Description

Steps to reproduce

1. I followed the steps in the Firebase documentation: [Display Images in Notifications on iOS].

2. I ran the app on the simulator, and everything worked correctly, including receiving notifications with images.

3. However, when I tried to archive the build to create an IPA, the process failed, returning the following error:

   Error:

   Error (Xcode): Multiple commands produce
   '/Users/<user>/Library/Developer/Xcode/DerivedData/Runner-<hash>/Build/Intermediates.noindex/ArchiveIntermediates/<target>/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/GoogleUtilities.framework'
   
   Error (Xcode): Multiple commands produce
   '/Users/<user>/Library/Developer/Xcode/DerivedData/Runner-<hash>/Build/Intermediates.noindex/ArchiveIntermediates/<target>/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/GoogleUtilities_Privacy.bundle'
   
   Encountered error while archiving for device.
   

   I did not modify any code related to the iOS configuration after adding the Notification Service Extension.

Expected results

Successfully archive the iOS build and generate the IPA file without encountering any errors.

Actual results

Archiving fails with the following errors:

Error (Xcode): Multiple commands produce
'/Users/<user>/Library/Developer/Xcode/DerivedData/Runner-<hash>/Build/Intermediates.noindex/ArchiveIntermediates/<target>/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/GoogleUtilities.framework'

'/Users/<user>/Library/Developer/Xcode/DerivedData/Runner-<hash>/Build/Intermediates.noindex/ArchiveIntermediates/<target>/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/GoogleUtilities_Privacy.bundle'

Encountered error while archiving for the device.

Code sample

Code sample

import UserNotifications
import FirebaseMessaging

class NotificationService: UNNotificationServiceExtension {
    var contentHandler: ((UNNotificationContent) -> Void)?
    var bestAttemptContent: UNMutableNotificationContent?
    
    override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
        self.contentHandler = contentHandler
        self.bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)
        guard let bestAttemptContent = bestAttemptContent else {
            contentHandler(request.content)
            return
        }
        // Modify the notification content here...
        Messaging.serviceExtension().populateNotificationContent(bestAttemptContent, 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)
        }
    }
}

Hi @SelaseKay, I tried your solution but still failed.

Also, I have already tried other solutions and followed the steps provided, but unfortunately, it still hasn't worked.

[SelaseKay]

It appears the error message has changed. Can you try this:

cd ios
xcodebuild clean
xcodebuild build

i have the same problem with notification service target

[krokyze]

Fyi. I had the same issue, but it was resolved after I added pod 'GoogleUtilities' to the Podfile for both the Runner target and my notification service extension. However, I’m not entirely sure if that is the right approach.

Hi @Shatha-Naami, could you try @krokyze solution and provide feedback?
