带有Swift ToDo列表应用程序的CloudKit -如何使用iCloud公共和私有数据库信息填充表视图

import CloudKit

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // 设置CloudKit容器
    CKContainer.default().accountStatus { (accountStatus, error) in
        if accountStatus == .available {
            // 可以使用CloudKit
        } else {
            // 无法使用CloudKit
        }
    }
    return true
}

import CloudKit

class TaskManager {
    let container = CKContainer.default()
    let privateDatabase = container.privateCloudDatabase
    
    func fetchTasks(completion: @escaping ([CKRecord]?, Error?) -> Void) {
        let query = CKQuery(recordType: "Task", predicate: NSPredicate(value: true))
        privateDatabase.perform(query, inZoneWith: nil, completionHandler: completion)
    }
    
    func saveTask(_ task: CKRecord, completion: @escaping (Error?) -> Void) {
        privateDatabase.save(task, completionHandler: completion)
    }
}

import UIKit
import CloudKit

class ViewController: UIViewController, UITableViewDataSource {
    @IBOutlet weak var tableView: UITableView!
    
    var tasks: [CKRecord] = []
    let taskManager = TaskManager()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        tableView.dataSource = self
        
        taskManager.fetchTasks { [weak self] (records, error) in
            if let error = error {
                print("Error fetching tasks: \(error.localizedDescription)")
            } else if let records = records {
                self?.tasks = records
                DispatchQueue.main.async {
                    self?.tableView.reloadData()
                }
            }
        }
    }
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return tasks.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "TaskCell", for: indexPath)
        let task = tasks[indexPath.row]
        cell.textLabel?.text = task["title"] as? String
        return cell
    }
}
