Data-only notification not received on react native iOS app

[niharikaargade]

Sending a data-only notification from FCM to a react-native iOS app in foreground is not received by react-native-firebase/messaging onMessage() method. However it works for an android app and for iOS if we send data + notification message. A notification-only message works completely fine on iOS and android getting this issue for data-only message.

package.json

"@react-native-firebase/app": "10.0.0",
"@react-native-firebase/crashlytics": "10.0.0",
"@react-native-firebase/messaging": "10.0.0"

Podfile

  pod 'Firebase/Core'
  pod 'Firebase/Firestore'
  pod 'Firebase/Messaging'

Payload

   {
    "message":{
    "token":"TOKEN",
    "data":{
      "Nick" : "Mario",
      "body" : "great match!",
      "Room" : "PortugalVSDenmark"
     }
   }
 }

App.js

async componentDidMount() {
        //Get notification permission from user and token
        await this.checkPermission();
        
        messaging().onMessage(async remoteMessage => {
            console.log("Remote notification inside onMessage" + JSON.stringify(remoteMessage));
        });

        messaging().onNotificationOpenedApp(remoteMessage => {
            console.log('Notification caused app to open from background state:', remoteMessage);
        });

        // Check whether an initial notification is available
        messaging().getInitialNotification().then(remoteMessage => {
            if (remoteMessage) {
                console.log(
                    'Notification caused app to open from quit state:',
                    remoteMessage.notification,
                );
  
            }
        });
    }

Please search the roughly 1,000 related data-only not coming on iOS messages in this issues list
Pay special attention to the search term "unreliable"

Thanks for responding, I have actually read all the data-only related issues present on the discussion and I have also come across one of your comments talking about how data-only notifications do not work when app is in background; so does that also apply to when the app is in foreground as well ? If yes, is there an efficient work around for it ? As we only need the data-only notification when the app is in foreground.

data-only definitely works in foreground, if it is not working then something is wrong with your project, either wrong entitlements or wrong payload used or wrong implementation of handlers etc. I never have a problem with foreground delivery.

Ohh thank you so much for confirming this. I will try integrating react-native-firebase with my project again.
