Push Notification Setup.md

Adding the Kommunicate plugin:

Add the Kommunicate iOS SDK in your app using the following guide: https://docs.kommunicate.io/docs/ios-installation

Setting set up FCM:

1. Add the Firebase Core and FirebaseMessaging pods in the PodFile and run pod install.
   (https://firebase.google.com/docs/cloud-messaging/ios/client#add-sdks)

2. In the AppDelegate.swift file, set up the methods to configure Firebase and set the Firebase Messaging delegate. This includes methods to get the FCM token and refresh it whenever it changes.
   (https://firebase.google.com/docs/cloud-messaging/ios/client#set-the-messaging-delegate)

Setting up Kommunicate for notifications:

1. In AppDelegate.swift file’s didReceiveRegistrationToken(), pass the FCM registration token to Kommunicate server.

(https://docs.kommunicate.io/docs/ios-pushnotification#send-device-token-to-kommunicate-server)

Disabling Method Swizzling

1. To disable method swizzling: add the flag FirebaseAppDelegateProxyEnabled in the app’s Info.plist file and set it to NO (boolean value)

2. For apps with method swizzling disabled, associating the FCM token with the device's APNs token and passing notification-received events to Analytics should be done manually.

Receiving notifications:

To handle the app launch, when the user clicks on a notification, check if the notification received is a Kommunicate notification.

1. In the userNotificationCenter(_:didReceive:withCompletionHandler:), pass the response dictionary to Kommunicate Notification Service’s isKommunicateNotification().
   (https://docs.kommunicate.io/docs/ios-pushnotification#handle-app-launch-on-notification-click)

2. If true, it can be then passed to process the notification, using the processPushNotification(dict) method.

3. If false, the notification can be passed onto FCM’s appDidReceiveMessage(_:) method.
