PushNotification with data only not received on iPhone

[kvowinckel]

What works:

I can send push notifications via FCM to my ionic app, as long as the message has next to data a notification as well. Both, on iOS and Android, the os notification is displayed when the app is in background. And in both, I can also work with the registered listener within the app to perform actions.

Server-side:

let message = {
    data: {key: value},
    notification: {
        title: title,
        body: subtitle
    },
    token: device
}

firebase_admin.messaging().send(message).catch(err => console.error(err));

App-side:

PushNotifications.addListener('pushNotificationReceived', 
      async (notification: PushNotification) => {

        alert(JSON.stringify(notification));
});

What does not work:

Now I also want to send a notification to the app, which is silently when the app is in the background, but triggers the registered listener, when the app is in foreground. Therefore, I am sending a data message via FCM (nit containing a notification). While this works in the Android App, nothing arrives in the iOS app.

let message = {
        data,
        token: device,
};
firebase_admin.messaging().send(message).catch(err => console.error(err));

I also tried to add

apns: {
    headers: { "apns-priority": "5", "apns-push-type": "background" },
    payload: { aps: { "content-available": 1 } }
}

without success.

Capacitor uses APNS for push notifications on iOS and they work fine, if you are using FCM then you probably did something wrong, sorry, I can't help you with that.
