 # Enable Push Notifications in your chat app
 
->[!IMPORTANT]
->This Push Notification feature is currently in public preview. Preview APIs and SDKs are provided without a service-level agreement, and aren't recommended for production workloads. Certain features might not be supported or might have constrained capabilities.

 This tutorial will guide you to enable Push Notification in your IOS App by using Azure Communication Chat SDK.  
 Push notifications alert clients of incoming messages in a chat thread in situations where the mobile app isn't running in the foreground. Azure Communication Services supports two versions of push notifications.

 Notice that in the step “Implement Your Extension’s Handler Methods,” Apple provides the sample code to decrypt data and we'll follow the overall structure. However, since we use chat SDK for decryption, we need to replace the part starting from `“// Try to decode the encrypted message data.”` with our customized logic. Refer to the [sample code](https://github.com/Azure-Samples/communication-services-ios-quickstarts/blob/main/add-chat-push-notifications/SwiftPushTestNotificationExtension/NotificationService.swift) to see the related implementation in `NotificationService.swift`.

-Third, `PushNotificationKeyHandler` is required for advanced version. As the SDK user, you could use the default `AppGroupPushNotificationKeyHandler` class provided by chat SDK to generate a key handler. If you don’t use `App Group` as the key storage or would like to customize key handling methods, create your own class which conforms to PushNotificationKeyHandler protocol.

+For PushNotificationKeyStorage, it defines two methods: `onPersistKey(encryptionKey:expiryTime)` and `onRetrieveKeys() -> [String]`.  
 
 The first method is used to persist the encryption key in the storage of user’s IOS device.  Chat SDK will set 45 minutes as the expiry time of the encryption key. If you want Push Notification to be effect for more than 45 minutes, you need to schedule to call `chatClient.startPushNotifications(deviceToken:)` on a comparatively frequent basis (eg. every 15 minutes) so a new encryption key could be registered before the old key expires.
