Running macOS 15.4.1, Simulator 16.0 (1042.1), various iOS devices (iPhone 16, iPad 13" M4) I log into iCloud and enable iCloud Drive. Running the Files app, I noticed that I can click on "flat" documents (PDF, JPEG, etc) and they work. However, when I click on "package" documents (e.g. represented by a directory behind the scenes), I get a normal download progress, but then an alert "The operation could not be completed. No such file or directory". This seems to happen with all package documents, e.g. Keynote documents or Reality Composer objcap documents. It does not happen on actual devices logged into the same account. I've tried completely deleting and rebuilding the simulator instances in question, with no success.

Hi all, I’m building an iOS app where I need to determine user picked files or folders using UIDocumentPickerViewController, whether the selected item is synced or managed by a cloud storage provider such as: Google Drive iCloud Drive OneDrive Dropbox or any third-party File Provider extension My intent is to detect this and optionally warn the user that the item may be subject to syncing behavior. So far, I’ve tried a few different approaches: Extended Attributes (listxattr / getxattr) While this does not give reliable outcome. Heuristically search for keywords like 'Drive', 'GoogleDrive' etc But this is also not reliable. Question Is there any possible reliable and documented way to detect programmatically if a file/folder is cloud-synced or managed by a File Provider from within a regular iOS app (not an extension), especially for: Google Drive OneDrive Dropbox iCloud Other third-party providers? Also, is there any recommended fallback strategy for iOS versions prior to 17 where NSFileProviderManager may have limitations? Any input from Apple engineers or those who have tackled this would be hugely appreciated! Thanks in advance 🙌

I'm a first time developer for Swift, (getting on a bit!) but after programming in VB back in the late 90s I wanted to write an app for iPhone. I think I might have gone about it the wrong way, but I've got an app that works great on my iPhone or works great on my iPad. It saves the data persistently on device, but, no matter how much I try, what I read and even resorting to AI (ChatGPT & Gemini) I still can't get it to save the data on iCloud to synchronise between the two and work across the devices. I think it must be something pretty fundamental I'm doing (or more likely not doing) that is causing the issue. I'm setting up my signing and capabilities as per the available instructions but I always get a fatal error. I think it might be something to do with making fields optional, but at this point I'm second guessing myself and feeling a complete failure. Any advice or pointers would be really gratefully appreciated. I like my app and would like eventually to get it on the App Store but at this point in time I feel it should be on the failed projects heap! I've even tried a new Xcode project for iOS and asking it to use SwiftData and CloudKit - the default project should work - right? But it absolutely doesn't for me. Please send help!!

I'm working on implementing file moving with NSFileCoordinator. I'm using the slightly newer asynchronous API with the NSFileAccessIntents. My question is, how do I go about notifying the coordinator about the item move? Should I simply create a new instance in the asynchronous block? Or does it need to be the same coordinator instance? let writeQueue = OperationQueue() public func saveAndMove(data: String, to newURL: URL) { let oldURL = presentedItemURL! let sourceIntent = NSFileAccessIntent.writingIntent(with: oldURL, options: .forMoving) let destinationIntent = NSFileAccessIntent.writingIntent(with: newURL, options: .forReplacing) let coordinator = NSFileCoordinator() coordinator.coordinate(with: [sourceIntent, destinationIntent], queue: writeQueue) { error in if let error { return } do { // ERROR: Can't access NSFileCoordinator because it is not Sendable (Swift 6) coordinator.item(at: oldURL, willMoveTo: newURL) try FileManager.default.moveItem(at: oldURL, to: newURL) coordinator.item(at: oldURL, didMoveTo: newURL) } catch { print("Failed to move to \(newURL)") } } }

The problem is that the iCloud Drive directory of my app does not appear in my iCloud Drive in Finder despite the (I think) correct settings in my info.plist file (see below). In Terminal, I can see the folder and it also contains .txt files. What can I do to make the folder visible in Finder and the Files app? <key>NSUbiquitousContainers</key> <dict> <key>iCloud.vmk.NewsSwiper</key> <dict> <key>NSUbiquitousContainerIsDocumentScopePublic</key> <true/> <key>NSUbiquitousContainerName</key> <string>RSS-Filter</string> <key>NSUbiquitousContainerIdentifier</key> <string>iCloud.vmk.NewsSwiper</string> <key>NSUbiquitousContainerSupportedFolderLevels</key> <string>Any</string> </dict> </dict>

Hi all I have two mystic issues with saving and fetching data to and from iCloud. Both repro only after first launch of an app. 1. [GKLocalPlayer fetchSavedGamesWithCompletionHandler:] After first attempt I can see 0 saved games (but i know that there is at least one saved game) and there is no any error. In case if I try fetch one more time (without any additional actions) even immediately after first attempt I receive saved games correctly (not 0) 2. [GKLocalPlayer saveGameData: withName: completionHandler:] After first attempt I can see error The requested operation could not be completed because local player has not been authenticated. In case if I try save one more time (without any additional actions) even immediately after first attempt I can save data successfully without any error I found the same issue in StackOverflow, but there are no fixes...

