Answer 1

The token you are using in Pusher doesn't look right. My tokens for remote notifications look like this.

I was just testing silent pushes, but the token would look similar for regular alerts. Here is the code I use to grab the token. My guess is that you are pushing a bad token up to FCM.

fileprivate func convertHexDataToString(_ data: Data) -> String {
    var string: String = ""
    for i in 0..<data.count {
        string += String(format: "%02.2hhx", data[i] as CVarArg)
    }
    return string
}

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let tokenString = convertHexDataToString(deviceToken)
    #if DEBUG
    print("APN sandbox token: '\(tokenString)'")
    Messaging.messaging().setAPNSToken(deviceToken, type: .sandbox)
    #else
    print("APN prod token: '\(tokenString)'")
    Messaging.messaging().setAPNSToken(deviceToken, type: .prod)
    #endif        
}
