OpenAI Brings iOS App Loop Into Codex With New Build iOS Apps Plugin

OpenAI has released a Build iOS Apps plugin for Codex, its autonomous coding agent, closing the iOS development loop without requiring developers to leave the tool. The plugin lets Codex view and test an iOS app directly in the in-app browser, open SwiftUI previews, and hot reload code edits in place — keeping the full build-preview-iterate cycle inside a single environment.
