I have implemented FCM. There is no error showing. Token successfully generated. But no notification coming into the device.
I followed the google documentations.
Here is my AppDelegate class
import Foundation
import UIKit
import Firebase
//https://github.com/firebase/quickstart-ios/blob/5694c29ac5a8dcc672ec13f55f0ab74a6b9af11e/messaging/MessagingExampleSwift/AppDelegate.swift#L40-L55
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, MessagingDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
FirebaseApp.configure()
Messaging.messaging().delegate = self
// 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 })
return true
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
print(userInfo)
}
// [START receive_message]
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
// Print full message.
print(userInfo)
completionHandler(UIBackgroundFetchResult.newData)
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("Unable to register for remote notifications: \(error.localizedDescription)")
}
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print("Firebase registration token: \(String(describing: fcmToken))")
let dataDict:[String: String] = ["token": fcmToken ?? ""]
NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
}
}
didReceiveRegistrationToken delegate method callings twice
Here is my Capabilities
I tried send notification from firebase cloud messaging option, but not coming to any Push in device.
I also tried from postman. Here is my payload and output
I have uploaded the APNS certificate in firebabse .
I tried into main project and its not working.
Then I tried to fresh implement into a dummy project its also not working.
Here is my source code. You may check into this.
https://www.dropbox.com/s/22wojqv5u3vwjzt/Swift%20UI%20Push%20Notification.zip?dl=0
I think the payload is different for APNS.From the document I found that the following is the format for FCM payload in APNS
{
"message": {
"token" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"notification" : {
"body" : "This is an FCM notification that displays an image.!",
"title" : "FCM Notification",
},
"apns": {
"payload": {
"aps": {
"mutable-content": 1
}
},
"fcm_options": {
"image": "url-to-image"
}
}
}
}
You can add all the UNUserNotificationCenterDelegate method along with completionHandler([.alert, .badge, .sound]).

I've linked my Swift Storyboard project with Firebase push notifications.
The notifications are currently arriving, but the problem is that the notifications are coming without sound or badge to display.
If I check the notification.request.content.sound or notification.request.content.badge... is displaying nil...
Anyone has face this? Do I missing something in the code to recieve the notification with the sound and badge?
class AppDelegate: UIResponder, UIApplicationDelegate {
var fcmTokenPreviafy: String = ""
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
FirebaseApp.configure()
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: { _, _ in }
)
application.registerForRemoteNotifications()
Messaging.messaging().delegate = self
return true
}
}
And here are the extensions:
extension AppDelegate: UNUserNotificationCenterDelegate{
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification) async -> UNNotificationPresentationOptions {
let userInfo = notification.request.content.userInfo
print(userInfo)
return [[ .alert, .badge, .sound ]]
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse) async {
let userInfo = response.notification.request.content.userInfo
print(userInfo)
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) async -> UIBackgroundFetchResult {
print(userInfo)
return UIBackgroundFetchResult.newData
}
}
extension AppDelegate: MessagingDelegate{
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String?) {
print("Firebase registration token: \(String(describing: fcmToken))")
let dataDict: [String: String] = ["token": fcmToken ?? ""]
NotificationCenter.default.post(
name: Notification.Name("FCMToken"),
object: nil,
userInfo: dataDict
)
fcmTokenPreviafy = fcmToken!
// TODO: If necessary send token to application server.
// Note: This callback is fired at each app startup and whenever a new token is generated.
}
}
I am sending push notification by using FCM and PushTry, While the app is in suspended mode (App is closed) notification is coming but while app in foreground mode (App is open) notification coming but not showing banner.
didReceiveRemoteNotification notification method is calling when app in foreground mode and print data but not showing banner.

}
}
Print:-

Question: Can someone please explain to me how to show banner when app in foreground mode, I've tried with above code but no results yet. If i'm doing wrong please correct me.
Can someone please explain to me show notification banner?
Any help would be greatly appreciated.
Thanks in advance.
I am setting up push notifications, and everything is going well until I try to get the FCM token so I can send a test message to an actual device. Using the pods Firebase 5.8.0, FirebaseCore (5.1.3), FirebaseInstanceID (3.2.1), and FirebaseMessaging (3.1.2), I can get the APNS token fine but every time I try to get the FCM token, it comes out as nil or when I use InstanceID.instanceID().instanceID(handler:) it results in some timeout error code 1003 and a result of nil. didReceiveRegistrationToken does not get called either. I've tried a many 2017 solutions but they're either deprecated or don't work. MessageDelegate and UNUserNotificationCenterDelegate are set, push notifications, and keychain sharing are enabled in capabilities, method swizzling is off via p-list and Here is my didRegisterForRemoteNotificationsWithDeviceToken function where I correctly get the apns token. Any ideas? Thanks.
`public func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
print("Registration Successful: Device token \(deviceToken)")
Messaging.messaging().apnsToken = deviceToken
print("Messaging APNS Token:\(Messaging.messaging().apnsToken)")
print("Instance Id: \(InstanceID.instanceID().token())") //deprecated & returns nil
print("Messaging APNS Token:\(Messaging.messaging().apnsToken)")
print("Token:\(Messaging.messaging().fcmToken)") // return nil
InstanceID.instanceID().instanceID { (result, error) in
if let result = result {
print("Result:\(String(describing: result?.token))")
} else {
print("Error:\(error))")
} //returns after about 2 mins with an firebase iid error of 1003
}
Please check the below app delegate code.

