如何使用先前保存的coreData加载TextEditor

guard let modelURL = Bundle.main.url(forResource: "YourDataModelName", withExtension: "momd") else {
    fatalError("Error loading data model from bundle")
}

guard let mom = NSManagedObjectModel(contentsOf: modelURL) else {
    fatalError("Error initializing mom from: \(modelURL)")
}

let container = NSPersistentContainer(name: "YourDataModelName", managedObjectModel: mom)

container.loadPersistentStores(completionHandler: { (storeDescription, error) in
    if let error = error as NSError? {
        fatalError("Error loading persistent stores: \(error)")
    }
})

let fetchRequest: NSFetchRequest<TextEditor> = TextEditor.fetchRequest()
// 添加适当的NSPredicate来过滤结果，如果需要的话

let fetchedResultsController = NSFetchedResultsController(fetchRequest: fetchRequest,
                                                          managedObjectContext: container.viewContext,
                                                          sectionNameKeyPath: nil,
                                                          cacheName: nil)
fetchedResultsController.delegate = self // 如果需要，实现合适的代理方法来响应结果更改

do {
    try fetchedResultsController.performFetch()
    if let textEditors = fetchedResultsController.fetchedObjects {
        for textEditor in textEditors {
            // 处理每个文本编辑对象
        }
    }
} catch {
    // 处理错误
}
