英文:
iCloud file download status using ubiquitousItemDownloadingStatusKey not working
问题
如果尝试使用 resourceValues(forKeys:) 检查 URL 的下载状态，您的代码如下：
if let status = try? url.resourceValues(forKeys: [URLResourceKey.ubiquitousItemDownloadingStatusKey]) {
if status.ubiquitousItemDownloadingStatusKey == .current {
print("File download complete.")
}
}
这段代码之前可以正常工作，但现在 Xcode 报错：“Value of type 'URLResourceValues' has no member 'ubiquitousItemDownloadingStatusKey'”，并且我只能从 status 中获取一些 thumbnailDictionary。有人可以告诉我这里发生了什么吗？我是否犯了一些愚蠢的错误？
英文:
I am trying to check the download status of my url using resourceValues(forKeys:). This is my code
if let status = try? url.resourceValues(forKeys: [URLResourceKey.ubiquitousItemDownloadingStatusKey]) {
if status.ubiquitousItemDownloadingStatusKey == .current {
print("File download complete.")
}
}
This code worked before but now Xcode says "Value of type 'URLResourceValues' has no member 'ubiquitousItemDownloadingStatusKey'" and all I am able to get from status is some thumbnailDictionary. Can anyone tell me what is happening here? Am I making some silly mistake ?

你在URLResourceValues上使用了错误的属性：
if let values = try? url.resourceValues(forKeys: [.ubiquitousItemDownloadingStatusKey]),
let status = values.ubiquitousItemDownloadingStatus {
if status == .current {
print("文件下载完成。")
}
}
英文:
You're using the wrong property on URLResourceValues:
if let values = try? url.resourceValues(forKeys: [.ubiquitousItemDownloadingStatusKey]),
let status = values.ubiquitousItemDownloadingStatus {
if status == .current {
print("File download complete.")
}
}
