Push notification not receiving in iOS swift?
I am using FCM
push notifications. FCM
connected, the device is registered successfully and I can print the device token, but the device does not receive notification. In general -> features tab -> enabled push notification and remote notification in reverse land mode.
The device for remote notification is registered here.
func application(
_ application: UIApplication,
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data
) {
let trimEnds:String! = {
deviceToken.description.trimmingCharacters(
in: CharacterSet(charactersIn: "<>"))
}()
let cleanToken:String! = {
trimEnds.replacingOccurrences(of: " ", with: "")
}()
let token = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
print(token)
UserDefaults.standard.set(token, forKey: "deviceToken")
UserDefaults.standard.synchronize()
#if DEBUG
//For Firebase
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.sandbox)
#else
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.prod)
#endif
print("Device Token:", token)
}
Here I called the method didReceiveRemoteNotification
to receive notifications on the registered device:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
print("-=-=-=-=-\nDid receive notification\n-=-=-=-",userInfo)
print("-=-=-=-=-\n")
NotificationCenter.default.post(name: Notification.Name(rawValue: "notification_recieved"), object: nil)
if userInfo.index(forKey: "chat_id") != nil {
print("messag push")
if (AppUtility?.hasValidText(User.userID))! {
//let friendImage = userInfo["path"] as! String
let chatID = userInfo["chat_id"] as! String
let friendId = userInfo["to"] as! String
let unRead = userInfo["unread"] as! String
print(unRead)
UnReadMsgs = unRead
let dictAPS = userInfo["aps"] as! NSDictionary
let dict = dictAPS["alert"] as! NSDictionary
let friendName = dict["title"] as! String
let friendMsg = dict["body"] as! String
if(UIApplication.shared.applicationState == UIApplicationState.active){
print("app is Active")
if let wd = self.window {
var VC = wd.rootViewController
if(VC is UINavigationController){
VC = (VC as! UINavigationController).visibleViewController
if(VC is ChatViewController!){
print("Chat Screen")
let chatVC : ChatViewController = VC as! ChatViewController
if chatVC.chatId == chatID{
print("Same Chat")
self.clearChatWithChatID(chatID)
}else{
CustomNotificationView.showNotificationPopUp(self.window!, name: friendName, msg: friendMsg, image: "", chat: chatID, friendID: friendId)
playSound()
print("Other Chat")
}
}else{
let nc = NotificationCenter.default
nc.post(name: Notification.Name(rawValue: "MessageGet"),
object: nil,
userInfo: ["unRead":unRead,
"date":Date()])
CustomNotificationView.showNotificationPopUp(self.window!, name: friendName, msg: friendMsg, image: "", chat: chatID, friendID: friendId)
playSound()
print("Other Screen")
}
}
}
}else{
print("app is in BG")
var vc:ChatViewController!
vc = ChatViewController(nibName: "ChatViewController", bundle: nil)
vc.chatId = chatID
vc.otherUserId = friendId
vc.otherUserName = friendName
vc.channelRef = self.channelRef.child("\(chatID)")
vc.friendImageLink = "\(resourceUrl)\("")"
let nav = UINavigationController(rootViewController: vc)
nav.isNavigationBarHidden = false
if let wd = self.window {
var VC = wd.rootViewController
if(VC is UINavigationController){
VC = (VC as! UINavigationController).visibleViewController
}
VC!.present(nav, animated: false, completion: {
})
}
}
}
}else{
let val = userInfo["aps"] as! [String:AnyObject];
let alert = NSString(string: val["alert"] as! String)
if(UIApplication.shared.applicationState == UIApplicationState.inactive || UIApplication.shared.applicationState == UIApplicationState.background)
{
showUserInfo(application, didReceiveRemoteNotification: userInfo)
}
else
{
print("top most vc \(String(describing: UIApplication.shared.keyWindow!.rootViewController!.topMostViewController().presentingViewController)) and presentedvc \(String(describing: UIApplication.shared.keyWindow!.rootViewController!.topMostViewController().presentedViewController))")
if UIApplication.shared.keyWindow!.rootViewController!.topMostViewController() is NYAlertViewController{
let newAlert = AppUtility?.getDisplayAlertController(title: "FitFlow", messageText: alert as String)
let nvVc = UIApplication.shared.keyWindow!.rootViewController!.topMostViewController().presentedViewController
nvVc?.present(newAlert!, animated: true, completion: nil)
return
}
AppUtility?.displayAlert(title:"FitFlow", messageText: alert as String,UIApplication.shared.keyWindow!.rootViewController!.topMostViewController())
}
}
}
I tested by keeping breakpoints, it is not called a method at all didReceiveRemoteNotification
. How do I get a push notification using the above method?

I've also been stuck with this before.
This requires an FCM token , not an APNS token .
To do this, your AppDelegate class must have these -
import Firebase
import UserNotifications
import FirebaseMessaging
class AppDelegate: UIResponder,
UIApplicationDelegate,
UNUserNotificationCenterDelegate,
FIRMessagingDelegate {
}
- Then sign the messaging delegate in
didFinishLaunchingWithOptions
func application(_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
GIDSignIn.sharedInstance().clientID =
"Your client id"
DispatchQueue.main.async {
FIRApp.configure()
}
FIRMessaging.messaging().remoteMessageDelegate = self
if #available(iOS 10, *) {
UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]){ (granted, error) in }
application.registerForRemoteNotifications()
}
// iOS 9 support
else if #available(iOS 9, *) {
UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
UIApplication.shared.registerForRemoteNotifications()
}
// iOS 8 support
else if #available(iOS 8, *) {
UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
UIApplication.shared.registerForRemoteNotifications()
}
// iOS 7 support
else {
application.registerForRemoteNotifications(matching: [.badge, .sound, .alert])
}
return true
}
// You don't need the didRegisterForRemoteNotificationsWithDeviceToken method anymore
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { }
the token you received from the delegate
didRegisterForRemoteNotificationsWithDeviceToken
is not useful,You need to use FIRInstanceID.instanceID (). token ()
Add the below code to your applicationDidBecomeActive, this will check for FCM token updates and handle it elegantly.
func applicationDidBecomeActive(_ application: UIApplication) {
NotificationCenter.default.addObserver(self, selector:
#selector(tokenRefreshNotification), name:
NSNotification.Name.firInstanceIDTokenRefresh, object: nil)
}
@objc func tokenRefreshNotification(notification: NSNotification) {
if let refreshedToken = FIRInstanceID.instanceID().token() {
print("InstanceID token: \(refreshedToken)")
UserDefaults.standard.set(refreshedToken, forKey: "deviceToken")
self.sendFCMTokenToServer(token: refreshedToken)
}
/*
Connect to FCM since connection may
have failed when attempted before having a token.
*/
else {
connectToFcm()
}
}
func updatePushNotificationWebservice() {
/*
if you want to save that token on your server
Do that here.
else use the token any other way you want.
*/
}
func connectToFcm() {
FIRMessaging.messaging().connect { (error) in
if (error != nil) {
print("Unable to connect with FCM. \(String(describing: error))")
}
else {
print("Connected to FCM.")
/*
**this is the token that you have to use**
print(FIRInstanceID.instanceID().token()!)
if there was no connection established earlier,
you can try sending the token again to server.
*/
let token = FIRInstanceID.instanceID().token()!
self.sendFCMTokenToServer(token: token)
}
}
}
For debugging, use the token obtained from FIRInstanceID.instanceID().token()!
and use firebase push-alert console with the same token in the tab> project> Cloud messaging.
