## Declaration

```swift
var relatedAppEntityIdentifier: EntityIdentifier? { get set }
```

## Discussion

Discussion Use this property to associate a child searchable item such as an attachment or embedded content with its parent IndexedEntity instance. Only an identifier reference is stored. No entity content is embedded in the child item. Setting this property again replaces the previously set identifier.
