iOS FCM not getting push notifications - ios

Question

Since i updated to swift 3, FCM doesn't work.
Push Notifications are enabled in Capabilities and Certificates are updated on Firebase console.
Btw, fcm on android app works just fine, and it was working on ios but after update on swift 3 and new firebase libraries, it doesn't.
AppDelegate.swift:
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
let notificationCenter = NotificationCenter.default
var connectedToFcm: Bool = false
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let settings: UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
FIRApp.configure()
NotificationCenter.default.addObserver(self, selector: #selector(self.tokenRefreshNotification), name: NSNotification.Name.firInstanceIDTokenRefresh, object: nil)
return true
}
func applicationDidEnterBackground(_ application: UIApplication) {
disconnectFromFcm()
}
func applicationDidBecomeActive(_ application: UIApplication) {
connectToFcm()
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
print("REGISTRED")
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: .unknown)
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError
error: Error ) {
print("Registration for remote notification failed with error: \(error.localizedDescription)")
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
print(userInfo)
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
print(userInfo)
}
func tokenRefreshNotification(_ notification: Notification) {
let refreshedToken = FIRInstanceID.instanceID().token()
if refreshedToken != nil {
print("InstanceID token: \(refreshedToken!)")
// Connect to FCM since connection may have failed when attempted before having a token.
connectToFcm()
}
}
func connectToFcm() {
guard FIRInstanceID.instanceID().token() != nil else {
return;
}
if connectedToFcm == false {
FIRMessaging.messaging().disconnect()
FIRMessaging.messaging().connect { (error) in
if (error != nil) {
self.connectedToFcm = false
print("Unable to connect with FCM. \(error)")
} else {
self.connectedToFcm = true
print("Connected to FCM.")
self.sendTokenToServer()
}
}
return
}
}
func sendTokenToServer() {
let fcmToken = FIRInstanceID.instanceID().token()
if self.sharedUser.getToken().characters.count == 0 || fcmToken == nil {
return
}
let params = [
"reg_id": fcmToken!,
"dev_id": Config().devId
]
Alamofire.request(Config().fcmUrl, method: .post, parameters: params, encoding: JSONEncoding.default, headers: Config().apiHeaders)
.validate()
.responseJSON { response in
if response.result.isSuccess {
print("FCM token send to app server")
}
}
}
func disconnectFromFcm() {
FIRMessaging.messaging().disconnect()
connectedToFcm = false
print("Disconnected to FCM")
}
}

Connected to FCM.
FCM token send to app server
I made prints to check if app gets token, and it does. Also, token is sent to server and i checked there if it is ok and if server is sending push.

Answer 1

I have faced same issue with iOS FCM integration I have solved it by using latest code for push notification in iOS 10.
You need to check the OS version of the device and segregate relevant codes.
if #available(iOS 10, *)
{
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
if error == nil{
UIApplication.shared.registerForRemoteNotifications()
}
}
}else
{
// Register for remote notifications
if #available(iOS 8.0, *) {
// [START register_for_notifications]
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
// [END register_for_notifications]
} else {
// Fallback
let types: UIRemoteNotificationType = [.alert, .badge, .sound]
application.registerForRemoteNotifications(matching: types)
}
}
Put this code in a function and call it from did finish launching also comment your code.
Do let me know if you still have any issues.
Important :- import UserNotifications
Delegate :-
func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings)
{
/**
Allow device to register for remote notification.
*/
UIApplication.shared.registerForRemoteNotifications()
FIRMessaging.messaging().subscribe(toTopic: "/topics/test")
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
{
/**
Send device token to firebase to get the FCM token for pushnotification from firebase.
*/
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.prod)
}
