I Tried to Break GPT-5.2 — It Kept Working (SwiftUI + macOS)

Published 8 months ago • 1 min read

Hey Reader,

New Codex models are incredibly good for Swift code for iOS/macOS apps. You can easily install codex via here

Just open Terminal/Ghostty and type: npm i -g @openai/codex

Using codex, you can use simple language to talk to your agent. See the first video if you want a breakdown on the tools I am using, and some of the rules in my agents.md rule file.

Spider Warning: if you're afraid of spiders, you won't want to watch these videos. I am making a dangerous spider identification app, because I want to keep my kids safe (and it's interesting playing with Core ML and Machine Learning).

4. 🔴 LIVE Recording: GPT-5.2 Codex vs Real-World ML App (Spider Detection)

There's a lot to learn, but GPT 5.2 changes the game. It's very easy to direct and it just works. Not constant rework you might have seen in Claude Code (4.5, etc), GPT 4, GPT 5.0, or even GPT 5.1.

You won't want to yell at GPT 5.2, because it is higher level intelligence and it will follow your rules to a point. It's a super effective, super hard working, coding agent who can fix and solve problems on your behalf.

P.S. Need help with your iOS/macOS apps? Go here to learn about my upcoming App Launch Community. If you have an idea for an app, Codex is the enabler you've always wanted.

More details in January 2026. I'll be sharing what's working for me.

Super Easy Timer starts in one tap on iPhone

My timer app finally works on iPhone

Hey Reader,You can now use Super Easy Timer on iPhone. I had my agents use the Mac app as a reference and extracted a shared library of code using the Swift Package Manager (SPM). This is the brains of my timer app, and it's shared across iOS and macOS. The MVP worked last week, but it wasn't reliable until I added AlarmKit. That allows timers to persist even if the app is force-quit or the iPhone is locked (just like Apple's system alarms). That was my biggest blocker, and now that it's in,...

3,158 downloads over the last 90 days because of Apple featuring my app

Apple featured my app. I made $0.

Hey Reader, Apple featured Super Easy Timer on the front page of the Mac App Store. 3,158 downloads. $0 revenue. That's on purpose. What got me here? Fixing all the papercuts in the original timer app and creating a better onboarding experience caught Apple's attention. That made them feature my app on the front Discover page and on the Work tab in the Mac App Store. Over the past two months, I made huge improvements to the UI and unlocked the ability to use a timer on top of every single...
