I have a firebase DB set up with a topic so each time a user pushes a new message to the DB it sends a push notification to the users device
For some reason it is sending the notification to all devices.. I cannot figure out why its doing this 
Here is the function I've set up on firebase, And also my AppDelegate where it receives the push notification:
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
exports.sendNotification = functions.database
.ref('/messages/{uid}/{pushId}')
.onWrite( event => {
const newMessage = event.data.val();
console.log(newMessage.message);
const payload = {
notification: {
title: 'Loop',
body: newMessage.name + ' has interacted with his device',
sound: 'default'
},
data: {
name: newMessage.name,
message: newMessage.message
}
};
const options = {
priority: "high",
timeToLive: 60 * 60 * 24 //24 hours
};
return admin.messaging().sendToTopic("notifications", payload, options);
});
And heres the App Delegate:
import UIKit
import UserNotifications
import Firebase
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, MessagingDelegate, UNUserNotificationCenterDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
completionHandler(UIBackgroundFetchResult.newData)
}
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
Messaging.messaging().subscribe(toTopic: "notifications")
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().subscribe(toTopic: "notifications")
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
self.window = UIWindow(frame: UIScreen.main.bounds)
Utilities.decideInitialViewController(window: self.window!)
application.registerForRemoteNotifications()
return true
}
func applicationWillResignActive(_ application: UIApplication) {
}
func applicationDidEnterBackground(_ application: UIApplication) {
}
func applicationWillEnterForeground(_ application: UIApplication) {
}
func applicationDidBecomeActive(_ application: UIApplication) {
}
func applicationWillTerminate(_ application: UIApplication) {
}
}
