Declaration
@interface CKSyncEngineSendChangesContext : NSObjectOverview
A sync engine has two ways to send changes to iCloud — periodically, in cooperation with the system scheduler, and manually, whenever your app invokes the sendChangesWithCompletionHandler: method. This object provides information about a single attempt to send changes that includes both the reason for the attempt and any additional options in use by the attempt.
