Build and debug iOS and macOS apps.
Codex works great on Apple platform projects when each pass has a build, run, or simulator loop attached to it. These use cases are helpful when you are building new or existing iOS and macOS apps and need to iterate on the UI and debug issues.
Build the app shell
Ask Codex to scaffold iOS and macOS apps with repeatable build loops. The Mac shell use case goes deeper on sidebar-detail-inspector layouts, commands, settings, and other desktop-native structure.

Refactor iOS SwiftUI screens
Use Codex to split large SwiftUI views without changing behavior, then move selected iOS flows to Liquid Glass when the app is ready.

Expose iOS actions to the system
Leverage Codex to identify the actions and entities your app should expose through App Intents, so users can reach app behavior from system surfaces.
Debug your app
Have Codex reproduce bugs in Simulator or add telemetry to your macOS app to help you debug and fix issues.
