What it does
Transfer app data to or from other platforms using AppMigrationKit. Use when implementing system-orchestrated one-time migration between iOS and Android or another platform, building an AppMigrationExtension, packaging transportable resources with ResourcesArchiver, importing resources on the destination device, reporting import progress, handling migration errors and app group cleanup, checking MigrationStatus, or testing migration code with AppMigrationTester.
AppMigrationKit
One-time cross-platform data transfer for app resources. Enables apps to export data to or import data from another platform (for example, Android) during device setup or onboarding. AppMigrationKit APIs are iOS 26.0+ / iPadOS 26.0+; the data-container entitlement is iOS 26.1+ / iPadOS 26.1+ / Mac Catalyst 26.1+. 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:
- App extension -- An
AppMigrationExtensionconforming type that the system invokes during migration. It handles data export and import. - System orchestration -- The OS manages the device-to-device session, transport, and scheduling. The extension does not control when it runs.
- Containing app -- After migration completes, the app checks
MigrationStatus.importStatuson first launch to determine whether migration occurred and whether it succeeded.
