# UIFeedbackGenerator

The abstract superclass for all feedback generators.

## Declaration

```swift
@MainActor class UIFeedbackGenerator
```

## Overview

Overview Don’t subclass or create instances of this class yourself. Instead, instantiate one of the concrete feedback generator subclasses: UIImpactFeedbackGenerator. Use impact feedback to indicate when an impact occurs. For example, you might trigger impact feedback when a user interface object collides with something or snaps into place. UISelectionFeedbackGenerator. Use selection feedback to indicate a change in selection. UINotificationFeedbackGenerator. Use notification feedback to indicate successes, failures, and warnings. UICanvasFeedbackGenerator. Use canvas feedback to indicate when a drawing event occurs, such as an object snapping to a guide or ruler. For more information, read Playing haptic feedback in your app.
