Solution
Perform the following steps:
-
Check for app_group_id in your project’s main target for each configuration:
You can add the same app_group_id or different ones across configurations.
info Information
If your configurations use different Bundle Identifiers but share the same app_group_id, issues may arise. Specifically, if two apps with different Bundle Identifiers but the same app_group_id are installed on the same device, the Notification Service Extension may fail.
To avoid this, you can use the same app_group_id across multiple configurations, but be aware that you won't be able to test all apps simultaneously on a single device.
- Check for app_group_id during SDK initialization:
- If the SDK is initialized using info.plist, the APP_GROUP_ID key must be there inside the MoEngage key in your info.plist file.
- If the SDK is initialized using sdkConfig, the APP_GROUP_ID must be in the sdkConfig variable inside the AppDelegate file.
app_group_id in info.plist:
app_group_id in sdkConfig variable:
var sdkConfig = MOSDKConfig.init(appID: "XXXXXXXXXXXXXXXX") sdkConfig.moeDataCenter = DATA_CENTER_0X sdkConfig.appGroupID = "group.com.XXXXXXXXXXXXXXXX" //if SDK initialized without sdkConfig in AppDelegate file MoEngage.setAppGroupID("group.com.moengage.MIPL567.demo")
MOSDKConfig* sdkConfig = [[MOSDKConfig alloc] initWithAppID: @"XXXXXXXXXXXXXXXX"]; sdkConfig.moeDataCenter = DATA_CENTER_0X; sdkConfig.appGroupID = @"group.com.XXXXXXXXXXXXXXXX"; //if SDK initialized without sdkConfig in AppDelegate file [MoEngage setAppGroupID: @"group.com.XXXXXXXXXXXXXXXX"];
- Check for a Notification Service Extension Target:
- Enable Push Notifications: In the extension target's Signing & Capabilities section, make sure to enable Push Notifications and add the AppGroupId.
- Align the Minimum Deployment iOS Version: Ensure that the minimum deployment iOS version of the Notification Service Extension matches the iOS version of the main app.
- Integrate the MORichNotification Framework into the Notification Service Extension target.
target 'MoEngageDemo' do use_frameworks! pod 'MoEngage-iOS-SDK' end target 'MoEngageNotificationService' do use_frameworks! #use use_frameworks only if included in main target as in above scenario pod 'MORichNotification' end
- NotificationService.swift file looks like this:
import UserNotifications import MORichNotification class NotificationService: UNNotificationServiceExtension { var contentHandler: ((UNNotificationContent) - Void)? var bestAttemptContent: UNMutableNotificationContent? override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) - Void) { MORichNotification.setAppGroupID("group.com.XXXXXXXXXXXXXXXX") self.contentHandler = contentHandler bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent) MORichNotification.handle(request, withContentHandler: contentHandler) } override func serviceExtensionTimeWillExpire() { // Called just before the extension will be terminated by the system. // Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used. if let contentHandler = contentHandler, let bestAttemptContent = bestAttemptContent { contentHandler(bestAttemptContent) } } }
- Check Build Phases for the Main App Target: In the Build Phases section of the main app target, locate the Embed App Extensions / Embed Foundation Extensions section. Ensure that the Copy only when installing option is unchecked.
- Ensure Consistent appGroupId Across Configurations: Verify that the appGroupId is consistent across all schemes and configurations (e.g. Debug/Release/QA/UAT) in the project.
- Align Build Configuration: When running or archiving the project, ensure that the Build Configuration for the Main Target and Notification Service Extension Target points to the same scheme/configuration.
