# CWEventDelegate

The interface a Wi-Fi client object uses to notify its delegate about Wi-Fi events.

## Declaration

```swift
protocol CWEventDelegate
```

## Overview

Overview An object that adopts the CWEventDelegate protocol and that is assigned as the delegate of a CWWiFiClient object receives notifications of changes on a Wi-Fi interface. Use the startMonitoringEvent(with:) method to indicate to the client the event types for which you want to receive notifications. Use the stopMonitoringEvent(with:) method to stop receiving a particular notification type, or the stopMonitoringAllEvents() method to stop receiving all notifications.
