SwiftData's #Predicate macro looks like pure Swift but gets compiled into something else entirely. Some things crash at runtime, some silently return nothing, and !value can behave differently to value == false. 😅 https://www.hackingwithswift.com/quick-start/swiftdata/how-to-filter-swiftdata-results-with-predicates

It's #InternationalWomensDay, so there's no better time to celebrate amazing women in the Swift community. Here are some sites I heartily recommend:

It's so interesting watching Apple's Foundation Models evolve. It still really likes to use tools when they are available, but having extra insight into the context window is really helpful ✨ (Also the guardrails are getting better at last!)

I just released a big update for the Swift AI Playbook – updates for Foundation Models in iOS 26.4, yes, but also dynamic data generation, image classification, tabular regression, detecting faces and face details, and sentiment analysis!

I've sent Kickstart TestFlight invites to 10 more people, all of whom emailed me to say they were interested. I made another video of its features – it was 38 minutes, despite me flying through everything quickly 🫠 Hopefully I'll be able to expand the TestFlight further soon!

Join me this Saturday for a live stream all about AI coding for app developers! I'm planning a wide range of topics, so hopefully there's something for everyone 🚀

Sometimes – just sometimes – visiting Reddit pays off.

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: https://youtube.com/live/sc6pvW6vQzA

Next time someone asks me what the UK is like during winter, I’m just going to reply with this screenshot from the BBC News app.
