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

Published about 8 hours 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).

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.

Codex + Xcode: 3 Workflows You Need

Hey Reader, New video on my workflow for building iOS and macOS apps. GPT 5.2 is insane. It fixed so many problems the first time. Less back and forth from any other model to date. You can fly way faster from idea to prototype in minutes. It's beyond crazy. In a day I can have a working app that solves a key problem.I could never code this fast without AI. It let's you try ideas that you would never consider before due to time constraints.Codex + Xcode: 3 Workflows You Need for iOS/macOS...

Codex Just Changed My Entire Swift Workflow

Hey Reader,Codex surprised me last night. Last night I filmed my unedited workflow with OpenAI's newest model: GPT 5.1 Codex Max. Codex just changed my entire Swift workflow. Codex just fixed a swift bug I couldn't solve (after 12 failed attempts) I literally just talked to it (no complex Plan.md or PRD.md) It explained and executed everything quickly My app is a mix of SwiftUI, AppKit, and Swift. I'm targeting macOS 15+ and Swift 6.2 using AVFoundation and Core ML. The new OpenAI coding...
