# NSWritingToolsCoordinator.TextUpdateReason

Constants that specify the reason you updated your view’s content outside of the Writing Tools workflow.

## Declaration

```swift
enum TextUpdateReason
```

## Overview

Overview If you modify your view’s text storage while Writing Tools is active, report those changes to your NSWritingToolsCoordinator object so it can track them correctly. Call the updateRange(_:with:reason:forContextWithIdentifier:) method to report changes that occur inside one of your context objects. Call the updateForReflowedTextInContextWithIdentifier(_:) method for changes that affect the layout of your text, such as text insertions before a context object or changes to your view’s frame rectangle.
