I've implemented Firebase Cloud Messaging as per instructions given on their website. So when I generate notification from here:
And in AppDelegate.swift I've added didReceiveRemoteNotification function as:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
Messaging.messaging().appDidReceiveMessage(userInfo)
print(userInfo)
completionHandler(UIBackgroundFetchResult.newData)
}
Other methods I've implemented are
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String)
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage)
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
Whereas my didFinishLaunchingWithOptions has:
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
Messaging.messaging().delegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
FirebaseApp.configure()
NotificationCenter.default.addObserver(self, selector: #selector(self.tokenRefreshNotification), name: NSNotification.Name.InstanceIDTokenRefresh, object: nil)
return true
Please take a look this gist file
AppDelegate file for FCM
In XCode Goto Targets > Capabilities & make sure your Push Notifications is on.
Hope it helps.

I am getting stuck on push notification. When I am installing the app first time then the firebase notification does not trigger, but after killing one and open again app it's working fine.
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
// Use Firebase library to configure APIs
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,
completionHandler: {_, _ in })
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
Messaging.messaging().delegate = self
Messaging.messaging().isAutoInitEnabled = true
return true
}
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print("Firebase registration token: \(String(describing: fcmToken))")
UserDefaults.standard.setValue(fcmToken, forKey: "Token")
let dataDict:[String: String] = ["token": fcmToken ]
NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
// TODO: If necessary send token to application server.
// Note: This callback is fired at each app startup and whenever a new token is generated.
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
}
I am running into a very weird problem. After uninstalling and reinstalling my iOS 11 app (coded in swift), I have to launch the app multiple times (10 to 20) before my firebase messaging works again. I change nothing in the code (sometimes I just wait and hour or so) and for some reason it seems that Firebase Messaging Notifications only work after relaunching my app multiple times. It's very important for my app to be able to receive notifications right when it's first opened as my app is basically reliant on them. I just need to find a way to get notifications to work when I first launch the app after I install it. I've attached images of my code. (I have method_swizzling enabled)
If someone could please help me I would really appreciate it. I've seen youtube videos doing the same things I'm doing and they're able to get messages to work right away. I've tried a lot of what I've seen online and other questions that seem to be like this but none of their methods seem to work. Thank you so much to anyone who tries to help!
[edit]
This is the code for the application launch function:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
application.statusBarStyle = ColorScheme.isDark ? .lightContent : .default
FirebaseApp.configure()
// Messaging.messaging().delegate = self
// Messaging.messaging().shouldEstablishDirectChannel = true
// UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .alert, .sound]) { (granted, error) in }
// application.registerForRemoteNotifications()
setupMessaging(application: application)
}
This is the code for actually connecting and setting up my Firebase Messaging:
extension AppDelegate {
func setupMessaging(application: UIApplication) {
Messaging.messaging().delegate = self
Messaging.messaging().shouldEstablishDirectChannel = true
print("channel established", Messaging.messaging().isDirectChannelEstablished)
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(options: authOptions, completionHandler: {_, _ in })
} else {
let settings: UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().setAPNSToken(deviceToken, type: .sandbox)
//TODO: Change for release
}
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
}
}
And this is the debug functions that are called when I receive the notification:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
print("I got a notification")
print(userInfo)
}
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
print("remote message received")
}
P.S. my AppDelegate extends MessagingDelegate and UNUserNotificationCenterDelegate
Please Check the below code
import Firebase
import FirebaseMessaging
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, MessagingDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
Messaging.messaging().delegate = self
//REMOTE NOTIFICATION
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 })
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
Messaging.messaging().delegate = self
let token = Messaging.messaging().fcmToken
print("FCM token: \(token ?? "")")
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self
} else {
// Fallback on earlier versions
}
return true
}
func application(_ application: UIApplication,
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken as Data
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
// Print full message.
print(userInfo)
}
// This method will be called when app received push notifications in foreground
#available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void)
{
completionHandler([UNNotificationPresentationOptions.alert,UNNotificationPresentationOptions.sound,UNNotificationPresentationOptions.badge])
}
// MARK:- Messaging Delegates
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
InstanceID.instanceID().instanceID { (result, error) in
if let error = error {
print("Error fetching remote instange ID: \(error)")
