# CKSyncEngine.SendChangesContext

The context of an attempt to send changes to the server.

## Declaration

```swift
struct SendChangesContext
```

## Overview

Overview 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 sendChanges(_:) method. This type 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.
