# fetchAllLongLivedOperationIDs(completionHandler:)

Fetches the IDs of any long-lived operations that are running.

```
@preconcurrency func fetchAllLongLivedOperationIDs(completionHandler: @escaping @Sendable ([CKOperation.ID]?, (any Error)?) -> Void)
```

## Parameters

`completionHandler`

The closure to execute with the fetch results.

## Discussion

The closure doesn’t return a value and takes the following parameters:

- The IDs of all of the long-lived operations that are running.
- An error if a problem occurs, or `nil` if CloudKit successfully retrieves the IDs.

A long-lived operation is one that continues to run after the user closes your app. When a long-lived operation completes, or your app or the system cancels it, it’s no longer active and CloudKit doesn’t include its ID in `outstandingOperationsByIDs`. An operation is complete when the system calls its completion handler.

Use the [`longLivedOperation(for:)`](/documentation/CloudKit/CKContainer/longLivedOperation(for:)) method to fetch the operation for a specific ID.
