# willProcessEditingNotification

A notification that posts before a text storage begins processing edits.

## Declaration

```swift
class let willProcessEditingNotification: NSNotification.Name
```

## Discussion

Discussion The framework posts this notification before a text storage begins processing edits in processEditing(). Observers other than the delegate shouldn’t make further changes to the text storage. The notification object is the text storage object that’s about to process the edits. This notification doesn’t contain a userInfo dictionary.
