# CXSetGroupCallAction

An encapsulation of the act of grouping or ungrouping calls.

```
class CXSetGroupCallAction
```

## Overview

[`CXSetGroupCallAction`](/documentation/CallKit/CXSetGroupCallAction) is a concrete subclass of [`CXCallAction`](/documentation/CallKit/CXCallAction). When the user or the system groups a call with another call, the provider sends [`provider(_:perform:)`](/documentation/CallKit/CXProviderDelegate/provider(_:perform:)-9masw) to its delegate. The provider’s delegate calls the [`fulfill()`](/documentation/CallKit/CXAction/fulfill()) method to indicate that the action was successfully performed. A group call allows more than two recipients to simultaneously communicate with one another.

## Topics

[`init(call:callUUIDToGroupWith:)`](/documentation/CallKit/CXSetGroupCallAction/init(call:callUUIDToGroupWith:))

[`init(coder:)`](/documentation/CallKit/CXSetGroupCallAction/init(coder:))

Creates a new action to group calls with data in an unarchiver.

### Accessing Action Attributes

[`callUUIDToGroupWith`](/documentation/CallKit/CXSetGroupCallAction/callUUIDToGroupWith)
