如何使用SwiftUI从CloudKit检索数据

import CloudKit

let recordType = "YourRecordType"
let predicate = NSPredicate(value: true)
let query = CKQuery(recordType: recordType, predicate: predicate)

let container = CKContainer.default()
let database = container.publicCloudDatabase

database.perform(query, inZoneWith: nil) { (records, error) in
    if let error = error {
        print("查询失败：\(error.localizedDescription)")
    } else if let records = records {
        // 处理查询结果
    }
}

for record in records {
    if let name = record["Name"] as? String {
        print("记录名称：\(name)")
    }
    // 提取其他字段数据
}
