# CKOperationGroup

An explicit association between two or more operations.

## Declaration

```swift
class CKOperationGroup
```

## Overview

Overview In certain situations, you might want to perform several CloudKit operations together. Grouping operations in CloudKit doesn’t ensure atomicity. For example, when building a Calendar app, you group the following actions: Fetch records from CloudKit, which consists of numerous queries that fetch both new records and records with changes. Perform incremental fetches of records in response to a push notification. Update several records when the user saves a calendar event. Associate operation groups with operations by setting their group property. Create a new operation group for each distinct user interaction.
