# pausingHandler

The block to invoke when pausing progress.

## Declaration

```swift
var pausingHandler: (@Sendable () -> Void)? { get set }
```

## Discussion

Discussion If the receiver is a suboperation of another progress object, the system invokes the pausingHandler block when pausing the containing progress object. Special Considerations You’re responsible for pausing any work for the progress object. You can invoke the pausing handler on any queue. If you must do work on a specific queue, dispatch to that queue from within the pausing handler block.
