I'm struggling with writing to an iCloud file. I want my IOS app to open files on the iCloud driver. I get the above error upon return from fopen(filename, "w"). Further, the container name (iCloud.TrackInstructor) appears in red under the iCloud stanza of the Signings & Capabilities page. I can see my container under the CloudKit page of my Apple Developer account. However, below, it states: Error loading container details. Also in red. FWIW, my app is trying to open: /private/var/mobile/Library/Mobile%20Documents/iCloud~TrackInstructor/Documents/nav_detailed_file_20220719_111330.csv I have IOS 15.5 and Xcode 13.4.1. I'm struggling. Help or ideas are appreciated.

I am wondering if Apple allows us to get access to iCloud Mail inbox and read user's messages in iOS application?  I did a lot of research but couldn't find a concrete answer.  For example, on Google, this is possible by using OAuth.

This has been a bug for a while now on Mac OS. When you sync your desktop/documents folders with iCloud at random moments it gets stuck and never finish uploading. The folder says "waiting to upload" indefinitely. I notice it happens more often when you do a git commit on a folder that is synced with iCloud. Are there any work around for that?

I believe that if I rename a file, I'm supposed to do that inside a coordinated write on the parent directory - right? So say I have a file /path/to/folder/f1 and I want to rename it (in the same directory) as /path/to/folder/f2. I do a coordinated write (with the forMoving option) on the directory /path/to/folder. That passes me a possibly different path to the directory, right? Say I get /path/to/different. Question: what rename should I actually do? Do I need to construct from and to paths based on the different path that is passed to the accessor? I.e. do I rename from /path/to/folder/f1 to /path/to/folder/f2 or rename from /path/to/different/f1 to /path/to/different/f2 or some other combination? Do NSFileManager's renaming methods do anything special in this regard? Can I use e.g. std::filesystem::rename()? I am interested in both local documents that are visible e.g. in the Files app, and iCloud Drive documents, if that makes any difference. Thanks!

Dear Experts, Is there a way to limit an NSMetadataQuery to one iCloud container, in an app with more than one? It seems to me that setting the scope to NSMetadataQueryUbiquitousDocumentsScope will probably return either the contents of the first (default) container, or all containers Is there something I can put in the predicate? Maybe I have to try to match URLs that start-with the container's own URL?

I'm struggling to find a way to monitor the progress (in percent, or bytes) of a download from iCloud Drive. I.e. files outside of the app's ubiquitous document folder. Our app provides a directory browser (which is accessed using a security scoped bookmark granted by the user). In this browser we want to enable users to download files from iCloud analogous to the user experience provided in Files.app. It seems that NSMetaDataQuery would be the right way to go nowadays. However i don't get any results for queries outside of my own app container. I suppose that's a permission problem? Luckily we can get most of what we need using url's resource values. Also initiating and canceling a download works using NSFileManager. However i found now suitable way of determining a download's progress. NSURLUbiquitousItemPercentDownloadedKey is deprecated and doesn't give any results. Did i overlook something? Is there a way to get NSMetaDataQuery working with security scoped bookmarks to folders?

I have an issue on importing files into my app when selected by the user through UIDocumentPickerViewController. The error I get is: Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied". I'm testing on iPhone 11 with iOS 13.5.1. This is my implementation: func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]){                  urls.forEach { (url) in                          let access = url.startAccessingSecurityScopedResource()             var error: NSError? = nil             NSFileCoordinator().coordinate(readingItemAt: url, error: &error) { (coorURL) in             do{                     let gZippedData = try Data(contentsOf: url)                     print(gZippedData)                     if access{                         url.stopAccessingSecurityScopedResource()                     }                 }catch{                     print(error.localizedDescription)                 }                     }                 }             }         }     } The value of access is true. why I can't access the file? what am I missing? Thank you for your help.

