IOS notification when Application is closed

Question

i have a ios application where to which i send remote notification when sending notification from server i am setting content -available = 1 and sound = "" When on IOS device i am using

applicaiton(didReceiveRemoteNotification:fetchCompletionHandler:)

I seeing that app reaches this method when in background but when app is closed this method is not getting called But is not getting called when application is closed

applicaiton(didReceiveRemoteNotification:fetchCompletionHandler:)

My handler in this method is

        let userInfoDic = userInfo as NSDictionary as? [String: Any]
        let cato = userInfoDic?["cato"] as? String
if cato == "message" {
            let state: UIApplicationState = UIApplication.shared.applicationState
            if state == .active{
                print("Application is Active Socket IO will Handle This")
            }else{
                let apnMessage = userInfoDic?["apnMessage"] as? [String: Any]
                if (apnMessage == nil){
                    print("Error Fetching Message")
                }else{
                let count = UserDefaults.standard.integer(forKey:"TotalUnredMessage")

                    DispatchQueue.main.async {
                        UIApplication.shared.applicationIconBadgeNumber = count + 1
                    }
                    UserDefaults.standard.set(count, forKey: "TotalUnredMessage")
          }
}

So what should i change for this methods to run even when applicaiton is closed

Thanks

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {

     if let launchOptions = launchOptions,
            let userInfo =  launchOptions[.remoteNotification] as? [AnyHashable: Any] {
            //some code here and post when needed like below
            NotificationCenter.default.post(name: NSNotification.Name("your notification name"),  object: nil)
