# expectedSendSize

The estimated size of traffic to upload to CloudKit.

## Declaration

```swift
var expectedSendSize: CKOperationGroup.TransferSize { get set }
```

## Discussion

Discussion This property informs the system about the amount of data your app can transfer. An order-of-magnitude estimate is better than no estimate, and accuracy helps performance. The system checks this value when it schedules discretionary network requests.
