# notifyRulesChanged()

Notify the Filter Data Provider that the filtering rules have changed on disk.

## Declaration

```swift
func notifyRulesChanged()
```

## Discussion

Discussion The Filter Control Provider can call this method to notify the Filter Data Provider that the rules changed. It is only necessary to call this method when the update to the rules was not a direct result of a call to handleNewFlow(_:completionHandler:).
