Swift FCM send notification to specific token Not Working at Background - ios

Question

I working now on the notification system for my app.
I used This func to send Notification to specific token device:
func sendPushNotification(to token: String, title: String, body: String) {
let urlString = "https://fcm.googleapis.com/fcm/send"
let url = NSURL(string: urlString)!
let paramString: [String : Any] = ["to" : token,
"content-available": 1,
"priority":"high",
"notification" : ["title" : title, "body" : body],
"data" : ["user" : "test_id"]
]
let request = NSMutableURLRequest(url: url as URL)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject:paramString, options: [.prettyPrinted])
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.setValue("key=My Key", forHTTPHeaderField: "Authorization")
let task = URLSession.shared.dataTask(with: request as URLRequest) { (data, response, error) in
do {
if let jsonData = data {
if let jsonDataDict = try JSONSerialization.jsonObject(with: jsonData, options: JSONSerialization.ReadingOptions.allowFragments) as? [String: AnyObject] {
NSLog("Received data:\n\(jsonDataDict))")
}
}
} catch let err as NSError {
print("Error Notification: \(err.debugDescription)")
}
}
task.resume()
}
I got the notification like I expected but when the app at background I get the Notification alert but 'didReceiveRemoteNotification' not called even when I added ' "content-available": 1 ' to my Notification params.

Thanks.
