# Connection Status
> Monitor real-time WebSocket connection status and respond to connectivity changes using the CometChat iOS SDK.
```swift theme={null}
// 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 theme={null}
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 theme={null}
extension AppDelegate: CometChatConnectionDelegate {
func connecting() {
print("connecting")
}
func connected() {
print("connected")
}
func disconnected() {
print("disconnected")
}
}
```
```objc theme={null}
@interface ViewController ()
@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.
