# FoveatedStreamingProviderMessageChannel

A message channel between the host app and a streaming provider extension.

## Declaration

```swift
@MainActor final class FoveatedStreamingProviderMessageChannel
```

## Overview

Overview Message channels are created by the framework when the host app opens a channel and delivered to the extension via openMessageChannel(_:). Provider extensions do not construct values of this type directly. A channel unifies both directions of message flow: Messages the host app sends to the extension arrive on receivedMessages. Data the extension receives from the streaming endpoint is delivered to the host app via send(_:).
