I was able to add new domain with 'NSFileProviderManager.add' function in Xcode past 2 months. Yesterday I created .pkg file (installer file) for distribution with 'pkgbuild' and 'productbuild' commands in terminal. I successfully install application and test it then uninstall it. However after this, In Xcode I cannot add new domain anymore. I keep getting "Error Domain=NSFileProviderErrorDomain Code=-2001 "No valid file provider found with identifier ‘’." Command that used to create .pkg file pkgbuild --root "path" --scripts "path" --identifier "same bundle identifier with app" --version 1.0 --install-location /Applications "newpkg.pkg" productbuild --synthesize --package "newpkg.pkg" Distribution.xml productbuild --distribution Distribution.xml --package-path "newpath.pkg" "newpathrelease.pkg" NOTE: When app is installed (But not running). I am able to add new domain in Xcode. After I uninstall app, I start to get same error again NOTE: I uninstall app by move it to Trash from Applications directory in finder Any suggestion about add new domain in Xcode during development? Or How to fix 'No valid file provider found with identifier' error

Hi all, i am trying to implement File Provider Extension. I have some questions about conflict resolution Same file is changed at user local and remote storage before it's synced. File has 2 different version at user local and remote storage. After trigger a new enumeration by calling signalEnumerator for the extension, I want to move user's local version to new conflicted copy (with new itemIdentifier: NSFileProviderItemIdentifier) and import remote storage version to user local (with current itemIdentifier: NSFileProviderItemIdentifier). Then users local version should uploaded to remote storage server with new conflicted copy name Any suggestion about this scenario? Or any documentation about conflict resolution

We're experimenting with FileProvider on MacOS and iOS. One of our requirements is to support downloading partial content of files. However, this looks to be supported only on MacOS as per https://developer.apple.com/documentation/fileprovider/nsfileproviderpartialcontentfetching?language=objc. Is there an alternative for NSFileProviderPartialContentFetching on iOS? If not, can you please share any standard practice on how to accomplish this on iOS? Sample code that works on MacOS - #import <FileProvider/FileProvider.h> @interface FileProviderExtension : NSObject<NSFileProviderReplicatedExtension, NSFileProviderPartialContentFetching> For iOS platform, NSFileProviderPartialContentFetching isn't available and build fails.

Hi, I have a file provider based MacOS application where i have a drive added and am trying to download a folder from that drive. The folder has sub folders and large files in it. After some time of download started, i keep getting below error. error: ["The operation could not be completed. Cannot allocate memory", [code: 12, domain: "NSPOSIXErrorDomain"] The download action is triggered via Finder's download icon(cloud icon with down arrow). I am using native URLSession to download the files from server. No third party library is used. What could be the possible reasons for "can not allocate memory" issue?

Hi all, i am trying to implement File Provider Extension. I have some scenarios that I can not figure out, User delete a file on local. 'deleteItem' callback is triggered. I send delete request to remote server. Remove server failed to apply deletion (for some reason deletion failed, blocked). I call 'completionHandler' with necessary error but here is the problem. File is removed in user local but exit in remote server. After some time 'deleteItem' callback is triggered multiple times for this file. I need to put same file in user local (rollback deletion) and stop triggered callbacks. I have a folder named "New folder". This folder is dataless (its sub items is not enumerated yet). User add a file named "a.txt" to this folder on remote server. I detect that addition. When I apply that addition with 'NSFileProviderChangeObserver' observers 'didUpdate' method then enumerate this directory "a.txt" is duplicated (a 2.txt is created). Is there any way to control folder named "New folder" is dataless (its sub items is not enumerated) so that I can skip file addition to prevent duplication. Any suggestion about above scenarios

Hi all, i am trying to implement File Provider Extension. I was able to enumerate remote storage directories to local via 'enumerateItems' function of NSFileProviderEnumerator. I can apply remote storage changes like newly created files/folders, move, rename and delete operations and successfully apply them to local with 'NSFileProviderChangeObserver' class 'didUpdate' and 'didDeleteItems' functions. However when file content is updated on remote server; If file content is not fetched(file is Dataless), i can not apply this change to local. When i call 'NSFileProviderChangeObserver' class 'didUpdate' function for changed file, only DateModified attribute is updated on finder, file size is not changed to new size. If file content has been fetched, When i call 'NSFileProviderChangeObserver' class 'didUpdate' function nothing is changed, file content stay depreciated Any suggestion how to fix it?

