino, and we love being able to create a place for the community to thrive, no matter where developers live.
CommunityKit brought together over 250 developers in real life to geek out over the announcements, stay for the community and vibes, see what everyone is creating, and learn from each other. Some of the highlights from this year’s event were the Indie Fair, where developers showcased their apps; the Watch Party, our annual gathering to watch the keynotes together; and Make Something, Ship Nothing, a hands-on postcard-making hangout to close the week. This year we also introduced workshops, including “Inclusive by Design” by Danielle Lewis, and for the Swift community: “Write Faster, Smarter Swift” by Paul Hudson.
We can’t wait to hear about what everyone builds and brings to next year’s Indie Fair, and hope to see you at CommunityKit and iOSDevHappyHour!
Now on to other news about Swift:
At its WWDC26 conference, Apple provided an update on its adoption of Swift and made a variety of new Swift-related announcements. Some highlights:
Build real-time apps and services with gRPC and Swift walks through integrating an iOS app and gRPC service using live race data from a go-karting league. See if you can spot where the track is located. 👀 Want to learn about Swift macros with hands-on tutorials? Stewart Lynch published two videos with sample code to follow along: Swift Macros Demystified: Build a Freestanding Expression Macro , and Swift Attached Macros: Build a Real-World Member Macro from Scratch . A new 10-minute Embedded Swift demo uses an accelerometer and the XIAO ESP32-C6 to control a Swift bird that glides across a mini OLED screen. No soldering required! Community highlights Swift Package Index joined Apple and remains open source. The team says they’re working together to build a comprehensive package registry for the Swift community.

This group will work on a unified networking stack for Swift, layered from low-level I/O primitives, through common protocols, to a modern HTTP client and server API. New package releases New Swift bindings for the OkHttp Java library were released. If you’re using Swift on Android and looking for an HTTP client this may be useful. The project was generated with swift-java . Kiln is a new documentation engine written in Swift. Built to replace MkDocs-based documentation sites, it gives more options for the Swift community to render docs, in addition to the DocC project which is used for the official Swift documentation. You can see Kiln in action at the Vapor documentation . Version 0.4.0 of Elementary UI was released, a frontend framework for running Swift applications natively in the browser.
