# existingObject(with:)

Returns an existing object from either the context or the persistent store.

## Declaration

```swift
func existingObject(with objectID: NSManagedObjectID) throws -> NSManagedObject
```

## Parameters

- `objectID`: The identifier of the object to retrieve. For more information, see doc://com.apple.coredata/documentation/CoreData/NSManagedObjectID.

## Return Value

Return Value The identified object from either the context or the persistent store.

## Discussion

Discussion If the context recognizes the specified object, the method returns that object. Otherwise, the context fetches and returns a fully realized object from the persistent store; unlike object(with:), this method never returns a fault. If the object doesn’t exist in both the context and the persistent store, the method throws an error.
