Firebase push notifications not working for production on iOS

Question

I integrated Firebase Messaging SDK into my iOS project, created a push notification certificate for development and one for production, uploaded both p12 keys to Firebase and I do not receive the notifications, but just for development.

The code for registration is good, and it is the same I used for usual APNS, which worked fine.

The same behaviour happens for 3 applications.

Did someone else encounter this problem? Do you have any solutions or suggestions?

Solution 1

First of all check certificate which you are exporting. Typical mistake is to export private key and not a service. I attached a screenshot. I hope that will save some time for you.

Correct certificate to export

Solution 2

I had the same issue. Apparently there is an error in the Firebase documentation. When you exporting the APN certificate for production from your keychain to the .p12 file you have to select the actual certificate, not the private key.

Make sure you upload to the Firebase console this .p12 file in the Cloud Messaging APN certificate settings.

Swift 4.0

Also make sure you're using:

Messaging.messaging().setAPNSToken(deviceToken as Data, type: .prod)

inside:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

    #if DEVELOPMENT
        //Develop
        Messaging.messaging().setAPNSToken(deviceToken as Data, type: .sandbox)
    #else
        //Production
        Messaging.messaging().setAPNSToken(deviceToken as Data, type: .prod)
    #endif

}

Solution 3

For me these steps resolved the same issue on production:

1. On Apple Developer portal go to Keys - > Add key

2. Download your key, copy Key ID parameter

3. Open Firebase Console - > Project settings -> Cloud messaging
4. Upload your .p8 Key which you downloaded (step 2) here:
5. On new window paste Key ID parameter and your App ID prefix as required

What do you mean about select the actual certificate, not the private key? Thanks in advance

@FlavioKrugerBittencourt I think this refers to the screen in KeyChainAccess program on OSX. When you select the certificate you have the option to drill down into details and see a key as a sub-item of the certificate. Instead of exporting the key, export the top-level certificate.

You've got to be kidding me, once again stackoverflow comes to the rescue. P.S. Firebase still hasn't changed the docs.

Yes, thank you! They click in the wrong place in this article!

I only added APN key for development environment and forgot for production. Much thanks for the answer :D

the newer versions require this: [[FIRMessaging messaging] setAPNSToken:deviceToken type:FIRMessagingAPNSTokenTypeProd];
