SwiftUI’s concurrency annotations express its runtime semantics. Look, there’s a nice YouTube video about it: youtu.be/Ttxz8bVvX3s #WWDC25

WWDC25: Explore concurrency in SwiftUI | Apple


Out of nowhere I intentionally used the dc command for the first time today.


Unexpected usage of sqlite: to get a strict proleptic Gregorian calculation of seconds since unix epoch, use a query like `SELECT CAST(ROUND( (julianday(?) - 2440587.5) * 86400.0 ) AS INTEGER);` instead of Foundation's Date.

It’s almost time! Tomorrow I’m going to be giving a talk that’s a deep dive into SwiftUI performance. You can watch live here: developer.apple.com/events/view/MW…


Type vimtutor in a terminal.

Two weeks to go! If you’re interested in seeing me do a deep dive on SwiftUI performance, register with the link:

Some exciting news: On October 30, I'm going to be talking about SwiftUI performance and you can stream it live! Register to see my talk and some other great ones about foundation models and battery life optimization too: developer.apple.com/events/view/MW…



Edge of Tomorrow (2015) is a movie about Claude Code.


TIL what my car looks like after visiting 3 national parks in a row.


Repost di Daniel Duan

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.

New in Xcode 26 Beta 7: Users can now log into their Claude account from Xcode. Generate code and documentation, automatically fix errors, and create inline playgrounds using coding intelligence features in Xcode, powered by Claude Sonnet 4.

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.
