# performFeedback(_:performanceTime:)

Performs the haptic feedback described by one or more alignment feedback tokens.

```
func performFeedback(_ alignmentFeedbackTokens: [any NSAlignmentFeedbackToken], performanceTime: NSHapticFeedbackManager.PerformanceTime)
```

## Parameters

`alignmentFeedbackTokens`

One or more feedback tokens prepared for specific alignment locations by calling [`alignmentFeedbackTokenForMovement(in:previousPoint:alignedPoint:defaultPoint:)`](/documentation/AppKit/NSAlignmentFeedbackFilter/alignmentFeedbackTokenForMovement(in:previousPoint:alignedPoint:defaultPoint:)), [`alignmentFeedbackTokenForHorizontalMovement(in:previousX:alignedX:defaultX:)`](/documentation/AppKit/NSAlignmentFeedbackFilter/alignmentFeedbackTokenForHorizontalMovement(in:previousX:alignedX:defaultX:)), or [`alignmentFeedbackTokenForVerticalMovement(in:previousY:alignedY:defaultY:)`](/documentation/AppKit/NSAlignmentFeedbackFilter/alignmentFeedbackTokenForVerticalMovement(in:previousY:alignedY:defaultY:)). Typically, no more than one feedback token per dimension (horizontal/vertical) should be provided.

`performanceTime`

The time, of type `NSHapticFeedbackPerformanceTime`, when the feedback should be provided to the user.

## Discussion

Call this method to initiate haptic feedback to the user. Pass it one or more alignment feedback tokens of type `NSAlignmentFeedbackToken` and a time to execute of type `NSHapticFeedbackPerformanceTime`. Call this method immediately before moving the object to its new aligned position.
