• Start with a basic project with CleverTap set up using the steps mentioned here
  • Get the SDK
  • Update the Info.plist with id and token
• Integrate basic CT

CleverTap.setDebugLevel(CleverTapLogLevel.debug.rawValue)
CleverTap.autoIntegrate();

• Enable Push notifications (basic baground and killed state)
  • Register for push - ref
  • Ensure that Push notifications and background mode are added to the capabilities
• Add the notification service extension
  • By just sending a push now, with mutable-content flag checked, the breakpoint should hit the receive function of the extension
• Add CTNotificationService in the pod file for the extension - ref
  • pod 'CTNotificationService' and run pod install
  • Ensure that CT token, id are in Info.plist of the extension
  • Extend NotificationService from CTNotificationServiceExtension
  • Update the didReceive function as follows

self.contentHandler = contentHandler
bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)

CleverTap.setDebugLevel(3)
CleverTap.sharedInstance()?.recordNotificationViewedEvent(withData: request.content.userInfo)
super.didReceive(request, withContentHandler: contentHandler)

Leave the info.plist as it - Keep $(PRODUCT_MODULE_NAME).NotificationService as value for NSExtensionPrincipalClass. Changing this value to CTNotificationServiceExtension stops the debugger from hitting the didReceive function of NotificationService class [This needs to be checked further]

At this point, the images should start working if

• From CleverTap, we're setting the Advanced options -
  • url for the image (Rich media turned on)
  • mutable-content checked

Making Push impressions work

• Update the Podfile so now our service extension also depends on CleverTap SDK

target 'NotificationServiceExtention'  do
	pod 'CTNotificationService'
	pod "CleverTap-iOS-SDK"
end

• Update the NotificationService class to raise an event for CleverTap to record notification viewed (Push impression in the backend)

CleverTap.setDebugLevel(3)
CleverTap.sharedInstance()?.recordNotificationViewedEvent(withData: request.content.userInfo)

For push impressions to go into the correct profile

• Add "App groups" capability to main target as well as notification service target
  • From your App developer account, go to Certificates, Identifiers & Profiles -> Identifiers. Find your app & the app extension identifiers.
  • Select your app identifier, click on the App Groups and Configure the identifier to be part of an app group.
  • This step will require you to generate a new provisioning profile for the app identifier. Update the profile in the Xcode to sign your app.
  • Once the app groups are set, from your login - set the identity to the userdefaults

if let groupUserDefaults = UserDefaults(suiteName: "group.com.sunny.ctios") {
       groupUserDefaults.set(identity, forKey: "identity")
}

And in your didReceive function (NotificationService class), read that value and login user -

if let groupUserDefaults = UserDefaults(suiteName: "group.com.sunny.ctios") {
      if let identity = (groupUserDefaults.object(forKey: "Identity")) as? String {
      let profile: Dictionary<String, Any> = ["Identity": identity]
       print("[Clevertap] Identity" + " logged in to the service extension")
       CleverTap.sharedInstance()?.onUserLogin(profile)
   }
}

Now that the user is logged in, call the notificationViewed event -

CleverTap.sharedInstance()?.recordNotificationViewedEvent(withData: request.content.userInfo)

Also, make sure to call super.didReceive so that the images are rendered correctly.

Few things to keep in mind -

• Payload needs to have "mutable-content": 1
• iOS version of Service extension should be less than equal to the iOS version of the targeted device.
• Restart of the device may be required
• Apple supports Service extension from iOS 10
