TIL what my car looks like after visiting 3 national parks in a row.
Xcode developers, rejoice! Claude account support is now enabled, adding to the existing support for ChatGPT (now including GPT-5). This changes how I write code, liberating me to focus on the fun parts! Check it out in Xcode 26 beta 7.

Apple's JS-rendered docs leave AI tools staring at blank pages. I got tired of Claude writing broken SwiftUI code, so I built sosumi.ai Swap developer․apple․com → sosumi․ai in URLs to get clean, AI-readable Markdown. Or connect via MCP.
why did they call it waymo and not google drive
One Piece is basically Journey to the West except the monkey is a family, and one of them wants to be king.
Today we’re excited to launch Bitrig. Bitrig builds native Swift apps just by chatting with AI. In minutes, and with no code required, you can create an app and deploy it directly to TestFlight. youtu.be/e-DqSVEI50w #Swift #SwiftUI #BuildInPublic
The team that built the Foundation Models framework is hiring! Join us to create the best LLM APIs, both for app developers and for Apple teams. jobs.apple.com/en-us/details/…

Announcing sourcekit-bazel-bsp: iOS development in IDEs like Cursor / VSCode, for Bazel projects! It's in very early stages, but I'm already very excited about the potential this has for the iOS community! github.com/spotify/source… #iosdev #swiftlang
Working with models for coding tasks will make good programmers better technical communicators.
TIL AI is not advanced enough to handle a zip file containing about 20 years of lease contracts, for the purpose of extracting the starting date, address, and name of the places into a spreadsheet.
Tfw you add a log, wait for build-and-run, only to find out the value you are printing is a ObjC enum.
When the SwiftUI WebView API landed in iOS 26 I was happy. And now I'm even happier 🤩 - WebPage conforms to Transferable - All the load APIs return AsyncSequence so you observe the whole navigation - load() has an optional URL overload, for when URLRequest is too much So good!
Don’t do anything in deinit other than releasing resources. Just don’t. #swiftlang
