# init(for:migrationPlan:configurations:) Creates a model container using the specified schema, migration plan, and zero or more configurations. ``` convenience init(for givenSchema: Schema, migrationPlan: (any SchemaMigrationPlan.Type)? = nil, configurations: ModelConfiguration...) throws ``` ## Parameters `givenSchema` A schema that maps your app’s model classes to the associated data in the app’s persistent storage. For more information, see [`Schema`](/documentation/SwiftData/Schema). `migrationPlan` A plan that describes the evolution of your app’s schema and how the container migrates between specific versions. For more information, see [`SchemaMigrationPlan`](/documentation/SwiftData/SchemaMigrationPlan). `configurations` A list of configurations that describe how the container manages the persisted data for specific groups of models. For more information, see [`ModelConfiguration`](/documentation/SwiftData/ModelConfiguration). ## Discussion> Important: A container must have at least one configuration. If you don’t > specify any, the framework creates an instance of ``doc://com.apple.SwiftData/documentation/SwiftData/ModelConfiguration`` for > you by combining your app’s entitlements with the type’s default values. --- Copyright © 2026 Apple Inc.
