Always makes me happy to see these projects, which both propel the project forward and boost the careers of some amazing new contributors! swift.org/blog/gsoc-2026-sho… #gsoc
Starting today with the 27.3 betas, the new Siri AI Developer Preview enables apps to integrate with Siri AI. New APIs that you can build with, documented here: developer.apple.com/document…
Love seeing that it's helping folk! xitter.gq/JoshuaNewton/status/21…
The AI world we live in offers the joy of creating hyper-personalized apps. I wanted an app to truly study Beethoven's piano sonatas, including comparing recordings, taking notes, and viewing scores. So I created a beautiful Mac app in an evening with Xcode. Feels like magic.
ALT A SwiftUI app that provides access to Beethoven's piano sonatas.
Some fun for the weekend: Simon Leeb's talk on ElementaryUI, an experimental server-side web framework built with Swift and SwiftWasm. Check out the video: youtube.com/watch?v=OmQ881sO…
Version 0.9 shipped today 🎉
If you know Swift, the web sample below will feel very intuitive.
Xcode 27.2 ships with a new skill for agents to work with Instruments, as well as an update to the SwiftUI specialist skill. Love that my apps can get better just by upgrading!

I haven't been this excited about smartphone apps since 2008.
The iPhone Duo seems to have galvanized the developer community, leading to an explosion of novel concepts and new designs. Feels like the iPhone 3G all over again, and I'm *very much* here for it
It's not a new feature, but everyone I've shown this Apple Watch tip to has fallen in love with it. It's a great, subtle way to check you're not running late for a meeting while staying focused on a conversation. support.apple.com/guide/watc…
"The latest version of NetNewsWire for iOS supports iPhone Duo... We were already using standard controls... and paying attention to size classes... We built the app using Xcode 27.1 and the default iOS SDK that comes with it, and that’s it." netnewswire.blog/2026/10/16/…

Congrats to the team! Amazing to run a model of Muse Spark Open's caliber and scale this efficiently, right from your desk. Mac Studio keeps pushing the boundaries of on-device AI!

If you're using Claude Code, Codex or Cursor to prototype for the iPhone Duo, make sure to run this command, with the argument underlined in red
Because Xcode 27.1 ships with updated coding skills that specifically detail how to handle app resistibility for the iPhone Duo
