# Push

Set up push notifications.

## APNS certificate

To use **push notifications** with this SDK, you have to provide **APNS Key** and upload it to our Sinch Panel.

## Xcode Capabilities

Make sure you’ve enabled the `Remove notifications` capability in `Background Modes` in your target configuration in the tab `Signing & Capabilities` and the `Push Notifications` tab.

## Methods in AppDelegate.swift or AppDelegate.m:


```swift
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

SinchChatSDK.shared.push.sendDeviceToken(deviceToken)

}
```

Make sure you’ve added `UNUserNotificationCenterDelegate` to AppDelegate definition or to you own class.


```swift
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {



if SinchChatSDK.shared.push.handleNotificationResponse(response) {

// this is our notification and it is handled by SinchChatSDK

}



completionHandler()

}
```


```swift
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {



if let presentationOptions = SinchChatSDK.shared.push.handleWillPresentNotification(notification) {

completionHandler(presentationOptions)

return

}

completionHandler([])

}
```
