# suspend()

Temporarily suspends a task.

```
func suspend()
```

## Discussion

A task, while suspended, produces no network traffic and isn’t subject to timeouts. Call [`resume()`](/documentation/Foundation/URLSessionTask/resume()) to resume data transfer.

## See Also

[`cancel(byProducingResumeData:)`](/documentation/Foundation/URLSessionDownloadTask/cancel(byProducingResumeData:))

Cancels a download and calls a callback with resume data for later use.
