iOS Firebase push notifications not appearing

Question

I've set up push notifications according to this walkthrough: https://www.appcoda.com/firebase-push-notifications/

But when I send a test message from Firebase, it doesn't show up. I followed all the steps, I have valid certificates:

Provisioning Profile set up for push notifications:

Under my App ID it shows that notifications are enabled:

And I have the certificate uploaded to Firebase:

And in my AppDelegate didFinishLaunchingWithOptions:

    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
        FIRMessaging.messaging().remoteMessageDelegate = self
    } else {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)
    }


    application.registerForRemoteNotifications()

Along with the Firebase callback method in AppDelegate:

func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
    print(remoteMessage.appData)
}

And obviously I have imported:

import UserNotifications
import FirebaseInstanceID
import FirebaseMessaging

I'm not sure why the push notifications are not working, it seems like everything is in place. The only thing out of the ordinary I did was remove the entitlements from Target -> Code Signing, as it was giving me an invalid entitlements error when I tried to run the app. Now that it's removed, the app is running fine. I do have an open question about that separate issue but for now I'll assume that's not the cause of my problems here.

And just to confirm, I don't have to re-download the Google plist after adding notifications? I was using Firebase in my project before adding notifications, so I already have one.

Thanks for any help getting the notifications working!

please remove the device from Xcode and try ur getting the push or not?. and some times in development mode did register with notification not calling. — Phani Sai, Jun 07 '17 at 15:13
Do any of you know if it's required to re-download the Google-Info.plist file after adding FirebaseMessaging/notifications? I had Firebase in my app before I tried to add notifications so I have the original plist. — KingTim, Jun 07 '17 at 15:21

Try Adding FirebaseAppDelegateProxyEnabled type "Boolean" value "NO" in your info.plist

and maybe add Messaging.messaging().shouldEstablishDirectChannel to true in your AppDelegate

Can you check in the capabilities tab if push notifications are enabled. Also, since Xcode 8 you need to add the entitlements file with aps-environment set. If you disable and enable the push notifications from capabilities you will get this file.

Please have a look at the documentation - https://developer.apple.com/library/content/documentation/Miscellaneous/Reference/EntitlementKeyReference/Chapters/EnablingLocalAndPushNotifications.html – Jasveer Singh Jun 07 '17 at 15:18
Your "Also, since Xcode 8 you need to add the entitlements file with aps-environment set." is misleading. That happens automatically if you set in the capabilities. – mfaani Jun 07 '17 at 15:19
Push notifications are enabled in capabilities. I switched it to "off", then back on again. Re-downloaded my provisioning profile, double clicked to install. Ran and now I'm getting an error "invalid entitlements" – KingTim Jun 07 '17 at 15:19
@Honey Prior to Xcode 8 entitlements file was not required. – Jasveer Singh Jun 07 '17 at 15:22
It seems to be working now, but I'm still not seeing the test notifications I'm sending out from Firebase – KingTim Jun 07 '17 at 15:23
@KingTim Can you check in you target's build settings. Code Signing Entitlements has correct file name. – Jasveer Singh Jun 07 '17 at 15:24
@KingTim for the invalid entitlements see [here](https://stackoverflow.com/questions/19581225/the-executable-gets-signed-with-invalid-entitlements-in-xcode). And just to be sure. Are you using the simulator or an actual device? Because your simulator isn't able to create a token for you. Only actual devices can do that for you – mfaani Jun 07 '17 at 15:24
@Honey I'm using my device – KingTim Jun 07 '17 at 15:26
@JasveerSingh the correct entitlements file name is there. It's giving me the invalid entitlements error again. – KingTim Jun 07 '17 at 15:26
Just FYI, when your app is in foreground you will not see any default notifications. So send the notification while app is in background mode or killed. – Jasveer Singh Jun 07 '17 at 15:28
@KingTim did you see the link I shared for invalid entitlements? Try to first solve that issue on that page. Once it's fixed come back here and try solving the issue of not receiving any notifications. – mfaani Jun 07 '17 at 15:36
@Honey, I looked and tried every solution there. I also have an open question about the same issue. I've toggled and untangled all the recommended capabilities, regenerated provisioning profiles, cleaned, restarted Xcode. No luck. – KingTim Jun 07 '17 at 15:40
@KingTim Then you should have not opened this question! Try to comment on the answers of your question and fix that issue first. I mean how do you expect it to work while you still have that issue?! You can place a bounty on it, but you can do it after 48hrs – mfaani Jun 07 '17 at 15:42
To be clear, the app runs if I simple delete the entitlements from Target -> Code Signing. Is removing the entitlements like that causing this issue with the push notifications not working? – KingTim Jun 07 '17 at 15:44
Don't remove the entitlements, try to fix the issue with entitlement. Push notifications will not work without it. – Jasveer Singh Jun 07 '17 at 15:46
I've tried every suggestion on every question on the topic I can find. If you know how to solve the entitlements issue, please don't be shy! https://stackoverflow.com/questions/44412788/invalid-entitlements-error-when-adding-push-notifications – KingTim Jun 07 '17 at 15:48
