Problems Notifications Firebase IOS - swift

Question

I've followed Apple's suggestions to implement push notifications with Firebase, but I can't get notifications. I have created the APNS key in firebase and I have activated the notifications in the app. In Siginig & Capabilities I have added "Push Notification" "Background Modules" activating Remote notifiactions. This is the code in AppDelegate:
import UIKit import FirebaseCore import FirebaseMessaging
#UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool{
//Firebase
FirebaseApp.configure()
// Push Notifications
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert,
.badge, .sound]
UNUserNotificationCenter.current()
.requestAuthorization(
options: authOptions,
completionHandler: {_, _ in})
application.registerForRemoteNotifications()
Messaging.messaging().subscribe(toTopic:"topic_general")
return true
}
}
extension AppDelegate: UNUserNotificationCenterDelegate{
// Push Notifications Mostrar aunque el movil este activo / Segundo Plano
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandle: #escaping
(UNNotificationPresentationOptions) -> Void){
completionHandle([.alert, .badge, .sound])
}
}
Problems Notifications Firebase IOS

Answer 1

I just looked through what you did and a working version of Firebase Notifications I have running. I would try to share where there are differences
import UIKit
import Firebase
import FirebaseMessaging
import FirebaseCore
Then
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
if #available(iOS 10.0, *) {
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(options: authOptions) { (status, pushError) in
if !status {
print(pushError?.localizedDescription as Any)
}
}
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
Messaging.messaging().delegate = self
return true
}
after which
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
let pushedInfo = notification.request.content.userInfo
print(pushedInfo, "JSON Content of the Push Notification")
}
My ideas as to why you might not be getting the notifications:
Push notifications can only be tested on a physical device. Doesn't work on simulator
It is possible that push notifications is not authorised on the device.
Kindly check these ideas and the code differences. It is highly possible that the issue is somewhere there.
PS: I don't remember why I checked for #available(iOS 10.0, *) the code is a bit old.