I want a user to be able to save a URL of a folder on a cloud share using the standard FileManager APIs. I'm testing with Dropbox in particular. The initial interaction is working (I can select a folder, save it as a bookmark, and scan the files in that folder). However, no changes made externally to the folder will be reflected in the app when I refresh the contents. Launching the Files app and browsing to the folder DOES show the updated contents, and once that step is complete, then my app will again show up-to-date contents. Is there perhaps some API I should be calling to trigger the Dropbox File Provider extension to update it's cache? Sample project demonstrating issue: https://github.com/dhennessy/FolderScan STEPS TO REPRODUCE Launch the app on a physical device Tap Choose, browse to folder on a Dropbox share, tap Open to select The app will show the contents of the folder (the 'test' folder) Switch to the Dropbox app and create a new subfolder of the test folder Return to the test app and tap Refresh. Notice that the changes do not appear Re-launching the app also does not show the changes Workaround Launch the Files app (or re-open the UIDocumentPickerViewController by tapping choose and then dismiss it) Tap Refresh and the changes will appear in the app Note: None of the other 'cloud file providers' (google drive, one drive, box) even allow the user to even select a folder.

I get the ApplicationSupportDirectory path like this: let path = NSSearchPathForDirectoriesInDomains(.applicationSupportDirectory, .userDomainMask, true)[0] as String however for FileProvider plugin it looks like: /var/mobile/Containers/Data/PluginKitPlugin/.../Library/Application Support/rclone.conf instead of what I get for an Application: /var/mobile/Containers/Data/Application/.../Library/Application Support I need a way to get the Application's Support Directory from the FileProvider plugin. Is that possible? If not, what other shared location I could use to access shared file between these two?

I use shared UserDefaults in my Swift FileProvider extension app suite. I share data between the containing app and the extension via User Defaults initialized with init(suiteName:). Everything was working fine before macOS 15 (Sequoia). I know that Sequoia changed the way the app group should be configured. My app group is know set to "$(TeamIdentifierPrefix)com.my-company.my-app". But the containing (UI) app and the Extension read and write from and to different plist locations although the same app-group is specified for both targets in XCode. The containing app reads and writes to "~/Library/Preferences/$(TeamIdentifierPrefix)com.my-company.my-app.plist" The Extension reads and writes to "~/Library/Containers/com.my-company.my-app.provider/Data/Library/Preferences$(TeamIdentifierPrefix)com.my-company.my-app.plist" Both of these locations seem completely illogical for shared UserDefaults. I checked the value returned by FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "$(TeamIdentifierPrefix)com.my-company.my-app" in both the containing app and the Extension and the value in both of them is the same but has nothing to do with the actual paths where the data is stored as provided above. (The value is as expected - "~/Library/Group Containers/$(TeamIdentifierPrefix)com.my-company.my-app/" P.S. Of course, $(TeamIdentifierPrefix), my-company and my-app here are placeholders for my actual values.

Dismiss the parent UIViewController before UIDocumentPickerViewController is fully visible. Swipe down or press the “Cancel” button in the picker. Occasionally, the system forcefully terminates the view service, causing a crash. Workarounds Tried (Unsuccessful) Using UIAdaptivePresentationControllerDelegate – Not Called for UIDocumentPickerViewController. Using viewDidDisappear to clean up – Not Called when the system terminates the picker. Forcing dismissal before presenting a new picker Reference to Line 42 in DOCRemoteViewController.m From the error traceback, we see a reference to DOCRemoteViewController.m line 42, which strongly suggests that UIDocumentPickerViewController relies on a background process to manage its lifecycle. Since we don’t have access to Apple’s private code, we assume that the DocumentManager service is trying to send a message to an already deallocated instance of UIDocumentPickerViewController, leading to a crash. One of the example wrapper implementation of us: class DocumentPickerViewController: UIViewController, UIDocumentPickerDelegate { private var picker: UIDocumentPickerViewController? weak var delegate: UIDocumentPickerDelegate? override func viewDidLoad() { super.viewDidLoad() print("📄 DocumentPickerViewController - viewDidLoad() called") setupDocumentPicker() } override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) print("📄 DocumentPickerViewController - viewDidAppear() called") } override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) print("📄 DocumentPickerViewController - viewWillAppear() called") } override func viewWillDisappear(_ animated: Bool) { super.viewWillDisappear(animated) print("📄 DocumentPickerViewController - viewWillDisappear() called") } override func viewDidDisappear(_ animated: Bool) { super.viewDidDisappear(animated) print("📄 DocumentPickerViewController - viewDidDisappear() called") } deinit { print("🗑 DocumentPickerViewController - deinit() called") } // MARK: - Setup Document Picker private func setupDocumentPicker() { picker = UIDocumentPickerViewController(forOpeningContentTypes: [.pdf]) picker?.delegate = self picker?.allowsMultipleSelection = false picker?.modalPresentationStyle = .formSheet if let picker = picker { present(picker, animated: false) { print("📄 Document Picker fully presented") } } } // MARK: - UIDocumentPickerDelegate Methods func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) { print("✅ User selected document(s): \(urls)") delegate?.documentPicker?(controller, didPickDocumentsAt: urls) dismissSelf() } func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) { print("❌ User cancelled document selection") delegate?.documentPickerWasCancelled?(controller) dismissSelf() } private func dismissSelf() { DispatchQueue.main.async { [weak self] in self?.dismiss(animated: true) } } } And logs for this implementation: 📄 Document Picker fully presented 📄 DocumentPickerViewController - viewDidAppear() called ❌ User cancelled document selection The view service did terminate with error: Error Domain=_UIViewServiceErrorDomain Code=1 "(null)" UserInfo={Terminated=disconnect method} 📄 DocumentPickerViewController - viewDidLoad() called 📄 Document Picker fully presented 📄 DocumentPickerViewController - viewDidAppear() called would appreciate any workarounds from the community to prevent crashes related to this issue!

