# subentities

An array containing the sub-entities of the receiver.

## Declaration

```swift
var subentities: [NSEntityDescription] { get set }
```

## Discussion

Discussion The sub-entities are instances of NSEntityDescription. Special Considerations Setting the sub-entities raises an exception if the receiver’s model has been used by an object graph manager.
