# PTChannelManager

An object that represents a push-to-talk channel manager.

## Declaration

```swift
class PTChannelManager
```

## Mentioned in

Creating a Push to Talk app

## Overview

Overview You must create a channel manager upon launching your app, otherwise the system tears down channels and their ability to receive push notifications. By providing a PTChannelRestorationDelegate, an app can rejoin or leave a previously active channel the system knows about. Once the channel resoration process completes, the system provides a PTChannelManager instance. // Create a channel manager instance.     channelManager = try await PTChannelManager.channelManager(delegate: self,                                                            restorationDelegate: self) Multiple calls to channelManager(delegate:restorationDelegate:completionHandler:) result in the system returning the same shared instance, so store the channel manager in an instance variable.
