Widgets, Live Activities, StandBy and Controls for apps on iPhone Duo, Apple's foldable. Use it when you build or check a widget extension, a Live Activity, a Dynamic Island presentation, a StandBy layout or a Control Center or Lock Screen control, and the app runs on iPhone Duo. Covers the redesigned Dynamic Island in the side column of the outer and inner display, which grows down that column as Live Activities arrive and takes room from the app's own vertical bars…
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
# duo-system-surfaces The system draws your widgets, Live Activities and controls, not your app. On iPhone Duo it draws them in new places: a Dynamic Island in the side column of both displays, two Home Screen pages with Today View, StandBy on either display. You can't lay these places out. Your job is to give each presentation content that still reads when the system makes it narrower, taller or bigger, and to check on a device what the simulator can't show. Load neighbours when the task needs them: `duo-navigation` (your app's bars, which share the side column with the island), `duo-continuity` (opening the right screen from a tap), `duo-swiftui-27` (`visibilityPriority` and the other iOS 27 toolbar APIs). Labels: *measured* means we ran it on the iPhone Duo simulator (iOS 27.1, 20 October 2026). *Unverified* means we could not confirm it. *Not published* means Apple has said nothing about it as of 20 October 2026. Everything else links to Apple. Runs: [references/evidence.md](references/evidence.md).

How to install
mdr add kimeur/duology/duo-system-surfaces@sha256:f5397e187e4a6590The line at the top of this page pins the label git:20261020.b09cda5, 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.