I'm getting an error when trying to login to iCloud.com. This only happens on my Windows 11 pc and not on my iPhone. I get the 2FA code on my phone, but on my pc it displays only the error. I also have checked the system status page from apple and everything is green there, so i have no idea what is happening.

Has anyone had the issue where you try to sign in and you have to repetitively put you log in in to finally take? When it does take you set up your syncing options but your photo's, Files and everything never sync. I've updated all my system files on my computer. I even did a clean install of my windows operating system and installed it and it's doing the same thing. Any suggestions?

I am trying to read and write a text file from an App written in Swift in XCode directly to the "iCloud Drive" folder in Files on the iPhone. The app worked readlly reading and writing to the Documents folder in the App container, and then readily to the "On My iPhone" folder in Files after adding 2 lines to the plist that I found in a search online. But I have been unable to get to the iCloud Drive folder. I found an item called "Enabling Document Storage in iCloud Drive" in "iCloud Design Guide" with additional plist entries that states "These settings allow iCloud Drive to provide public access to the files stored in your app’s container": NSUbiquitousContainers iCloud.com.example.MyApp NSUbiquitousContainerIsDocumentScopePublic NSUbiquitousContainerSupportedFolderLevels Any NSUbiquitousContainerName MyApp I think I changed the MyApp items appropriately. I have enabled iCloud in my App and the XCode General, and Signing entries. But this does not work. There are no error messages and no "Steps" shown in the "Capabilities" entry in Xcode. A little help? :-)

In Apple Numbers and similar apps, a user can save a document to iCloud Drive, and collaborate with other users. From what I can gather, it seems to use two mechanisms: the document as a whole is synced via iCloud Drive, but when a collaboration is started, it seems to use CloudKit records to do live updates. I am working on a similar app, that saves documents to iCloud Drive (on Mac, iPad, and iPhone). Currently it only syncs via iCloud Drive, re-reading the entire (often large) document when a remote change occurs. This can lead to a delay of several seconds (up to a minute) for the document to be saved, synced to the server, synced from the server, and re-read. I'm working on adding a "live sync", i.e. the ability to see changes in as near to real-time as feasible, like in Apple's apps. The document as a whole will remain syncing via iCloud Drive. My thought is to add a CloudKit CKRecord-based sync when two or more users are collaborating on a document, recording only the diffs for quick updates. The app would no longer re-read the entire document when iCloud Drive updates it while in use, and would instead read the CloudKit records and apply those changes. This should be much faster. Is my understanding of how Apple does it correct? Does my proposed approach seem sensible? Has anyone else implemented something like this, with iCloud Drive-based documents and a CloudKit live sync? In terms of technologies, I see that Apple now has a Shared with You framework, with the ability to use a NSItemProvider to start the collaboration. Which raises the question, should I use the iCloud Drive document for the collaboration (as I do now), or the CloudKit CKShare diff? I think I'd have to use the document as a whole, both so it works with the Send Copy option, and so a user that doesn't have the document gets it when using Collaborate. Once the collaboration is underway, I'd want to start the CloudKit channel. So I guess I'd save the CKShare to the server, get its URL, and save that in the document, so another user can read that URL as part of their initial load of the document from iCloud Drive? Once two (or more) users have the document via iCloud Drive, and the CKShare via the embedded URL, I should be able to do further live-sync updates via CloudKit. If a user closes the document and re-opens it, they'd get the updates via iCloud Drive, so no need to apply any updates from before the document was opened. Does all this sound reasonable, or am I overlooking some gotcha? I'd appreciate any advice from people who have experience with this kind of syncing.

I am unable to download file from iCloud Documents from my swift project. I was able to successfully upload the file to iCloud Documents but now when I try to download same file at the uploaded path. It is giving me error that I don't have permission to view the file. Please find exact error below. [ERROR] couldn't fetch remote operation IDs: NSError: Cocoa 257 "The file couldn’t be opened because you don’t have permission to view it." "Error returned from daemon: Error Domain=com.apple.accounts Code=7 "(null)""

My app uses UIDocumentPickerViewController to display image files that are saved on iCloud Drive. In previous versions of iOS the user could long press on an image file and an option to Delete was shown. This no longer seems to be the case in iOS 18. Is there a way to allow users to delete files when using a UIDocumentPickerViewController?

