# Native iOS interfaces

Follow the product's existing iOS conventions first, then Apple platform conventions. A native interface should feel predictable before it feels distinctive.

## Structure and controls

- Use a navigation stack for hierarchy, a tab bar for a small set of top-level destinations, and sheets for self-contained tasks.
- Preserve the edge-swipe back gesture and safe-area behavior.
- Prefer native controls, materials, menus, alerts, sheets, pickers, and text behavior unless the product already has a coherent custom system.
- Keep touch targets comfortable, text scalable, labels accessible, and focus order sensible.
- Account for the keyboard, long content, dynamic type, reduced motion, dark mode, and device insets.

## States

Include the states the task requires: loading, empty, error, success, permission denied, offline, disabled, and recovery where applicable. Feedback should be immediate and should not depend on color alone.

When a simulator or runnable build is available, inspect the relevant device class once and fix observable clipping, overlap, unsafe-area violations, unreadable text, broken navigation, or inaccessible controls. Do not require extra tooling when the environment cannot provide it.
