# accessibilityPerformIncrement()

Increments the stepper’s value.

```
func accessibilityPerformIncrement() -> Bool
```

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if the action was successfully triggered; otherwise, <doc://com.apple.documentation/documentation/Swift/false>. This method does not indicate the success or failure of the action, just the fact that the action was successfully triggered.

## Discussion

This method must post an [`valueChanged`](/documentation/AppKit/NSAccessibility-swift.struct/Notification/valueChanged) notification after changing the stepper’s value.