I posted this in the user forums but got no response as I suspect it's too low-level for the discussions there. I think this is a relevant developer issue, even though I am only interested in this from a user perpsective. Perhaps someone can confirm my reasoning (and the resulting potential for errors/bugs when syncing between Mac and Windows iCloud Drive)...----After some investigation of log files for iCloud for Windows (Drive specifically) (latest version - 10.7.0.7 / 2.0.74.23) , I think I've discovered a major reason why there are so many syncing issues with iCloud for Windows.My theory is:1) iCloud for Windows is built on top of the OneDrive technology. https://www.howtogeek.com/fyi/daily-news-roundup-icloud-for-windows-powered-by-onedrive-tech/2) OneDrive technology limits the file path length to 216 characters (or thereabouts). You can verify this yourself by trying to create a folder path depth over 216 characters in length using OneDrive. See this article for some more information: http://www.purgeie.com/shareprep/maxlength.htm3) Mac OSX filing system and iCloud (for Mac), don't have the same folder path restriction (well as far as I can see it's somewhere around 1024 characters - https://stackoverflow.com/questions/7140575/mac-os-x-lion-what-is-the-max-path-length).4) So files that are successfully uploaded to iCloud from a Mac, will fail to download on to Windows 10 if they exceed the OneDrive folder path length of ~250.Checking the log files of iCloud for Windows I get errors such asERROR BRC::LocalContainer::CreateNewFilePlaceholder Error creating unique file path for itemIDERROR BRC::LocalContainer::ApplyChangesForLiveFile Failed to create placeholder forWARN BRC::LocalContainer::UpdateUnappliedRankRetryWithEtag com.apple.CloudDocs:__defaultOwner__: Will retry applying itemERROR BRC::LocalContainer::ApplyChangesSchedule Apply failed for itemThe filename, directory name, or volume label syntax is incorrect.5) This then causes iCloud for Windows to constantly retry creating placeholders and downloading, and constantly failing....WARN BRC::LocalContainer::UpdateUnappliedRankRetryWithEtag com.apple.CloudDocs:__defaultOwner__: Will retry applying item in 30 seconds (retryCount = 0)ERROR CKD::MMCS::GetErrorWithMMCSError Error Domain=com.apple.mmcs Code=16 "Last 4 requests failed with a network error. Retry after 16 seconds" UserInfo= {NSLocalizedDescription=Last 4 requests failed with a network error. Retry after 16 seconds,----------------------I don't see anyway easy way around this issue as the two OS are fundamentally incompatible in terms of filing system limits (note Windows 10 can have a larger limit using registry, but it appears OneDrive has the lower limit, which is the bottleneck).So the only way I can see is to reorganise all folders/files that are synced to iCloud to be under the ~250 character limit. And there is no easy way to check this while working normally in iCloud (on Mac side) - so you could unintentionally create a folder path depth that exceeds the OneDrive limit. It will work on the Mac side, but when using Windows it will fail.I haven't thoroughly tested this theory, but after waiting days for my iCloud for Windows to sync, I decided to dig a little deeper and found the above information (and log files).I have quite a deep structure to my filing, but I doubt I'm a complete edge case (!). Perhaps someone out there can verify these limits and symptoms. The log files for iCloud for Windows can be found atC:\Users\USERNAME\AppData\Local\Packages\AppleInc.iCloud_HASHCODE\LocalCache\Local\Logs

I'm attempting to create a Swift/SwiftUI app that will run on iOS/iPadOS that uses CloudKit to syncronize data between devices. I have created the App in Xcode.In the Apps Signing & Capabilities tab, I have:- Ensured that the Bundle Identifier is valid- Added the iCloud capability - Created the Container and checked it - Validated that the Container was created in the CloudKit Dashbaord- Added the Backgrouind Modes capability - Checked the Remote notifications optionI have modified/validated AppDelegate.swift:- Validated that it is using NSPersistentCloudKitContainer- Added container.viewContext.automaticallyMergesChangesFromParent to true- Added container.viewContext.mergePolicy to NSMergeByPropertyObjectTrumpMergePolicyWhen I load the App, I get a series of errors reported related to CloudKit NSCloudKitMirroringExportRequest. These errors are shown below. I am able to create records, but can see they are only stored locally and do not get synced to the CloudKit Dashboard - interestingly enough, the schema has been created in CloudKit Dashboard - so I know some level of connection has been made.I appreciate any insight that someone can give me to resolve this and allow my data to sync properly.CoreData: CloudKit: CoreData+CloudKit: -[NSCloudKitMirroringDelegate _scheduleAutomatedExportWithLabel:activity:completionHandler:]_block_invoke(2174): <NSCloudKitMirroringDelegate: 0x600003ef0c60> - Finished automatic export - ExportActivity - with result: <NSCloudKitMirroringResult: 0x60000096cc40> success: 0 madeChanges: 0 error: Error Domain=NSCocoaErrorDomain Code=134417 "Request '<NSCloudKitMirroringExportRequest: 0x6000007545a0> B79831CF-9C04-4BB0-90B7-974EB38D2A25' was cancelled because there is already a pending request of type 'NSCloudKitMirroringExportRequest'."

