Receiving notifications on iOS 9 but not iOS 10

[bellsaladin]

Hello, I'm facing a problem with notifications, i'm a not a able to receive notifications only on iOS 10. XCode returns the following error when i run the app on iOS 10 device :

<Error> [Firebase/Core][I-COR000003] The default Firebase app has not yet been configured. Add [FIRApp configure] to your application initialization.

Did anyone solve this issue ? Thanks.

I receive the same error on iOS 10( 10.3.3) . in iOS 9 and Android devices everything works fine. There's also no difference when using the plugin version 0.1.22, 0.1.23 or 0.1.24

Any possibility upgrading to SDK 4.1.1 will help? Anyone tried this? If not I will give it a go.

This issue might be caused by xCode i was using xCode 7. Now i use xCode 8 and my application can receive notifications on iOS 10+. Please confirm it if this solves your problem.

[sebastian312]

I use xCode 8.3.3 and still can't receive notifications on iOS 10.*

[bellsaladin]

I use cordova-plugin-firebase v0.1.22. Check if you use 0.1.24 it's known to be not compatible with iOS 10 yet.

[kirajhpang]

@jjosef you mean which SDK? ionic-iOS?

@bellsaladin I was use xCode 8 and no notification receive, I was suspect is because the connection from FCM to ASP take time to configure. But at the end, I was turn down this plugin and go for paid service, work well for me now so all platform.

[bellsaladin]

@kirajhpang jjosef suggested to change the Firebase SDK to 4.1.1. All i did for notifications to work on iOS 10 was switching back to cordova-plugin-firebase v0.1.22 and using xCode v8 instead of v7.

@bellsaladin I have the same problem. On iOS 9 it works and I receive the message in window.FirebasePlugin.onNotificationOpen() function. On iOS 10 this function isn`t called and nothing happens. Xcode Version is 8.3.3 plugin verison is now 0.1.22 The message is send via firebase console to one device.

[bellsaladin]

@wo-github i only tried notification while app is closed or in background so window.FirebasePlugin.onNotificationOpen() is not being used in this case. Didn't try foreground notifications yet.

[wo-github]

I make a update of cordova to 7.0 and update ios to 4.4 I receive now the data, if the app is open in the window.FirebasePlugin.onNotificationOpen() function. The next problem is, I receive nothing, if the app is in background. Does someone has an idea what could be the problem?

[wo-github]

I analyze the behavior with Xcode. If I open the app the console shows: Connected to FCM. InstanceID token: ##########

And if I close the app to background, the console shows: Disconnected from FCM

Could this be the problem? How could the app receive messages in backgroundmode?

[gioramies]

@wo-github I'm having the same issue. Console logs "Disconnected from FCM" when app goes to background. Please help.

Any luck with solving this issue? I also get this message and notifications don't work:

[Firebase/Messaging][I-FCM002019] FIRMessaging received data-message, but FIRMessagingDelegate's-messaging:didReceiveMessage: not implemented

[suresh-selvaraj]

Is this issue solved?

[bellsaladin]

@suresh-selvaraj @ourarash @gioramies @wo-github @sebastian312 @jjosef @jskidd3 @kirajhpang I had the same problem and to solve i did the following :

• was using xcode 7 updated it to xcode 8
• Downgraded cordova-plugin-firebase to v0.1.22 (which is the version i use actually)
• I checked the git commit with which i fixed this issue and i found these changes in the plist file set to true both NSAllowsArbitraryLoads & NSExceptionAllowsInsecureHTTPLoads params

These changes are required to fix a known issue with iOS related to Apple's ATS (App Transport Security). Check the links below for more details. I hope this helps.

Thank you @bellsaladin

I only tested my problem on iOS 9. It was that the notification didn't arrive when the app was in background. To fix it I followed the Google FCM documentation: https://firebase.google.com/docs/cloud-messaging/ios/certs and now it works (only tested on iOS9)

closing for now, reopen if still an issue with the latest version of the plugin
