Today I'm launching my new app, Hacktivate. It teaches real-world computer science skills through 240 "capture the flag" challenges, and works on iPhone, iPad, and Mac with one purchase. I've poured a ton of love into it, and I'd love to hear what you think 🙌 apps.apple.com/gb/app/hackt...
This Saturday I'm running a YouTube live stream specifically on how to build iOS apps with AI. We'll look at Xcode 26.3, plus Claude Code, Codex, Gemini, agents files and skills, and more. It's going to be packed! Set a reminder here: youtube.com/live/sc6pvW6...

I showed my 12-year-old daughter how to chat to Claude using Xcode's Coding Assistant tab, and she spent the next two weeks building a game. It's out now on the App Store, and she's feeling very proud of herself ✨ apps.apple.com/gb/app/scram...
