# CWWiFiClient

A wrapper around the entire Wi-Fi subsystem that you use to access interfaces and set up event notifications.

```
class CWWiFiClient
```

## Overview

Wi-Fi client objects are heavy. Therefore, it’s more efficient to use a single, long-running client instance, rather than creating several short-lived instances. For convenience, you can use the singleton instance returned by the [`shared()`](/documentation/CoreWLAN/CWWiFiClient/shared()) class method.

Instead of instantiating [`CWInterface`](/documentation/CoreWLAN/CWInterface) objects directly, use the ones provided by the instance methods of this class. For example, the [`interface()`](/documentation/CoreWLAN/CWWiFiClient/interface()) method returns the default Wi-Fi interface.

## Topics

### Getting the Shared Instance

[`shared()`](/documentation/CoreWLAN/CWWiFiClient/shared())

The shared Wi-Fi client object.

### Initializing a Wi-Fi Client

[`init()`](/documentation/CoreWLAN/CWWiFiClient/init())

Initializes a Wi-Fi client object.

### Setting a Delegate

[`delegate`](/documentation/CoreWLAN/CWWiFiClient/delegate)

An object that provides Wi-Fi event handling.

### Getting Interfaces

[`interface()`](/documentation/CoreWLAN/CWWiFiClient/interface())

Returns the default Wi-Fi interface.

[`interface(withName:)`](/documentation/CoreWLAN/CWWiFiClient/interface(withName:))

Returns the Wi-Fi interface with the given name.

[`interfaces()`](/documentation/CoreWLAN/CWWiFiClient/interfaces())

Returns all available Wi-Fi interfaces.

[`interfaceNames()`](/documentation/CoreWLAN/CWWiFiClient/interfaceNames()-swift.type.method)

Returns the list of the names of available Wi-Fi interfaces.

### Monitoring Events

[`startMonitoringEvent(with:)`](/documentation/CoreWLAN/CWWiFiClient/startMonitoringEvent(with:))

Register for specific Wi-Fi event notifications.

[`stopMonitoringAllEvents()`](/documentation/CoreWLAN/CWWiFiClient/stopMonitoringAllEvents())

Unregister for all Wi-Fi event notifications.

[`stopMonitoringEvent(with:)`](/documentation/CoreWLAN/CWWiFiClient/stopMonitoringEvent(with:))

Unregister for specific Wi-Fi event notifications.

### Instance Methods

[`interfaceNames()`](/documentation/CoreWLAN/CWWiFiClient/interfaceNames()-swift.method)
