# storeIdentifier(forConfigurationNamed:) Returns the on-disk store identifier for the given configuration name. ``` func storeIdentifier(forConfigurationNamed name: String) -> String? ``` ## Parameters `name` The `name` value from the `ModelConfiguration` used to create the store. ## Return Value The store identifier string, or `nil` if no store is associated with `name` or if `invalidate()` has been called on this container. ## Discussion Store identifiers are stable strings derived from the backing file path or the store’s own initialization — they are *not* the configuration name. Use this function when you have the name you passed to `ModelConfiguration` and need the corresponding identifier to filter a `HistoryDescriptor`, interpret `PersistentIdentifier.storeIdentifier`, or route to a specific store. If no `ModelConfiguration` was given an explicit name at initialization time, the default name is `"default"`. --- Copyright © 2026 Apple Inc.
