I know you've stumbled across this question before; several times in fact. But I have followed EVERY suggestion provided to me here, here, and even here.
(Written in Swift 3, running on Xcode 8.1)
Yes, my PUSH NOTIFICATIONS in Capabilities are on. And even my Background Modes Remote Capabilities is on - I've tried toggling the FirebaseAppDelegateProxy On and Off, checked the certificates (why, yes, it is pointing to the correct App bundle), moved the
application.registerForRemoteNotifications()
Cried, consumed copious amounts of sugar, prayed to God and then what ever other related deities I could think of, and still - naught.
It could just be a screaming need for a second set of eyes, but any ideas?

import UserNotifications

let authOptions : UNAuthorizationOptions = [.alert, .badge, .sound]

completionHandler: {_,_ in })
// For iOS 10 display notification (sent via APNS)

} else {

}
func applicationDidEnterBackground(_ application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
func applicationWillEnterForeground(_ application: UIApplication) {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(_ application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
func applicationWillTerminate(_ application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
// If you are receiving a notification message while your app is in the background,
// this callback will not be fired till the user taps on the notification launching the application.
// TODO: Handle data of notification
// Print message ID.
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
// Print full message.
print(userInfo)
}
private func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
// let tokenChars = deviceToken.bytes
var tokenString = ""
for i in 0..<deviceToken.length {
tokenString += String(format: "%02.2hhx", arguments: [[deviceToken.bytes as! CVarArg][i]])
}
FIRInstanceID.instanceID().setAPNSToken(deviceToken as Data, type: FIRInstanceIDAPNSTokenType.unknown)
print("tokenString: \(tokenString)")
}
}
And here are the extensions...
import Foundation
import UserNotifications
import FirebaseMessaging
@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
// Receive displayed notifications for iOS 10 devices.
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
// Print message ID.
print("Message ID: \(userInfo["gcm.message_id"]!)")
// Print full message.
print("%@", userInfo)
}
}
extension AppDelegate : FIRMessagingDelegate {
// Receive data message on iOS 10 devices.
func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
print("%@", remoteMessage.appData)
}
}
Tokens are logging into the console, FCM is connected, Cloud Messaging is holding my certificates... the only possible hint I MAY have is that Firebase Console doesn't count the one device it is sending a message to as being 'Sent'.
But the console looks fine.

... but the message is logging just fine in my console. In fact, there are not outcrying errors at all!
sigh
My phone is not getting foreground, background or any sort of notification from the app - there's nothing. Zip. Zilch. Nada. Just the breaking sounds of my heart.
My iPhone is currently on 9.3.5. If that helps any.
Any help would be greatly appreciated - or suggestions for alternative push notification systems...
Figured it out. p.s. im using Swift 3 syntax, you are missing the completionhandler in your willPresent method
