iPhone and iPad apps built with a coding agent
A coding agent writes React Native screens for iPhone and iPad from an app brief. Source and build output can be reviewed on the Linux codespace. Device testing and App Store publishing take place outside this workflow, with the first version scoped to actions that can be checked against the brief.

First screens and data decisions
A first version can focus on a list, a detail view and a way to save something. The brief records the action for each screen and whether its data lives on the device or in a backend built for the app. Those decisions give the agent a purpose for the first version and provide criteria for reviewing the result before further screens are added.
A kanban card holds the first screen and its data decision. iPhone and iPad share the same React Native codebase. A different layout for iPad’s wider frame can be specified on the card, keeping that requirement in the brief rather than leaving it for later discovery.
Defined actions in a React Native project
The task can specify navigation between the listed screens and the exact action each needs. Examples include saving a note on the device or calling an endpoint and showing the result. These define a concrete behavior for the agent to implement and for the reviewer to compare with the card.
The codespace runs Linux and provides a terminal and VS Code in the browser. Claude Code, Codex CLI, opencode, Cursor CLI, Antigravity and Qwen Code work there with supplied sign-ins or API keys. React Native tooling needed by the project can be installed on that machine.
Source and build review before device testing
This workflow does not run Xcode, the iOS Simulator or a physical device, and it does not publish to the App Store. Review on the codespace covers the agent’s changes against the brief and the build and bundler output in the terminal. These checks remain separate from device testing.
The codespace is billed by the hour while it runs. Its public URL reaches the dev server started by the React Native tooling, while the terminal provides the bundler output. A snapshot supports stopping the machine and returning later; snapshot storage is billed monthly in credits.
Questions about iphone and ipad apps built with a coding agent
- What should a first version of an iPhone and iPad app include?
- Two or three screens with a real action each can provide an initial scope, such as a list, a detail view and a way to save something. The card records whether data lives on the device or comes from a backend.
- Do I need Xcode or a Mac?
- The coding agent writes React Native on a Linux codespace with a terminal and VS Code in the browser. This workflow does not run Xcode or the iOS Simulator, and device testing and App Store publishing are separate.
- How do I check the build without a simulator or a device?
- Build review covers the agent’s changes against the brief and the build and bundler output in the terminal. The public URL reaches the React Native dev server; codespace runtime is billed by the hour.
