iphone-duo-layout is agent-read markdown (skill) from alexey1312/iphone-duo-agent-skill: Use this skill when an app's layout or geometry breaks or wastes space on iPhone Duo's foldable inner display: layouts that should become multi-column in regular × regular size classes, NavigationSplitView or TabView sidebars on the inner screen, a phone-width column stuck in the middle, safe-area insets that differ left and right, content or floating controls crossed by the hinge in book or tabletop pose, the FaceTime camera covering UI, or video letterboxing on the wide inner screen. Also use .

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# iPhone Duo layout

Layout on iPhone Duo is ordinary adaptive layout pushed further: two displays with
different size classes, a hinge that divides the inner display when folded, and
cameras that occlude part of it. Start from system containers — most of the behavior
comes for free — and add custom work only where a container cannot express it.

Code: `references/layout-code.md`. Availability: `references/api-availability.md`
(reserved regions, arrangements and `ContentMarginGuide` need the **iOS 27.1 SDK**,
which ships with Xcode 27.1 — on that toolchain they need a deployment-target gate,
not a blocked entry). Physical facts — display sizes, where the cameras and fold sit,
poses, drawing mockups: `references/device-geometry.md` (never a layout input).

## 1. Size classes, not devices (Tech Talk 111461, 2:46)

- Outer display: like other iPhones. Inner display: regular × regular — room for
  sidebars and multiple columns.
- Drive layout from `horizontalSizeClass` / `verticalSizeClass` (environment in
  SwiftUI, trait collection in UIKit) and from the container size; never from
  orientation or idiom (`iphone-duo-adaptivity-audit` owns removing those).
