Migrates a Capacitor iOS app or plugin from the AppDelegate lifecycle to the UIScene lifecycle introduced in Capacitor 8.5 and required by Xcode 27. Audits first (custom AppDelegate URL/lifecycle code, CAPBridgeViewController subclasses, existing SceneDelegate.swift, Info.plist UIApplicationSceneManifest, project.pbxproj registration, plugin lifecycle observers, tmpWindow/TmpViewController), reports, then merges surgically or hands template-shaped projects to `npx cap migrate`.

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
# Capacitor UIScene Migration (8.4 -> 8.5) Capacitor 8.5 moved the iOS template to the UIScene lifecycle because Xcode 27 requires it. It shipped as a breaking minor, iOS only. The 8.5 core still runs the AppDelegate path, so bumping the dependency alone does not break an app; the app project must adopt scenes before it can build with Xcode 27 (and before Capacitor 9). Canonical source: https://capacitorjs.com/docs/updating/8-5 ## When to Use TRIGGER when: - App is on `@capacitor/ios` 8.0-8.4, or on 8.5 without `UIApplicationSceneManifest` in `Info.plist` - Xcode 27 build or runtime warning "CLIENT OF UIKIT REQUIRES UPDATE: This process does not adopt UIScene lifecycle" - `npx cap migrate` printed `UIScene migration: project is in a partial state ... Skipping automated migration` - After adding a scene manifest: custom URL scheme, universal link, `appUrlOpen`, or AppDelegate `applicationDidBecomeActive` code stopped running - Build error on `tmpWindow` or `TmpViewController` after updating to 8.5 - A plugin author asks whether their iOS code survives the scene lifecycle - Preparing a Capacitor 8 -> 9 upgrade from 8.4 or earlier Do not use: …

How to install
mdr add cap-go/capgo-skills/capacitor-uiscene-migration@sha256:294f7655b5a7996cThe line at the top of this page pins the label git:20261011.86834d4, 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.
