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: WWDC26 highlights At its WWDC26 conference, Apple provided an update on its adoption of Swift and made a variety of new Swift-related announcements. Some highlights: During the Platforms State of the Union, Apple announced that parts of the core operating system kernel are being written in Swift for upcoming releases. What's new in Swift featured changes in Swift since last year, including a preview of what's coming in Swift 6.4, like up to 4x faster URL parsing and support for async code in defer blocks.
