如何设置NSFetchedResultsController,在Swift中传入实体名称

在Swift中,当您声明如下所示的NSFetchedResultsController时,必须声明 NSFetchedResultsController 将返回,例如。 NSFetchedResultsController<Quote> :

fileprivate lazy var fetchedResultsController: NSFetchedResultsController<Quote> = {
    // Create Fetch Request
    let fetchRequest: NSFetchRequest<Quote> = Quote.fetchRequest()

    // Configure Fetch Request
    fetchRequest.sortDescriptors = [NSSortDescriptor(key: "name", ascending: true)]

    // Create Fetched Results Controller
    let fetchedResultsController = NSFetchedResultsController(fetchRequest: fetchRequest, managedObjectContext: self.persistentContainer.viewContext, sectionNameKeyPath: nil, cacheName: nil)

    // Configure Fetched Results Controller
    fetchedResultsController.delegate = self

    return fetchedResultsController
}()

如果我想对两个不同的核心数据实体使用相同的tableview,并将实体的值注入 UITableViewController 作为 String 或 Enum 我将如何重写代码以反映注入的值?
