OpenAI releases Codex iOS app plugin with integrated simulator and hot-reloading SwiftUI previews

Shoutout to the open source projects behind this:

• Serve-sim powers the streaming simulator by @Baconbrix https://github.com/EvanBacon/serve-sim

• SnapshotPreviews extracts SwiftUI previews by @sentry https://github.com/getsentry/SnapshotPreviews

More of the iOS app loop, now inside Codex.

The Build iOS Apps plugin lets Codex view and test your iOS app in the in-app browser, open SwiftUI previews, and hot reload edits without leaving Codex.

Apple is going to have a tough job next week convincing developers that Xcode is still relevant.

Dropping this right before WWDC is hilarious

I can’t tell if this means Apple will be amazing and build upon it, or if it will be a disappointment in comparison

@OpenAIDevs I think this one is better: https://github.com/tddworks/baguette

@OpenAIDevs bro cmon where iss ittt

@OpenAIDevs @fatbobman hi @OpenAIDevs there is a device pool management lib, hope the team could interate it to Build iOS app plugin

@OpenAIDevs It’s also possible to access them remotely https://github.com/simcast-dev/simcast

@OpenAIDevs coding agents going mobile is a bigger deal than it looks. the "i had an idea on the train and shipped it before my stop" loop is real. the bottleneck was never the keyboard — it was the gap between idea and running code.

@LexnLin @OpenAIDevs imma crash out in about 10 min

This is one of those updates that doesn't look like a big deal at first until you realize how much frustration it removes. Developers used to switch between their editor, simulator, browser, and debugging tools to test a small change. Now AI can write the code, show the app, test it, spot problems, and fix them. Every step and workflow that disappears saves a little time. We're seeing app development go from a pile of different tools to simply having a conversation.

@OpenAIDevs @aToy0m0 I built a small CLI for preparing a GitHub repo before applying for Codex for Open Source.

It checks whether the repo is ready as an OSS project: README, LICENSE, SECURITY.md, CI, and more.

It also generates a starter application draft.

@OpenAIDevs cool

😬😬😬

@OpenAIDevs I read this as "app slop" lmao

@arkuy99 @OpenAIDevs 是的，这一个。非常好用 https://github.com/tddworks/baguette

@OpenAIDevs SimDeck is another great option for viewing and testing your mobile app in Codex.

You can use it for other cool things too, like using GitHub Actions workflows to stream your app to the browser based on PR comments.

@OpenAIDevs This is great news, however the preview part and hot reload only seem to work for non tuilst projects :( Is this planned to be supported? cc @Dimillian maybe you can chime in here? :)

@OpenAIDevs Ahh cool! Is it also available for Android and windows 🤔

@OpenAIDevs THATS IT?

@OpenAIDevs @sentry Shoutout to the codex in-app browser team 🤘
