Here is the solution,

First Upload the necessary certificates in Firebase Console Then in your app enable Push Notifications and Background Modes -> Remote Notifications

After that in App Delegate use the code below(I specify the tricky line) :

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    registerForPushNotifications(application)
    // Override point for customization after application launch.
    // Use Firebase library to configure APIs
    FIRApp.configure()
    return true
}

func registerForPushNotifications(application: UIApplication) {
    let notificationSettings = UIUserNotificationSettings(
        forTypes: [.Badge, .Sound, .Alert], categories: nil)
    application.registerUserNotificationSettings(notificationSettings)
}

func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
    if notificationSettings.types != .None {
        application.registerForRemoteNotifications()
    }
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    let tokenChars = UnsafePointer(deviceToken.bytes)
    var tokenString = ""

    for i in 0..