Hi, I'm working on integrating iCloud Drive functionality into my app. I noticed that the folder for my app appears under /Users/USERNAME/Library/Mobile Documents/MY_CONTAINER, but it doesn't show up in iCloud Drive. Am I missing a step in the setup or configuration? Any guidance would be appreciated! Thanks!

I got 16 pro max and did restore from iCloud. all system files are downloaded but apps are getting stack at roughly 60% tried to delete the app and download via AppStore hard reset changing language go on different wifi and use mobile data as well Any idea how to fix?

Since iOS 18, I have gotten user reports that the UIDocumentPickerViewController directoryURL is no longer opening the correct folder. Instead it is just loading the root directory of the Files app/iCloud files. Did something change in iOS 18 that I need to account for? Not all users are having this issue, but some are and they are frustrated because a major feature of my app was to allow users to save files at the ubiquityURL. I use the following to get the path: NSURL *rootDirectory = [[[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil] URLByAppendingPathComponent:[NSString stringWithFormat:@"Documents/Photos/%@", folderName]]; Is there something that I need to do differently now in iOS 18 to prevent this from happening?

Hi, With UIDocumentPickerViewController, there is a directoryURL property that says we can use to 'specify the starting directory for the document picker'. But it's not clear how to get the directory of a folder in iCloud Drive / Files app. How can I get the 'root' directory for a user's iCloud Drive or Dropbox folder, or the Downloads folder on their device, that I could pass to this directoryURL to make it easier for the user to pick their files? Thanks.

I'm using SwiftData, and I'm using iCloud's CloudKit feature to back up my data. The problem here is that once you start backing up your data, you can't erase it completely. Even if the user adds 4 data and erases 4 again, I'm using about 2.5kb. I don't know how the user using the app will accept this. I'm trying to provide the user with the ability to erase data at once, what should I do??

struct ModelContainerSetup { static let shared = ModelContainerSetup() private static let containerIdentifier = "iCloud.Journal" func setupModelContainer() -> ModelContainer { let schema = Schema([User.self]) let modelConfiguration = ModelConfiguration( schema: schema, isStoredInMemoryOnly: false, cloudKitDatabase: .private(Self.containerIdentifier) ) do { return try ModelContainer(for: schema, configurations: [modelConfiguration]) } catch { fatalError("Could not create ModelContainer: \(error)") } } **Expected Behavior: ** When CloudKit storage is full, the app should continue functioning with local storage Data should persist locally even if cloud sync fails Sync should resume when storage becomes available **Actual Behavior: ** ModelContainer initialization fails completely Local data also stops getting saved **Environment: ** iOS 17.0+ SwiftData Private CloudKit database Ideal Behaviour: When iCloud fails, the data should still be saved locally. I do not want to have two different containers so that I can maintain data consistency.

Bonjour, a chaque installation de swift playgrounds sur ipad, icloud empeche la sauvegarde et empeche donc d’ouvrir les app. sur icloud drive les fichiers sont present mais a zero ko. par contre les fichiers playgroundsbook fonctionnent. la premiere solution que j’ai ***** etait de desactivé la sauvegarde icloud et ca a fonctionné en local. mais comme je veux mes fichiers sur le icloud drive j’ai tenté une autre approche. j’ai tenté de copié mes fichiers en local sur icloud drive ca ne fonctionne pas. puis j’ai juste fait un drag/drop de fichier app vers le playgrounds. l’app s’ouvre mais n’est pas sauvegardé dans icloud drive. par contre les modifs sont bien enregistrées. enfin j’ai refait la meme approche, une fois l’app ouverte dans playgrounds je l’ai partagé puis enregistré dans icloud. cette fois ci le fichier est pris en compte et fonctionne.

As the title says, I logged in to iCloud on my simulator on my mac mini m2 and turned on icloud sync. My health data is in iCloud but it wont load in. When I go to documents for example I can see documents that I have loaded so I know something is working right. I have tried clicking Feature -> Trigger iCloud sync with no luck. I have tried logging out and logging back in, no luck. I have tried Restarting the simulator with no luck. The app I am building uses health data and there is no other way to get health data (heart rate, workouts, sleep) in the simulator. Please help, Thank you
