# automaticRearrangementKeyPaths

An array of key paths that trigger automatic content sorting or filtering

## Declaration

```swift

```

## Discussion

Discussion Subclasses can override this property to customize the default behavior of the sort descriptors and filtering predicates, for example, if additional arrangement criteria are used in a custom implementation of arrangedObjects.
