我想在 cloudkit 上的值更改时收到通知

这是我的代码：

let now = Date()
    let timeInterval:TimeInterval = now.timeIntervalSince1970
    let timeStamp = Int(timeInterval)
let publicDB = CKContainer.default().publicCloudDatabase
    let bookID = CKRecord.ID(recordName: "\(timeStamp)")
    let book = CKRecord(recordType: "Book", recordID: bookID)