Here's the problem I'm trying to solve: Create an iOS app which can scan the Downloads folder (where airdropped audio files arrive), identify audio media files, and play them, retaining some of its own metadata about them (basically, create textual notes mapped to timestamps and store that information in the apps own storage). I am not able to access that folder. I am able to get a path from NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.downloadsDirectory, FileManager.SearchPathDomainMask(arrayLiteral: FileManager.SearchPathDomainMask.userDomainMask), true) or a URL from NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.downloadsDirectory, FileManager.SearchPathDomainMask(arrayLiteral: FileManager.SearchPathDomainMask.userDomainMask), true) but let fileUrls = try fileManager.contentsOfDirectory(at:downloads, includingPropertiesForKeys: []) fails with an error that the folder does not actually exist, with or without a call to downloadsUrl.startAccessingSecurityScopedResource(). Determining whether this is a permissions issue, or if I'm getting a URL to an application-container local folder that has nothing to do with the one I am looking for is compounded by the fact that if I set the build setting Enable App Sandbox, then deployment to my phone fails with Failed to verify code signature. I have spent hours trying every possible combination of certificates and deployment profiles, and ensured that every possibly relevant certificate is trusted on my phone. Disable app-sandbox and it deploys fine, either with automatic signing or an explicit cert and profile. I have an entitlements file with the following - though, without the ability to enable app sandbox and run it on a phone with actual contents in the downloads folder, it is probably not affecting anything: &lt;key&gt;com.apple.security.files.downloads.read-only&lt;/key&gt; &lt;true/&gt; &lt;key&gt;com.apple.security.files.user-selected.read-only&lt;/key&gt; &lt;true/&gt; &lt;key&gt;com.apple.security.app-sandbox&lt;/key&gt; &lt;true/&gt; So, questions: Should the URL returned by the above call be the Downloads/ folder airdropped to in the first place? Or is it a URL to some app-local folder that does not exist? Does the entitlement com.apple.security.files.downloads.read-only even allow an app to list all files in the downloads directory (presumably asking the user's permission the first time), or does the permission only get requested when using a picker dialog? (the point here is to find any new audio files without making the user jump through hoops) If I could get it deployed with app-sandbox enabled, would the above code work? Backstory: I'm a software engineer, audio plugin author, Logic Pro user and musician. My workflow (and probably many other Logic user's) for work-in-progress music is to airdrop a mix to my phone, listen to it in a variety of places, make notes about what to change, edit - rinse and repeat. For years I used VLC for iOS to keep and play these in-progress mixes - you could airdrop and select VLC as the destination (yes, Logic can add to your Apple Music library, but trust me, you do not want 20 revisions of the same song cluttering your music library and sync'd to all your devices). Last year, the behavior of Airdrop changed so that the target app for audio is always Files, period, wrecking that workflow. While I eventually discovered that, with an elaborate and non-obvious dance of steps, it is possible to copy files into VLC's folders, and make them available that way, it is inconvenient, to say the least - and VLC is less than fabulous anyway - it would be nice to have an app that could associate to-do notes with specific timestamps in a tune, A/B compare sections between old and new versions and things like that. So, figuring sooner or later I was going to get into a car accident futzing with the Files app to listen to mixes while driving, perhaps I should write that app. But the ability to do that at all relies on the ability of an app to list and access the Downloads folder airdropped audio files land in (assuming the user has given permission to access it, but that should be needed once).

