As always my app ideas comes from: "I can not find an app that does this very simple thing! :( " Let's start coding!

@ScottBerrevoets I have the same problem, and then I ask it to just try and it ask permissions and it works so it apologizes 🙄

Why does Claude keep asking for permission for basic commands sometimes? What am I missing?

🚨This is so much worse than you think. > Amazon laid off 30,000 engineers. Then told the ones who survived that their bonuses depend on how much they use AI to write code. So engineers started using AI to push changes faster, because their paycheck literally depends on it. > And then the site went down. Multiple times. Amazon's own shopping app broke because AI-generated code got pushed to production. > So what did management do? Did they take responsibility for forcing engineers to use AI they weren't ready for? Did they admit they created the problem? No. They called a mandatory meeting and blamed the engineers. > AI is powerful enough to replace engineers, we've been saying that all day. But it's not powerful enough to replace quality control AND common sense all at once. Amazon proved that executives who don't understand AI are more dangerous than the AI itself. And every company rushing to do the same thing is watching this and learning absolutely nothing.

BREAKING: Amazon reportedly holds mandatory meeting after “vibe coded” changes trigger major outages.

🔴This is nuts! 🤯 Grammarly now lets you get an "Expert Review" of your text. Based on the topic, it assigns experts to review it with you. Apparently I'm one of those experts in the tech category, along with many colleagues among hundreds of authors, including some who are dead! WTF… Here you can see a Grammarly clone of me reviewing my own text for my upcoming book. In case you're wondering, no one gave them any permission. I've found @slightlylate, @addyosmani, @rachelandrew, @gradualclearing, @jaffathecake, @brucel, @Paul_Kinlan among others

Just dusted off my 5-year-old project -- rules_applecross now works with Bazel 9, bzlmod and latest of everything. Here's a pipeline of it building a SwiftUI app from Linux github.com/apple-cross-to…

Dijkstra predicted in 1978 how people would feel about #Swift Strict Concurrency checking in 2025.

Trying to reflect on why I was hugely impressed by Claude Codementia early on: it’s my bias towards TUI and its impressive ability to use CLI tools. The good impression faded quickly when I needed to solve real problems.

Had to update my local development workflow a bit since AI agents can do a lot more in parallel now. Decided on a lightweight git worktree wrapper, with simple tmux window management. Wrote about it some more here: scottberrevoets.com/2026/02/17/sca…

“Add an image for each row and watch it die” Every row loads an image from the network. In memory cache, no file cache. URL is random every time (uuid) so cache should always be a miss.

Whoever said SwiftUI List and SwiftData with Query on the main actor can’t perform well, watch this. Close to 4000 items, with relationships that I’m not even prefetching yet. Didn’t even do anything special tbh…

@ScottBerrevoets Yeah, #3 has saved me 2 times already where I asked Claude to do something quick and simple while I work on this other thing over here just to spend the rest of the afternoon trying to get Claude to finish the “simple” refactor

@dev_jac Yeah if I foresee it happening I’ll plan for it but this was specifically for the cases where it catches me by surprise. I guess it’s not different than a developer choosing to refactor but finding rabbit holes 😅

Claude/Codex is in the middle of a medium size refactor in a monolithic app when the “10% context remaining” comes up. What do you do? Keep going? Compact context soon? Start over with a narrower scope? Wrap it up and start over with a new prompt that summarizes progress so far?

Xcode previews and iCloud do not mix. If you sprinkle CloudKit code into your features you break your ability to preview them. So, we built an in-memory version of CloudKit. You get to test more functionality of your features without ever touching iCloud! pointfree.co/episodes/ep351…

Fun fact: it looks like Xcode.app contains Apple Intelligence prompts for certain Apple SDKs, for example - #liquidglass recipe in #SwiftUI. Path: /Applications/Xcode.app/Contents/PlugIns/IDEIntelligenceChat.framework/Versions/A/Resources/AdditionalDocumentation
