Instance Property


Estimated size of traffic being uploaded to CloudKit.


var expectedSendSize: CKOperationGroup.TransferSize { get set }


This property informs the system how much data your app may. An order-of-magnitude estimate is better than no estimate, and accuracy will help with performance. The system checks this value when scheduling discretionary network requests.
