Push is not coming on Release builds after update from 5.15 to 5.16 #2365

  • Xcode version: 10.1
  • Firebase SDK version: 5.16
  • Firebase Component: Core, Messaging
  • Component version: Core 5.16.0, Messaging 3.3.0


Recently I've updated pods using specs:

  pod 'Firebase/Core', '~> 5.0', :inhibit_warnings => true
  pod 'Firebase/Messaging', '~> 5.0', :inhibit_warnings => true
  pod 'Firebase/DynamicLinks', '~> 5.0', :inhibit_warnings => true
  pod 'Firebase/RemoteConfig', '~> 5.0', :inhibit_warnings => true

which made an upgrade from:

   Firebase/Core (5.15.0) -> 5.16.0
     FirebaseAnalytics (= 5.5.0) -> 5.4.0

   Firebase/Messaging (5.15.0): -> 5.16.0
     FirebaseMessaging (= 3.2.2) -> 3.3.0

   Firebase/DynamicLinks (5.15.0): -> 5.16.0
     FirebaseDynamicLinks (= 3.3.0) -> 3.4.0

   Firebase/CoreOnly (5.15.0): -> 5.16.0
     FirebaseCore (= 5.1.10) -> 5.2.0

 FirebaseInstanceID 3.3.0 -> 3.4.0

The issues is - in DEBUG configuration - I'm receiving Push Notifications. But when exported for Production (AdHoc and AppStore) builds - no Push Notifications.

Steps to reproduce:

  1. Install
pod 'Firebase/Core', '~> 5.16.0', :inhibit_warnings => true
pod 'Firebase/Messaging', '~> 5.16.0', :inhibit_warnings => true
  1. Run App in DEBUG configuration

  2. Send Push notification - Push is delivered to device

  3. Change XCode Scheme settings. For Run :
    4.1 select build configuration = Release (or some which is used for AdHoc distribution)
    4.2 uncheck 'Debug executable' - this is necessary to run release build on device

Alternatively you may distribute AdHoc or AppStore build via any system you use (TestFlight, HockeyApp, AppCenter, Crashlytics).

  1. Send Push notification

Expected - Push is delivered

Actual - Push is not delivered

In console log I see:
5.16.0 - [Firebase/InstanceID][I-IID003009] Failed to fetch default token Error Domain=com.firebase.iid Code=1005 "(null)"

and strange line:
5.16.0 - [Firebase/Core][I-COR000003] The default Firebase app has not yet been configured. Add [FIRApp configure]; (FirebaseApp.configure() in Swift) to your application initialization. Read more:

despite the fact it is configured in:

func application(_ application: UIApplication,
                     didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

Rolling back to 5.15.0 has solved the issue.

Same. Thanks @emartinson

I faced the same issue I think. Firebase messaging 3.3.0. First install - push is working on iPhone 5s, second launch of the app, push is not working.

This how I was sent by firebase support:

Thanks for reaching out.
I'd first suggest updating to the latest version of the SDKs. Try also sending directly to the device and testing with the quickstart, to see if it's a problem with local to the device. If that doesn't help, check out this blogpost on debugging FCM for iOS, which contains lots of useful information - particularly step #4, sending directly through APNs, as lots of delivery problems on iOS are related to APNs problems.

Thanks for the report and sorry about the issues. It sounds like another Firebase SDK is attempting to get InstanceID before Core is configured. We'll try to track this down to figure out what happened and get back ASAP. If things are broken in production, it may make sense for you to roll back to 5.15.0 for now until we get this resolved.

@emartinson Thanks for the detailed info. Do you happen to call any Firebase API before [FIRApp configure] call?

Copy link

@emartinson just wanted to check - is the version of Firebase Analytics correct from your pasted output?

FirebaseAnalytics (= 5.5.0) -> 5.4.0

The version of Analytics set with Firebase 5.16.0 still 5.5.0

Copy link

Please fix the issue as soon as possible. I also have troubles with receiving push messages after updating Firebase to the latest version.

@emartinson Thanks for the detailed info. Do you happen to call any Firebase API before [FIRApp configure] call?

I suppose not. We found this issue during regress and checked almost all changes since latest release - no calls before [FIRApp configure]

@emartinson just wanted to check - is the version of Firebase Analytics correct from your pasted output?

FirebaseAnalytics (= 5.5.0) -> 5.4.0

The version of Analytics set with Firebase 5.16.0 still 5.5.0

Yes. that's correct. That might happen because we used ~> 5.0 for all Firebase pods:

pod 'Firebase/Core', '~> 5.0', :inhibit_warnings => true
pod 'Firebase/Messaging', '~> 5.0', :inhibit_warnings => true
pod 'Firebase/DynamicLinks', '~> 5.0', :inhibit_warnings => true
pod 'Firebase/RemoteConfig', '~> 5.0', :inhibit_warnings => true

I also saw this line during updating cocoapods:

Installing FirebaseInstanceID 3.4.0 (was 3.3.0 ...

@tipoc123 Can you also share the log when you run "pod update"?

Possibly, my push messages are not working because of other reason. For example, my apple developer account is in process of migration from an individual to an organization. I'm waiting for the end of migration and will check push messages again.

Copy link

@tipoc123 Yeah if your apple developer account is updated, your APNS token will change and old FCM token will not work. The client will update with the new FCM token that can be used to send notification.

This should be addressed in 5.17.0 which was released today. Please re-open if you still have issues.

Hi @ryanwilson , we still have issues even in 5.20.1 and it all started after updating from 5.15 (we did the update in January and that's when we started receiving push notifications not working reports). It seems people have been reporting since 5.16 in another closed issue: #2372. Should we reopen either?
edit: #2438 seems to be the new place 👍
