+# Migrating a Mindbox Flutter SDK integration to UISceneDelegate
+
+Starting with Flutter 3.35 the iOS engine ships `FlutterSceneDelegate`, and
+since Flutter 3.41 `UISceneDelegate`-based lifecycle is the recommended path
+for new iOS Flutter apps. The official Flutter migration guide is the
+authoritative source for everything not Mindbox-specific:
+
+- [Flutter UISceneDelegate migration guide][flutter-uiscene]
+
+This document only describes the Mindbox-side glue you need on top of the
+Flutter migration: where to forward `.launchScene` and `.universalLink`
+events, and what stays in your `AppDelegate`. It does **not** repeat the
+Flutter-side steps already covered in the link above (`Info.plist` scene
+manifest, `FlutterImplicitEngineDelegate` boilerplate, etc.) — follow them
+there and use this page for the Mindbox-specific bits.
+
+If your `Info.plist` does **not** contain `UIApplicationSceneManifest`,
+nothing changes for you. The Mindbox iOS SDK pod itself does not depend on
+any scene-specific Flutter API, so it keeps building and running on every
+Flutter version we supported before. You can update to the latest Mindbox
+SDK without touching your code.
+
+## Why this matters for Mindbox integrators
+
+Under `UIApplicationSceneManifest` two `AppDelegate` callbacks Mindbox
+previously relied on stop working as before:
+
+- `application(_:didFinishLaunchingWithOptions:)` still fires, but
+  `launchOptions` is `nil`, so `Mindbox.shared.track(.launch(launchOptions))`
+  tracks nothing useful.
+- `application(_:continue:restorationHandler:)` is never invoked — universal
+  links arrive in `scene(_:continue:)` instead.
+
+To keep Mindbox receiving launch and universal-link events you need to
+forward them from your scene delegate.
+
+## Prerequisites
+
+- **Flutter ≥ 3.41** — required for `FlutterImplicitEngineDelegate` on the
+  app side (see the Flutter guide above).
+- iOS deployment target ≥ 13.0.
+
+## What to add in your scene delegate
+
+Copy
+[`example/flutter_example/ios/Runner/SceneDelegate.swift`](https://github.com/mindbox-cloud/flutter-sdk/blob/develop/example/flutter_example/ios/Runner/SceneDelegate.swift)
+into your `Runner` target. The two relevant calls:
+
+```swift
+override func scene(
+    _ scene: UIScene,
+    willConnectTo session: UISceneSession,
+    options connectionOptions: UIScene.ConnectionOptions
+) {
+    Mindbox.shared.track(.launchScene(connectionOptions))
+    super.scene(scene, willConnectTo: session, options: connectionOptions)
+}
+
+override func scene(
+    _ scene: UIScene,
+    continue userActivity: NSUserActivity
+) {
+    Mindbox.shared.track(.universalLink(userActivity))
+    super.scene(scene, continue: userActivity)
+}
+```
+
+That replaces, respectively, `Mindbox.shared.track(.launch(launchOptions))`
+in `application(_:didFinishLaunchingWithOptions:)` and
+`Mindbox.shared.track(.universalLink(userActivity))` in
+`application(_:continue:restorationHandler:)`.
+
+You may keep both AppDelegate-side and SceneDelegate-side calls — in scene
+mode the AppDelegate-side `.launch(nil)` and `application(_:continue:)` are
+inert (`launchOptions == nil`, the method is not invoked), so the two paths
+do not produce duplicate events.
+
+## What stays unchanged in your AppDelegate
+
+Even after the scene migration you keep all of the following on your
+`AppDelegate` (typically a subclass of `MindboxFlutterAppDelegate`):
+
+- `Mindbox.shared.apnsTokenUpdate(deviceToken:)` in
+  `application(_:didRegisterForRemoteNotificationsWithDeviceToken:)`.
+- `Mindbox.shared.pushClicked(response:)` and
+  `Mindbox.shared.track(.push(response))` in your
+  `UNUserNotificationCenterDelegate` methods.
+- `Mindbox.shared.registerBGTasks()`.
+- Notification permission requests.
+
+`UNUserNotificationCenterDelegate` is a process-global API and is not
+affected by scene mode, so push handling needs no changes.
+
+`MindboxFlutterAppDelegate` itself is scene-safe — it does not touch
+`window` or `rootViewController` — and continues to work as a base class
+unchanged.
+
+## Notification Service / Content Extensions
+
+`MindboxNotificationServiceExtension` and
+`MindboxNotificationContentExtension` are extension processes and have
+nothing to do with the host app's scene flow. They need no changes.
+
+## Reference implementation
+
+[`example/flutter_example/ios/Runner`](https://github.com/mindbox-cloud/flutter-sdk/tree/develop/example/flutter_example/ios/Runner)
+is fully migrated and serves as a working reference for both the
+Flutter-side and Mindbox-side parts of the migration.
