Exporting the work, as expected, no problem. Import also works well, but only with files that are stored outside my app iCloud folder, that is, when I click a .txt file from mail or the iCloud public folder, I see my application in the "Import with ..."menu next to other applications. But when I click the exact same file from my app folder on iCloud, my application does not appear in the menu "Import with ...".
To clarify what I mean by saying my app folder on iCloud. The application has the function of exporting and saving certain data in iCloud with the following function:
func autoExportToIcloudDrive(_ localFileURL:URL, fileNameST:String) {
let iCloudDocumentsURL = FileManager.default.url(forUbiquityContainerIdentifier: nil)?.appendingPathComponent("Documents").appendingPathComponent("\(fileNameST).csv");
if iCloudDocumentsURL != nil {
let olderFileURL = iCloudDocumentsURL?.appendingPathComponent(fileNameST);
if FileManager.default.fileExists(atPath: olderFileURL!.path) {
self.uniFunc.deleteFileAtPath(pathUrl: olderFileURL!);
}
do {
try FileManager.default.copyItem(at: localFileURL, to: iCloudDocumentsURL!);
} catch {
let nserror = error as NSError;
fatalError("\(nserror), \(nserror.userInfo)");
}
}
}
iCloud . , "Import with ...". , "Import with ...".
, "" iCloud, - .plist?
