Swift IOS 10 Firebase Push Notification - swift

Question

Hello there I receive notifications on iOS 9 but not on devices with
iOS 10 installed. What could be the problem?
import UIKit
import CoreData
import Firebase
import FirebaseMessaging
import UserNotifications
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,UNUserNotificationCenterDelegate ,FIRMessagingDelegate {
public func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
print(remoteMessage.appData)

UINavigationBar.appearance().barTintColor = UIColor(red: 50.0/255, green: 150.0/255, blue: 65.0/255, alpha: 1.0)
//create the notificationCenter
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,
completionHandler: {_, _ in })
// For iOS 10 data message (sent via FCM
FIRMessaging.messaging().remoteMessageDelegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
FIRApp.configure()
return true
}

var token = ""
for i in 0..<deviceToken.count {
token = token + String(format: "%02.2hhx", arguments: [deviceToken[i]])
}
print("Registration succeeded! Token: ", token)
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("Registration failed!")
}
func applicationWillResignActive(_ application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}
func applicationDidEnterBackground(_ application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
func applicationWillEnterForeground(_ application: UIApplication) {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(_ application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
func applicationWillTerminate(_ application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
// Saves changes in the application's managed object context before the application terminates.

Typical reasons for an error here include:
* The parent directory does not exist, cannot be created, or disallows writing.
* The persistent store is not accessible, due to permissions or data protection when the device is locked.
* The device is out of space.
* The store could not be migrated to the current model version.
Check the error message to determine what the actual problem was.

Answer 1

You need to implement the App Delegate method:
application(_:didReceiveRemoteNotification:fetchCompletionHandler:)
This will get called when app is not in the foreground.
You are currently implementing:
userNotificationCenter(_ center: UNUserNotificationCenter, didReceive ...
but this one works when the app is in the foreground only.

Answer 2

Please implement below two methods
func application(_ application: UIApplication,didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
}
func application(_ application: UIApplication,didReceiveRemoteNotification userInfo: [AnyHashable: Any],fetchCompletionHandler completionHandler: #escaping(UIBackgroundFetchResult) -> Void) {
completionHandler(UIBackgroundFetchResult.newData)
}
