# AppMigrationKit
One-time cross-platform data transfer for app resources. Enables apps to
export data from one platform (e.g., Android) and import it on iOS during
device setup or onboarding. iOS 26+ / iPadOS 26+ / Swift 6.3.
> **Beta-sensitive.** AppMigrationKit is new in iOS 26 and may change before GM.
> Re-check current Apple documentation before relying on specific API details.
AppMigrationKit uses an app extension model. The system orchestrates the
transfer between devices. The app provides an extension conforming to export
and import protocols, and the system calls that extension at the appropriate
time. The app itself never manages the network connection between devices.

## Architecture Overview
AppMigrationKit operates through three layers:
1. **App extension** -- An `AppMigrationExtension` conforming type that the
system invokes during migration. It handles data export and import.
2. **System orchestration** -- The OS manages the device-to-device session,
transport, and scheduling. The exte
