Audit and port an iOS app to iPhone Duo, Apple's first foldable iPhone. Use when asked to support, adapt, prepare, test, or review an app for iPhone Duo, foldable iPhone, the inner/outer display, device poses, or the fold. Entry point that routes to the layout, bars, hinge/scenes, camera, and design skills.

Build layouts that adapt to the iPhone Duo fold using reserved regions, division and occlusion regions, displacement patterns, and the split and overlay ArrangementView containers. Use when content or controls land in the fold, when building a split-like or overlay layout, or when custom manually-positioned UI must avoid the hinge or the under-display camera.

Review or design an iOS interface for iPhone Duo's poses — closed, open, book-folded, tabletop and tent — covering side-mounted controls, asymmetric layouts, fold avoidance, sheets, and how to use the inner display well. Use for design critique, mockup review, or deciding what a screen should look like on a foldable iPhone rather than how to code it.

Adapt toolbars, navigation bars and tab bars for the vertical axis on iPhone Duo — item ordering, symbol vs text representations, axis behavior, overflow menus, visibility priority, and when to opt out. Use when toolbar items look wrong, overflow too early, or need to move to the side on the outer display.

Use the iPhone Duo hinge angle for interactions and effects, support Split View multitasking and multiple app scenes, and pair UI across both displays with scene accessories including CameraCaptureAccessory. Use when building fold-driven effects, multi-window support, or dual-display experiences.

Build camera capture for iPhone Duo's two front cameras — the virtual front camera, the inner under-display and outer ultra-wide devices, AVCaptureDeviceDirectionCoordinator, preview mirroring and video gravity, and dual-display capture. Use when an app captures photo or video and must handle the device opening, closing or flipping.
