Ios 使用CloudKit从iCloud获取公共记录

我有以下代码用于将我的资产上载到iCloud

func uploadAsset(recordType: String, fileURL: URL) {
    let record = CKRecord(recordType: recordType)
    record["file"] = CKAsset(fileURL: fileURL)

    CKContainer.default().publicCloudDatabase.save(record) { savedRecord, error in
        if let saveError = error {
            print("An error occurred in \(saveError)")
        } else {
            print(savedRecord)
        }
    }
}

它确实有效，因为我可以进入CloudKit仪表板，实际查看记录并下载其附件

下面是该函数输出的savedRecord示例：

Optional(<CKRecord: 0x100f27f60; recordID=F6DF33CB-35DA-483A-A5B5-33542E435689:(_defaultZone:__defaultOwner__), recordChangeTag=izfmgx06, values={
    file = "<CKAsset: 0x1703e6800; path=/private/var/mobile/Containers/Shared/AppGroup/992A6367-11F5-491F-BE37-C9E4BBA865E6/voice/1487611173.95385.m4a, size=33547, UUID=D8F70489-1FF8-4CE8-99BE-390741E8136D, signature=<01a5bd3c fd9b8042 cb52cc23 3681af91 50aacaa5 97>>";
}, recordType=Voice>

我只得到如下错误：

 Error Fetching Record  Error fetching record <CKRecordID: 0x10024c6f0; recordName=6988103A-E795-441B-A115-2D044872AAAC, zoneID=_defaultZone:__defaultOwner__> from server: Record not found

获取记录时出错从服务器获取记录时出错：未找到记录

谢谢你的帮助。提前感谢！：）

错误在使用中

CKContainer.default()

在创作和拉动阶段。相反，我应该在内部使用指定的自定义容器，即

CKContainer(identifier: "iCloud.tech.jackrobson.myApp")
