        if let todos = try? context.fetch(request)// Get data by request  { 
        // context=AppDelegate.persistentContainer.viewContext
            data[section].todos = todos
        }else{
    
            printContent(" Failed to get database data !")
        }

request.sortDescriptors = [ ] You can put more than one... In the array NSSortDescriptor(key: String, ascending: Bool) Conduct

Arrange in ascending or descending order , When pressing the first NSSortDescriptor(key: String, ascending: Bool) When the arrangement is the same, press
