Find and fix legacy screen, orientation, idiom and lifecycle code that breaks on iPhone Duo's inner display and in other iOS 27 resizable environments (iPhone Mirroring, iPhone apps on iPad, Split View). Use when a developer asks about UIScreen.main or mainScreen, screen bounds or scale, interfaceOrientation or UIDevice orientation checks, userInterfaceIdiom layout forks, keyWindow or connectedScenes.first, migrating from app lifecycle to UIScene lifecycle (required with the latest SDK)…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# iPhone Duo adaptivity audit The foundation for everything else: an app that decides layout from the screen, the orientation or the idiom is wrong on iPhone Duo before any foldable-specific work begins. ## Facts this skill relies on - The **outer display** behaves like other iPhones; the **inner display** is regular width × regular height. (Tech Talk 111461, 2:46) - The inner display **does not honor supported interface orientations**; in iOS 27 supported orientations are a preference ignored in resizable environments, and iPhone Mirroring always reports portrait. (111461 2:46; WWDC26 278 6:50) - Referencing the **main screen is ambiguous on a two-display device** and deprecated (the iOS 27 SDK header marks `mainScreen` deprecated). (111461 3:57; 278 2:51) Concretely: the iPhone Duo simulator's own profile names the **outer** display as `main-screen-*`, so an app that asks for the main screen gets the smaller of the two whichever display it is actually on. (`references/device-geometry.md`, measured) - The **user interface idiom is not meaningful for layout**: an iPhone app stays in the …

How to install
mdr add alexey1312/iphone-duo-agent-skill/iphone-duo-adaptivity-audit@sha256:10da8ff555ac90b7The line at the top of this page pins the label git:20261030.98cdb7c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
