Connection Status

Monitor real-time WebSocket connection status and respond to connectivity changes using the CometChat iOS SDK.

AI Integration Quick Reference

// Get current status: "connecting" | "connected" | "disconnected"
let status = CometChat.getConnectionStatus?.value

// Listen for connection changes
// Conform to CometChatConnectionDelegate
CometChat.addConnectionListener("LISTENER_ID", self as CometChatConnectionDelegate)

func connecting() { print("Connecting...") }
func connected() { print("Connected") }
func disconnected() { print("Disconnected") }

// Cleanup
CometChat.removeConnectionListener("LISTENER_ID")

The CometChat SDK maintains a WebSocket connection to CometChat servers for real-time events. You can check the current connection state and listen for changes, useful for showing connectivity indicators in your UI or queuing operations while offline.

When the connection drops, the SDK automatically attempts to reconnect, cycling through disconnected -> connecting -> connected.

Connection States

Value	Callback	Description
"connected"	connected()	SDK has an active connection to CometChat servers
"connecting"	connecting()	SDK is attempting to establish or re-establish a connection
"disconnected"	disconnected()	SDK is disconnected due to network issues or other errors

Get Current Status

Use getConnectionStatus to check the current connection state at any time:

Swift

var connectionStatus = CometChat.getConnectionStatus?.value

Listen for Connection Changes

Register a CometChatConnectionDelegate to receive real-time connection state updates. We recommend adding this in your AppDelegate and in your app’s first view controller after login.

Swift

extension AppDelegate: CometChatConnectionDelegate {

    func connecting() {
        print("connecting")
    }
    
    func connected() {
        print("connected")  
    }
    
    func disconnected() {
        print("disconnected")
    }
}

Objective C

@interface ViewController ()<CometChatConnectionDelegate>
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [CometChat connectiondelegate:self];
}

- (void)connecting {
    NSLog(@"Connecting");
}

- (void)connected {
    NSLog(@"Connected");
}

- (void)disconnected {
    NSLog(@"Disconnected");
}

Always remove connection listeners when they’re no longer needed. Failing to remove listeners can cause memory leaks and duplicate event handling.