Hi everyone, I am a beginner in iOS/Swift programming. I'm trying to develop a mobile application that allows to mount a network drive in the iphone Files application via the WebDav protocol. I saw on the internet that WebDav is no longer implemented in iOS because considered deprecated by apple. To accomplish this task, I decided to separate responsibilities as follows: Framework: WebDav (responsible for communication with the WebDav server) FileProviderExtension: FileBridge (Responsible for bridging the gap between the WebDav Framework and the iOS Files app) Main App I also have an AppGroup that includes the main application and the fileproviderextension Initially, to measure the feasibility and complexity of this task, I'd like to make a simplistic version that simply displays the files on my drive in the Files app, without necessarily being able to interact with them. FileProviderExtension.swift: import FileProvider import WebDav class FileProviderExtension: NSObject, NSFileProviderReplicatedExtension { private var webDavService: WebDavService? required init(domain: NSFileProviderDomain) { super.init() self.webDavService = WebDavService(baseURL: URL(string: "https://www.mydrive.com/drive")!) } func invalidate() { // TODO: cleanup any resources } func item(for identifier: NSFileProviderItemIdentifier, request: NSFileProviderRequest, completionHandler: @escaping (NSFileProviderItem?, Error?) -> Void) -> Progress { let progress = Progress(totalUnitCount: 1) Task { do { if let items = try await webDavService?.propfind(path: identifier.rawValue, depth: 1), let item = items.first(where: { $0.itemIdentifier == identifier }) { completionHandler(item, nil) } else { completionHandler(nil, NSError(domain: NSCocoaErrorDomain, code: NSFileNoSuchFileError, userInfo: nil)) } } catch { completionHandler(nil, error) } } return progress } func fetchContents(for itemIdentifier: NSFileProviderItemIdentifier, version requestedVersion: NSFileProviderItemVersion?, request: NSFileProviderRequest, completionHandler: @escaping (URL?, NSFileProviderItem?, Error?) -> Void) -> Progress { let progress = Progress(totalUnitCount: 1) Task { do { guard let service = webDavService else { throw WebDavError.invalidResponse } let data = try await service.get(fileAt: itemIdentifier.rawValue) let tempURL = FileManager.default.temporaryDirectory.appendingPathComponent(itemIdentifier.rawValue) try data.write(to: tempURL) completionHandler(tempURL, nil, nil) } catch { completionHandler(nil, nil, error) } } return progress } func createItem(basedOn itemTemplate: NSFileProviderItem, fields: NSFileProviderItemFields, contents url: URL?, options: NSFileProviderCreateItemOptions = [], request: NSFileProviderRequest, completionHandler: @escaping (NSFileProviderItem?, NSFileProviderItemFields, Bool, Error?) -> Void) -> Progress { // TODO: a new item was created on disk, process the item's creation completionHandler(itemTemplate, [], false, nil) return Progress() } func modifyItem(_ item: NSFileProviderItem, baseVersion version: NSFileProviderItemVersion, changedFields: NSFileProviderItemFields, contents newContents: URL?, options: NSFileProviderModifyItemOptions = [], request: NSFileProviderRequest, completionHandler: @escaping (NSFileProviderItem?, NSFileProviderItemFields, Bool, Error?) -> Void) -> Progress { // TODO: an item was modified on disk, process the item's modification completionHandler(nil, [], false, NSError(domain: NSCocoaErrorDomain, code: NSFeatureUnsupportedError, userInfo:[:])) return Progress() } func deleteItem(identifier: NSFileProviderItemIdentifier, baseVersion version: NSFileProviderItemVersion, options: NSFileProviderDeleteItemOptions = [], request: NSFileProviderRequest, completionHandler: @escaping (Error?) -> Void) -> Progress { // TODO: an item was deleted on disk, process the item's deletion completionHandler(NSError(domain: NSCocoaErrorDomain, code: NSFeatureUnsupportedError, userInfo:[:])) return Progress() } func enumerator(for containerItemIdentifier: NSFileProviderItemIdentifier, request: NSFileProviderRequest) throws -> NSFileProviderEnumerator { return FileProviderEnumerator(enumeratedItemIdentifier: containerItemIdentifier, service: webDavService) } } Here's the code I use to initialize my domain in the main app files: fileprivate func registerFileProviderDomain() { let domainIdentifier = NSFileProviderDomainIdentifier("FileProviderExtension Bundle Identifier") let domain = NSFileProviderDomain(identifier: domainIdentifier, displayName: "My Drive") NSFileProviderManager.add(domain) { error in NSFileProviderManager.add(domain) { error in if let error = error { print("Error cannot add domain file provider : \(error.localizedDescription)") } else { print("Success domain file provider added") } } } I can't get rid of the Error : Error cannot add domain file provider : The operation couldn’t be completed. Invalid argument. I don't know what I'm missing Please help me understand

