I really miss the old days of iOS development. We used to talk about frameworks, new APIs, third-party libraries, architecture, and how to solve real problems. There was genuine enthusiasm. When someone launched a new app, it felt different. AI made a lot of things easier, but it also took some of that feeling away.

So… we tried today in the Valencia Apple Store. I liked the factor size of the small screen. It’s not heavy in the hand but I felt this was really hot just after using the camera only a few minutes. Maybe next gen… my iPhone 17 Pro now feels like a Max. 😅

We're making Shopify's mobile apps self-healing. Agents watch production 24x7 for new crashes, reproduce them, write and verify a fix, then generate a short video explaining the root cause and the fix. Much faster to digest than the usual wall of text. An engineer then just reviews and ships it.

No iPhone 27.x simulators available with latest Xcode version? Just try this (the accepted answer): origin-devforums.apple.com/f… It's due to the `cryptex` format of the .dmg images used since iOS 18. 🤷🏻‍♂️

Throughout the years we’ve recieved a lot of letters from the people, who haven’t been able to attend ARCtic. Mainly people have told us just to keep up the good work and expressed their FOMO, but last week we got one with a bit different tone. This letter was so special that we decided share it with you in a form of a familiar tune (turn on the sound if you can).

I've been playing today with @twannl new @rocketsim_app skill with Codex and I should say the the experience I was looking for since time ago. 😍 This reduces the gap between your idea and the product and makes iteration faster by just selecting the element you want to change.
