# storeIdentifier(forConfigurationNamed:)

Returns the on-disk store identifier for the given configuration name.

## Declaration

```swift
func storeIdentifier(forConfigurationNamed name: String) -> String?
```

## Parameters

- `name`: The name value from the ModelConfiguration used to create the store.

## Return Value

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

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".
