Codex Just Changed My Entire Swift Workflow
|
Last night I filmed my unedited workflow with OpenAI's newest model: GPT 5.1 Codex Max. Codex just changed my entire Swift workflow.
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 model is incredibly fast and way more efficient on tool calls (reading files, editing, coding, etc). If you have ideas for apps and want to get started, now is the time to start playing with codex and ChatGPT. I have been a ChatGPT Pro plan subscriber all year ($200/month), and it is amazing. Access to ChatGPT 5.1 Pro is a new level of intelligence that you cannot get anywhere else. You can just do things. Having a coding partner allows me to try things that would have been impossible before (with a family, kids, exercise, work, and sleep). It feels like I have an excellent pair programmer who can help execute on all my ideas. ChatGPT Pro is worth $200/month for me because I get the time back. If you’re curious, you can start with the $20/month Plus tier just to see if it helps your workflow. You won't regret it! Want to work with other like minded people? I'm going to launch an App Launch Community in January 2026. Signup if you want to work with me and other developers who want to finally publish apps for themselves (or to build a business that generates side income). Hit reply and tell me about your app idea. I read every email. Talk soon! Paul Solt P.S. I'm building a new studio office. Check out my new space and the insane sound isolation. It feels like a different world in that room. |

Hey Reader, Agents write better code when they can read docs instead of guessing from memory. A 2026 paper found up to a 20% improvement in first-try code accuracy when models were given the right programming context. So what do you do with that? Don’t rely on the agent to know everything from their training set. Instead, provide tools or local docs that they can reference. Your local docs should include sample code so agents can use the code correctly (the first time). If you’ve ever read...
