# properties

An array containing the properties of the receiver.

## Declaration

```swift
var properties: [NSPropertyDescription] { get set }
```

## Discussion

Discussion The elements in the array are instances of NSAttributeDescription, NSRelationshipDescription, and/or NSFetchedPropertyDescription. Special Considerations Setting the properties raises an exception if the receiver’s model has been used by an object graph manager.
