iphone-duo-displays skillA

iphone-duo-displays is agent-read markdown (skill) from alexey1312/iphone-duo-agent-skill: Use iPhone Duo's hinge, two displays, two front cameras and multiple windows in SwiftUI and UIKit apps. Use when a developer asks about the hinge angle or fold state, onHingeChange or UIHingeInteraction, interactions driven by folding, Split View multitasking or the stacked video layout on iPhone Duo, multiple scenes or windows on iPhone, requestSceneSessionActivation errors on the outer display, UIWindowSceneActivationAction, scene accessories, sceneAccessory, CameraCaptureAccessory, a teleprom.

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 displays, hinge, scenes and cameras

Code: `references/displays-code.md`. Availability: `references/api-availability.md` —
the hinge APIs, `CameraCaptureAccessory`, the direction coordinator and the physical
front camera types need the **iOS 27.1 SDK**, which ships with Xcode 27.1;
`sceneAccessory`, `onAvailabilityChange`, `UISceneAccessory` and
`UIWindowScene.ActivationAction` exist earlier. The hinge reaches you only through
`UIHingeInteraction` / `onHingeChange`: there is no trait, no notification and no
`UIDevice` property. StandBy cannot be verified in the iPhone Duo simulator
(Xcode 27.1 known issues 187708663, 187708767). Which half
carries the outer display and the inner camera, how each pose faces, and what each
camera can do: `references/device-geometry.md`.

## Hinge (Tech Talk 111464, 0:49–2:35)

- SwiftUI `onHingeChange { previous, context in … }`; UIKit
  `UIHingeInteraction { _, update in … }` added to a view with `addInteraction`.
- Reports a status — closed, partially open, fully open (UIKit also `unknown`) — and
  a continuous angle (`UIHinge.angle` is in radians; the SwiftUI sample uses `Angle`).
