iOS - Push Notification with custom data not being received in RemoteMessage

[ibnukipa]

I have correct setup the iOS project and why the remoteMessage is corrupted?

.

Not nearly enough information to understand the problem, nor propose any guesses.
My guess is that what you think you are sending as a remote message, is not what you are actually sending.

@mikehardy Sorry I'm not really good to asking. So, the RemoteMessage.data is always empty object on iOS but not in Android. is there any step I missed?

With the information you have provided, I can not say anything for certain.
All I can say is that when I my handlers are called in response to FCM, I have contents in the data property of the FCM JSON.

yeah, that's why I'm asking. with the same FCM JSON that send from the firebase admin, in my Android app is completely received.

in Android, messaging().onNotificationOpenedApp() or messaging().getInitialNotification() returning this

RemoteMessage {
 data: { screen: "profile", id: "123"  },
 notification: { body: 'new msg', title: 'Incoming Message' }
}

but in iOS, messaging().onNotificationOpenedApp() or messaging().getInitialNotification() with the same FCM JSON, it's retuning:

RemoteMessage {
 data: {},
 notification: { body: 'new msg', title: 'Incoming Message' }
}

the data property is only empty object in iOS, with the same FCM JSON