When running a Mac Catalyst app that uses DocumentGroup, the app fails to display the document content. The document picker works as expected, but creating a new document or opening an existing one results in an empty window. This issue occurs regardless of whether “Optimize for Mac” or “Scale iPad” is selected. Steps to Reproduce: 1. Download the sample project provided by Apple for building a document-based app in SwiftUI. 2. Delete the macOS version of the project. 3. Add a Mac Catalyst version of the app. 4. In the Mac Catalyst settings, select “Optimize for Mac” (the bug also appears if it is “Scale iPad”). 5. Run the project on macOS. Expected Result: The app should correctly display the content of the document when creating or opening it. Actual Result: The app opens an empty window when a new document is created or an existing one is opened. Impact: We have received multiple 1-star reviews, and our retention has dropped by two-thirds due to this issue. Environment: Xcode 16.1; macOS 15.1 & 15.2 (on 15.0 it works fine) Has anyone experienced the same issue? I filed multiple reports so far.

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.

We use File Provider Extension in our main app, and it is working fine. We always call "NSFileProviderManager.add(_:completionHandler:)" function to start the extension, and "NSFileProviderManager.disconnect(reason:options:completionHandler:)" to temporarily quit the extension with the reason which will be shown in the Finder at the top of the FP domain folder. But sometimes, when the main app calls the above functions, the following issue cases occur, and the extension does not start/stop: The completionHandler function doesn't get called (As we noticed, we waited for 2 minutes. Then, we restarted the main app.) One of the following errors returned: i) "The application cannot be used right now", ii) "Couldn't communicate with the helper application", iii) "No valid file provider found with identifier" Here, the important thing is that restarting the main app once or twice clears the issue, and the extension starts. But it is frustrating to restart the app each time we get this issue. We want to know the following things: Why and when do the above issues occur? Why do they occur only sometimes, and how does the app restart clear the issue? How do we resolve them without restarting the main app? This has become a critical issue, so a detailed explanation would be greatly appreciated. TIA.

iPhone 15pro iOS 18.2 Downloaded files cannot be located anywhere in Files, only by accessing Downloads in Safari. I have tried setting download folder to various locations, iCloud, Phone, Google Disk, but nothing is stored. Has an invisible cache or temp folder been introduced? If so, it is a total fail: When press-holding any file in Safari download, the normal file action options (Quick Look, share, store to Files, etc) are not available. When clicking any file it opens any of several apps that has this file type associated with it, and there is no way to change the default app or disable the forced opening of an app. I tried deleting the app opening .csv (in this case OneDrive), and another irrelevant app opened. There seems to be a hierarchy of apps-file types, and it has no logic to it. in Chrome behaviour is as expected. Chrome vs. Safari screen recordings: https://shorturl.at/my3Oy

Dear Apple engineers, Is it possible to make a fileprovider cloud volume mount path independent of the user's home folder in order to have constant path across desktop clients when files are referenced / placed by applications like Adobe Creative Cloud ? Ideally mount or link the fileprovider cloud volume under /Volumes Thanks,

I am using a Mac Catalyst with SwiftUI for our document-based app with DocumentGroup. The issue is that when we create a new document or open an existing one, the opened view is completely blank. It is only blank/empty when the "Optimzie for Mac" is checked. If it is "Scaled t oMatch iPad", then it works well. Xcode 16.1 macOS 15.1 struct DocumentGroupTestApp: App { var body: some Scene { DocumentGroup(newDocument: WritingAppDocument()) { file in TestView() // it is empty when it gets opened. It does not work if the option "Optimize for Mac" is checked. If it is scale iPad, then it works. } } } struct TestView: View { var body: some View { Text("Hello, World!") } }

Hello, I'm seeing a strange error on another user's device where the SwiftUI file importer doesn't do anything at all. When selecting multiple files and hitting "open", the importer just freezes. Here's a video showing the problem: https://streamable.com/u5grgy I'm unable to replicate on my own device, so I'm not sure what could be going on. I have startAccessingSecurityScopedResource and stopAccessingSecurityResource everywhere I access a file from fileImporter as well.
