👉 Making an app? Build it fast: https://super-easy-apps.kit.com/app-creator GPT 5.4 is here, and this is the workflow I’m using to build real iOS and macOS apps with Codex and Xcode. If AI coding feels overwhelming right now, you’re not wrong. There are too many tools, too many options, and too much noise. In this video, I’ll show you the setup that’s actually working for me. You’ll see the tools I use, how I work with agents, how I debug when Codex gets things wrong, and how I keep improving the workflow over time.
