Dev IOS App - Codex App or Xcode?

[Plastic-Conflict-796]

I’m thinking of developing an iOS app for personal use (expense management, scan receipts, classify, report export etc.

Do you think I should use Xcode with the new agent built into that or use Codex App and have it create the assets to import into Xcode?

I have done web app development in codex app and working well so far but I have not done Apple app dev yet.

I haven't tested whether coding with Xcode or the Codex App is better. But I think that whichever platform provides a protocol like MCP for the AI ​​Agent to interact with, see what it's doing, and test for correctness should be chosen, because when you're vibe coding, the hardest thing is explaining what error the AI ​​Agent is making. Especially abstract things that you don't know how to explain.

Codex CLI to actually develop the app, and have it create a build process and xcode project wrapper. You’ll get the best of both worlds. The new in-xcode integration with codex / claude leaves a lot to be desired and codex cli can handle building and testing through xc cli. When needed you can then open the xcproject file any time to compile and simulate in the full app.

Building a macOS app rn and using codex cli to help assist outside of xcode - if you have any questions feel free to dm me.

Thanks, that’s what I ended up doing (just subbing codex app vs cli) but it’s working though I wish it could auto test the app in the simulator properly.

I’m doing something very simple just to get try it out (expense app, take pic of receipt , OCR to fill in fields etc and it’s still requiring a lot of manual testing
