Onesignal push notification only accept English language ones in Swift 3 - ios

Question

I have 2 segment in onesignal panel bir EN another FR but in my app have language change and people can change app language everytime in app inside , when I send push from one signal I send by segments but i want to add appdelegate inside language section if user language is English only must be alert English pushes , if user language France only must be alert France pushes.
In my app side language selection string is
let appcurrentlanguage = prefs.value(forKey: "lang") as! String
How can I do it ?
My codes under below
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
//HERE APP LANGUAGE
let appcurrentlanguage = prefs.value(forKey: "lang") as! String
GMSServices.provideAPIKey("xxx")
OneSignal.initWithLaunchOptions(launchOptions, appId: "xxx") { (result) in
let payload = result?.notification.payload
if let additionalData = payload?.additionalData, let actionSelected = additionalData["comes"] as? String {
if actionSelected == "1" {
let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewController(withIdentifier: "ViewController") as! ViewController
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = initialViewControlleripad
self.window?.makeKeyAndVisible()
}else if actionSelected == "2" {
if let newsID = additionalData["id"] as? String {
prefs.setValue(newsID, forKeyPath: "gelenID")
prefs.synchronize()
}
if let newsType = additionalData["type"] as? String {
prefs.setValue(newsType, forKeyPath: "newsType")
prefs.synchronize()
}
}
}
}
sleep(2)
return true
}
