I solve the issue by this way if anyone face the same

var messageIndex: Results<MessageRealm>!
let realm = try! Realm()
let mssagesRealm = realm.objects(UsersRealm.self).filter("sender = %@", userTitleName)

   for sub in mssagesRealm {
       messageIndex = sub.msgs.sorted(byKeyPath: "timeStamp")
      }
