1# Native development

2 

3Build for iOS and macOS, refactor native UI, expose app actions, and verify your work with the right loop.

4 

5Codex works great on Apple platform projects when each pass has a build, run, or simulator loop attached to it.

6These 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.

8## Build the app shell

9 

10Ask 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.

16## Refactor iOS SwiftUI screens

17 

18Use Codex to split large SwiftUI views without changing behavior, then move selected iOS flows to Liquid Glass when the app is ready.

23## Expose iOS actions to the system

24 

25Leverage Codex to identify the actions and entities your app should expose through App Intents, so users can reach app behavior from system surfaces.

29## Debug your app

30 

31Have Codex reproduce bugs in Simulator or add telemetry to your macOS app to help you debug and fix issues.
