# IOS specific configuration

To enable push notifications for iOS, you need to configure specific capabilities and handle the necessary app delegate code. Let's walk through the steps.

1. **Update iOS pods**

   Run `pod install` in the ios folder of your flutter application to install/update the pod dependencies.
2. **Add capabilities in iOS application**
   1. Open your Flutter project in Xcode.

   2. Inside the **Targets** section, select your app target, and go to **Signing & Capabilities**.

   3. Click on **+ Capability** and add **Push Notifications** and **Background Modes** capabilities.

   4. In Background Modes, select the Remote Notifications option. This is required to receive background push notifications. Learn more about background notifications [here](https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/pushing_background_updates_to_your_app).

3. **Register for push notification in AppDelegate.swift file**

   To handle push notifications in your iOS app, add the following code to `AppDelegate.swift`:
   1. Import the required packages:
   ```swift title="AppDelegate.swift" wordWrap
   import UIKit
   import Flutter
   import fyno_push_ios
   ```
   2. If you are using Firebase Cloud Messaging (FCM), add the Firebase imports:
   ```swift title="AppDelegate.swift" wordWrap
   import FirebaseCore
   import FirebaseMessaging
   ```
   3. Extend `FlutterAppDelegate` and implement the necessary methods:
   ```swift title="AppDelegate.swift" wordWrap
   @UIApplicationMain
   @objc class AppDelegate: FlutterAppDelegate {
       let fynosdk = fyno.app

       override func application(
           _ application: UIApplication,
           didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
       ) -> Bool {
           GeneratedPluginRegistrant.register(with: self)

           UNUserNotificationCenter.current().delegate = fynosdk

           self.fynosdk.registerForRemoteNotifications()

           fynosdk.requestNotificationAuthorization { _ in }

           FirebaseApp.configure() // Optional: Configure Firebase if FCM is used

           return super.application(application, didFinishLaunchingWithOptions: launchOptions)
       }

       override func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
           print("Failed to register for remote notifications: \(error.localizedDescription)")
       }

       override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
           fynosdk.setdeviceToken(deviceToken: deviceToken)

         	Messaging.messaging().apnsToken = deviceToken // Optional: Set APNs token for FCM
       }
   }
   ```
4. **Add a Notification Service Extension**

   To ensure rich push notifications and proper handling of incoming messages, add a `Notification Service Extension` to your iOS project:
   1. In Xcode go to **File** > **New** > **Target**.

   2. Select `Notification Service Extension` from the template list.

   3. Provide a product name, select your development team, choose Swift as the language, and click Finish.

   4. Replace the contents of the generated `NotificationService.swift` file with the following code:
   ```swift title="NotificationService.swift" wordWrap
   import UserNotifications
   import UIKit
   import fyno

   class NotificationService: UNNotificationServiceExtension {
       var contentHandler: ((UNNotificationContent) -> Void)?
       var bestAttemptContent: UNMutableNotificationContent?

       override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
           fyno.app.handleDidReceive(request, withContentHandler: contentHandler)
       }

       override func serviceExtensionTimeWillExpire() {
           if let contentHandler = contentHandler, let bestAttemptContent = bestAttemptContent {
               contentHandler(bestAttemptContent)
           }
       }
   }
   ```
5. **Add Fyno SDK to the Notification Service Extension**

   To allow the Notification Service Extension to use the Fyno SDK, you need to import it:
   1. In Xcode, select your Notification Service Extension target.

   2. Under `Frameworks and Libraries`, click on the **+** button.

   3. Under `Add Other`, click on the `Add Package Dependency`.

   4. Search for `https://github.com/fynoio/ios-sdk` in the text box.

   5. Select and add the `ios-sdk` package.

   6. Ensure the target is set to the Notification Service Extension you created, then click `Add Package`.