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 include google firebase in my app - create google account, create google app, upload APNS certifications (.pem and in work in another service), and send push notifications from console, and my app not receive it. In Firebase console i see status complete but Approximate number of devices is "-"
Of course I updated provisions profiles and APNS cert
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Register for remote notifications
if #available(iOS 8.0, *) {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
} else {
// Fallback
let types: UIRemoteNotificationType = [.Alert, .Badge, .Sound]
application.registerForRemoteNotificationTypes(types)
}
FIRApp.configure()
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.tokenRefreshNotificaiton),
name: kFIRInstanceIDTokenRefreshNotification, object: nil)
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
print(userInfo)
}
func tokenRefreshNotificaiton(notification: NSNotification) {
if let refreshedToken = FIRInstanceID.instanceID().token() {
print("InstanceID token: \(refreshedToken)")
User.sharedUser.googleUID = refreshedToken
}
}
func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forRemoteNotification userInfo: [NSObject : AnyObject], withResponseInfo responseInfo: [NSObject : AnyObject], completionHandler: () -> Void) {
print(userInfo)
}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Prod)
}
func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forRemoteNotification userInfo: [NSObject : AnyObject], withResponseInfo responseInfo: [NSObject : AnyObject], completionHandler: () -> Void) {
print(userInfo)
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
print(userInfo)
}
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
print("ошибка")
print(error)
print(error.description)
}
The first thing I see is there's no call to connect to FIRMessaging. Try adding this to your AppDelegate:
func applicationDidBecomeActive(application: UIApplication) {
FIRMessaging.messaging().connectWithCompletion { error in
print(error)
}
}
Use the following code.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
if #available(iOS 10.0, *)
{
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.currentNotificationCenter().delegate = self
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert]) { (granted, error) in
if granted
{
//self.registerCategory()
}
}
// For iOS 10 data message (sent via FCM)
FIRMessaging.messaging().remoteMessageDelegate = self
}
else
{
let settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: [.Alert,.Badge,.Sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
//Configuring Firebase
FIRApp.configure()
// Add observer for InstanceID token refresh callback.
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.tokenRefreshNotification), name: kFIRInstanceIDTokenRefreshNotification, object: nil)
return true
}
//Receive Remote Notification on Background
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void)
{
FIRMessaging.messaging().appDidReceiveMessage(userInfo)
}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData)
{
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Sandbox)
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Prod)
}
func tokenRefreshNotification(notification: NSNotification)
{
if let refreshedToken = FIRInstanceID.instanceID().token()
{
print("InstanceID token: \(refreshedToken)")
}
// Connect to FCM since connection may have failed when attempted before having a token.
connectToFcm()
}
func connectToFcm()
{
FIRMessaging.messaging().connectWithCompletion { (error) in
if (error != nil)
{
print("Unable to connect with FCM. \(error)")
}
else
{
print("Connected to FCM.")
}
}
}
func applicationDidBecomeActive(application: UIApplication)
{
connectToFcm()
}
You might be using Data or aps key in PUSH JSON which is used to send notifications to devices. It should work properly but in rare cases, it not works, even it'll give you success in fcm/send api but notification will not reach particular devices. This problem usually occurs in iOS devices.
A solution which worked for me is add notification key instead of Data.
{
"to" : "device token",
"notification":{
"body": "test",
"title": "test"
}
}
If you are sending from Backend OR you don't have access of Firebase console. Then you can test and send notification via POSTMAN also. But you must have SERVER KEY, which can be got from Firebase console under Cloud Messaging settings.
API: https://fcm.googleapis.com/fcm/send
Method: POST
Headers:
"Content-Type"=application/json
"Authorization"="key=YOUR SERVER KEY" //You must add key= above the server key.
{
"to" : "your device token",
"notification":{
"body": "test",
"title": "test"
}
}
ANOTHER DETAILED AND FULL PAYLOAD IF YOU NEED TO SEE WHAT WE CAN SEND IN FIREBASE NOTIFICATION:
{
"to":"device token",
"notification":{
"data":{
"avatar":"",
"body":"",
"key_notification":"0",
"type_notification":"1",
"deviceToken":"device token",
"badge":1,
"message":"your text"
},
"text":"your text",
"sound":"sound.caf",
"badge":21
},
"priority":"high"
}