} else if let result = result {
print("Remote instance ID token: \(result.token)")
}
}
}
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
print("received remote notification")
}
}
I found the answer! The problem was that I was using the online console firebase provides to send my test messages. I guess it time to register devices. I switched over to firebase functions to send my notification and then subscribed to a test topic with my phone and that fixed everything. I get notifications on first app launch now and I'm happy
In my app I am trying to set up Push notifications Using Firebase Cloud Messaging.
When I try and send a notification using a single device and FCM key, I receive the notification. However, it does not work for User segment when I select the targeted app.
Here is my App delegate setup:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Firebase
FirebaseApp.configure()
FirebaseConfiguration.shared.setLoggerLevel(.min)
// Push notifications
application.registerForRemoteNotifications()
setupPush(application: application)
if #available(iOS 10.0, *) {
let authOptions : UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_,_ in })
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
// For iOS 10 data message (sent via FCM)
Messaging.messaging().delegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
UIApplication.shared.registerUserNotificationSettings(settings)
}
UIApplication.shared.registerForRemoteNotifications()
}
#available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
// iOS10+, called when presenting notification in foreground
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
NSLog("[UserNotificationCenter] applicationState: \(applicationStateString) willPresentNotification: \(userInfo)")
//TODO: Handle foreground notification
completionHandler([.alert])
}
// iOS10+, called when received response (default open, dismiss or custom action) for a notification
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
NSLog("[UserNotificationCenter] applicationState: \(applicationStateString) didReceiveResponse: \(userInfo)")
//TODO: Handle background notification
completionHandler()
}
// Setup APNS token for Firebase
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
#if PROD_BUILD
Messaging.messaging().setAPNSToken(deviceToken, type: .prod)
#else
Messaging.messaging().setAPNSToken(deviceToken, type: .sandbox)
#endif
}
extension AppDelegate : MessagingDelegate {
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
NSLog("[RemoteNotification] didRefreshRegistrationToken: \(fcmToken)")
}
// iOS9, called when presenting notification in foreground
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
NSLog("[RemoteNotification] applicationState: \(applicationStateString) didReceiveRemoteNotification for iOS9: \(userInfo)")
if UIApplication.shared.applicationState == .active {
//TODO: Handle foreground notification
} else {
//TODO: Handle background notification
}
}
I have integrated Firebase into my project and I think I have followed all the steps required for generating push notifications within the app. I have also tested the push notifications by sending some dummy notifications from the Firebase console.
This is the tutorial I entirely followed.
Now my questions are..
How will I get the FCM ID so that I can send it in my api call.
When a push notification comes, where do I handle it..?
Where do I mention things like when to receive the notifications and the actions to take while tapping on notifications..?
EDIT 1
So this is all the code I have for handling push notifications...
In didFinishLaunchingWithOptions...
if #available(iOS 10.0, *) {
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_, _ in })
// For iOS 10 data message (sent via FCM
Messaging.messaging().delegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
FirebaseApp.configure()
And then,
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
let token = Messaging.messaging().fcmToken
print("FCM token: \(token ?? "")")
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]){
print("userInfo:-> \(userInfo)")
}
Q1 :- First Method
Q2&3 :- Second Method
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
let token = Messaging.messaging().fcmToken
print("FCM token: \(token ?? "")")
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]){
print("userInfo:-> \(userInfo)")
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
print("userInfo:-> \(userInfo)")
let redirect_flag = userInfo["redirect_flag"]as! String
if application.applicationState == .inactive {
// handle when you background
}
}else{
// Here You need to handle all terms which you handle in
didReceiveRemoteNotification method
}
I am not able to receive the notification from firebase. I have updated all pods and also uploaded the APNs Certificates for production. In Xcode i am managing the provisioning profile automatically and also enabled push notification, Remote notification(inside Background modes) in capabilities. Notification is enabled in setting section of device.
Here is my code in App delegate.
import UserNotifications
import Firebase
import FirebaseInstanceID

let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_, _ in })
// For iOS 10 data message (sent via FCM
Messaging.messaging().delegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
FirebaseApp.configure()
}
func application(_ application: UIApplication,
didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
Messaging.messaging().appDidReceiveMessage(userInfo)
// Print message ID.
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
completionHandler(UIBackgroundFetchResult.newData)
}
func application(_ application: UIApplication,
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken
}
func applicationDidBecomeActive(_ application: UIApplication) {
Messaging.messaging().connect { error in
}
}

//Here i do my navigation according to notification type
}
func userNotificationCenter(_ center: UNUserNotificationCenter,
