appmigrationkit

What problem does it solve?

Enables one-time, reliable transfer of an app's user data and resources from other platforms (for example Android) into iOS during device setup or onboarding without the containing app managing the network transport.

Core Features & Use Cases

• App extension model driven by an AppMigrationExtension that runs during system-orchestrated migration sessions and accesses the containing app's data container.
• Exporting files incrementally via ResourcesArchiver with size estimates, versioning, and optional compression to avoid timeouts and disk bloat.
• Importing resources with sourceVersion handling, clearing app group containers before writes, progress reporting via Progress, and MigrationStatus checks on first launch.
• Testing patterns using AppMigrationTester for export/import round trips and unit validation of migration logic.
• Use case: migrate user profile, settings, and media from an Android app to iOS during initial onboarding, showing progress and safely recovering from import errors.

Quick Start

Use AppMigrationKit to export your app's Documents and Application Support directories from the source device and import them into the containing iOS app during onboarding.
