Firebase when receive Push Notification did not receive the popup - ios

Question

import Firebase
import FirebaseInstanceID
import FirebaseMessaging
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
registerForPushNotifications(application)
FIRApp.configure()
// Add observer for InstanceID token refresh callback.
NSNotificationCenter
.defaultCenter()
.addObserver(self, selector: #selector(AppDelegate.tokenRefreshNotificaiton),
name: kFIRInstanceIDTokenRefreshNotification, object: nil)
// Override point for customization after application launch.
return true
}
func registerForPushNotifications(application: UIApplication) {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
print("===== didReceiveRemoteNotification ===== %#", userInfo)
}
func tokenRefreshNotificaiton(notification: NSNotification) {
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.")
}
}
}
Also to done in Info.plist FirebaseAppDelegateProxyEnabled = NO
I don't know for now but I got the print(...) in didReceiveRemoteNotification but don't get the popup. I send the message from Firebase -> Console -> Notification -> Single device and copy here the token which I got from xCode Console -> func tokenRefreshNotificaiton
Get the next in console, but don't get popup
<FIRAnalytics/INFO> Firebase Analytics enabled
InstanceID token: TOKEN_ID
Connected to FCM.
===== didReceiveRemoteNotification ===== %# [notification: {
body = test;
e = 1;
}, collapse_key: com.pf.app, from: 178653764278]
Also app configurations

Answer 1

set the following code in AppDelegate.m
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
// for development
[[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeSandbox];
// for production
// [[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeProd];
}

Answer 2

I'm guessing your app is in the foreground when testing. When your app is in the foreground no visible notification is triggered, instead you receive the callback to didReceiveRemoteNotification. See the documentation for more info.
To verify, put your app in the background and try sending the push notification again.

Answer 3

I have same configuration you have and it works like AdamK said. (While in background mode, notification appears.) Also check your certificates.

Answer 4

First check with Firebase Notification Console to see if the notification is sending or not. If it is success, then the problem is in the code side; otherwise, check what error is coming in Firebase. If you receive error message as APNs missing, you need to check with development/production .p12 file in Project Setting->Cloud Messaging tab.

Answer 5

Just use this function in your app delegate sandbox for development prod for prodction
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.sandbox)
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.prod)
}

Answer 6

Are you using https://pushtry.com for test the FCM notification? then don't use because I have lots of issue with this website for testing notification some time it working and some times not. it's not giving consistence result and it may be effect in FCM flow and totally block the receiving notifications.
I recommended to use https://fcm.snayak.dev for test the notification.