I'm using NSMetadataQuery and NotificationCenter, to perform file downloading from iCloud. Construct NSMetadataQuery with predicate NSPredicate(format: "%K == %@", NSMetadataItemFSNameKey, filename) Observe NSMetadataQueryDidUpdate & NSMetadataQueryDidFinishGathering using NotificationCenter. Check file status NSMetadataUbiquitousItemDownloadingStatusKey. If the file is up-to-date, copy the file to destination directory, and jump to step 6. Perform FileManager.default.startDownloadingUbiquitousItem Receive file downloading status in NSMetadataQueryDidUpdate callback. If the file is up-to-date, copy the file to destination directory, and jump to step 6. Perform cleanup by removing all observers. If file is not available in iCloud, no notification received. We wish, even if the file doesn't exist, we will still be notified, so that we have chance to perform cleanup (step 6) Here's the code snippet to perform iCloud download.

I am attempting to erase everything from my old iPhone after I have transferred all my content and settings to the new one. However, the process seems to get stuck when it tries to “upload data” to iCloud and when I press the “skip backup” button, it still remains frozen (whether or not I press skip backup it will not pass this stage of the erase process). I have tried force restarting my phone and that didn’t seem to work. Does anyone have advice or a suggestion?

I have a macOS app that synchronizes some files in the app's iCloud container, outside the Documents folder. Changes to these files are monitored with a NSMetadataQuery using a search scope of NSMetadataQueryUbiquitousDataScope. The NSMetadataQuery instance uses an operation queue for notifications and I'm calling startQuery on the instance's operation queue. As of macOS 12.3, for a subset of my users, the NSMetadataQueryDidFinishGatheringNotification notification is never sent after starting the query. The NSMetadataQueryDidStartGatheringNotification and NSMetadataQueryGatheringProgressNotification notifications are posted. For those affected who have multiple Macs, each of their Macs seems to be affected by this, as if it is a problem specific to the iCloud container for my app, for that user. I'm unable to reproduce the issue on my personal machine. Has anyone else noticed this behavior since macOS 12.3 was released?

Hey, I wanted to ask if it is possible to download all the content of iCloud automatically (or just the images). Is there any way to automatically request your data or something like that?

Hi, So after updating my mac to Catalina few week ago, the system preferences was keeping asking to "accept terms and condition" but for some reason I could not open the tab to accept them. Since I could not remember the password,I logged off my apple ID and I re-set the password. Everything was absolutely unchanged. Suddenly after log back in, all the folders and document I had in my desktop (that technically were in iCloud) disappeared for 20min to then reappear suddenly without me doing nothing. Today I was open the folder in my desktop searching for a document and it is gone, it is not there anymore. I went to iCloud.com and ALL the files there were from either mid 12/2021 or early 01/2022. that's it. lost 5 month of work. If I open one of the file that I opened and modified yesterday to restore a more recent version, it just gives me the one from January and none of these form yesterday. I did try to go on iCloud and restore the file but it says "no file to restore" and also there was no file in "deleted". Anyone can help? Camilla

Hi,I have 2 iOS apps with which I tested iCloud Drive.With the frst one I didn't had any trouble.I'm able to use the iCloud Drive and files that I store in the ubiquituos container are transferred to the cloudand I can see the Apps folder and contents in Finder on my iMac.Now the strange thing is that with the 2nd app I get problems although I have setup everything exactly the same.The only difference that I can see is that during the initial run of App2 with iCloud entitlements enabled I had forgottento add the &lt;key&gt;NSUbiquitousContainers&lt;/key&gt; &lt;dict&gt; &lt;key&gt;iCloud.com.***.app2&lt;/key&gt; &lt;dict&gt; &lt;key&gt;NSUbiquitousContainerIsDocumentScopePublic&lt;/key&gt; &lt;true/&gt; &lt;key&gt;NSUbiquitousContainerName&lt;/key&gt; &lt;string&gt;App2&lt;/string&gt; &lt;key&gt;NSUbiquitousContainerSupportedFolderLevels&lt;/key&gt; &lt;string&gt;Any&lt;/string&gt; &lt;/dict&gt; &lt;/dict&gt;in the info-plist file.I get the feeling that this screwed app the iCloud for this app and even if I now set this up correctly it refuses to work.Any one experiencing a similar issue?Or is there any way to reset the iCloud for an app completely and start over again?One more thing: when using brctl I can see that items are sent/retrieved from the iCloud and they are stored in theiCloud Drive folder on my Mac. But they are not visible in Finder.

Hi,I've got my CloudKit records with created and modifed setup to be sortable and queryable but I'm having a hard time constructing a CloudKit.js query that will use those values.This: var query = { recordType: "MyRecord", sortBy: [{ fieldName: 'created' }] };This doesn't work, I get this error:Unknown field 'CKFieldName{_name='created'}I also tried 'createdDate', 'modified', 'modificationDate' and all give the same error. What's the magic?
