We have a macOS app that has a Photos Extension, which shares documents with the app via an app group container. Historically we used to have an iOS-style group identifier (group.${TeamIdentifier}${groupName}), because we were lead by the web interface in the developer portal to believe this to be the right way to name groups. Later with the first macOS 15 betas last year there was a bug with the operating system warning users, our app would access data from different apps, but it was our own app group container directory. Therefore we added a macOS-style group identifier (${TeamIdentifier}${groupName}) and wrote a migration of documents to the new group container directory. So basically we need to have access to these two app group containers for the foreseeable future. Now with the introduction of iOS-style group identifiers for macOS, Xcode Cloud no longer archives our app for TestFlight or AppStore, because it complains: ITMS-90286: Invalid code signing entitlements - Your application bundle’s signature contains code signing entitlements that aren’t supported on macOS. Specifically, the “[group.${TeamIdentifier}${groupName}, ${TeamIdentifier}${groupName}]” value for the com.apple.security.application-groups key in isn’t supported. This value should be a string or an array of strings, where each string is the “group” value or your Team ID, followed by a dot (“.”), followed by the group name. If you're using the “group” prefix, verify that the provisioning profile used to sign the app contains the com.apple.security.application-groups entitlement and its associated value(s). We have included the iOS-style group identifier in the provisioning profile, generated automatically, but can't do the same for the macOS-style group identifier, because the web interface only accepts identifiers starting with "group". How can we get Xcode Cloud to archive our app again using both group identifiers? Thanks in advance

Accessing a directory on my custom distributed filesystem results in a kernel panic. According to the backtrace, the last function called before the panic is triggered is mac_label_verify(). See the backtrace file attached. mac_label_verify-panic.txt The panic manifests itself given the following conditions: Machine-a: make a directory in Finder. Machine-b: remove the directory created on machine-a in Finder. Machine-a: access the directory removed on machine-b in Finder. Kernel panic ensues. The panic is reproducible on both Apple Silicon and x86-64. The backtrace is for x86-64 as I wasn't able to symbolicate it on Apple Silicon. Not sure how to tackle this one. Any pointers would be much appreciated.

Is it possible to change the default save dialog that appears when creating a document based MacOS app in SwiftUI? I have a basic FileDocument struct that gets called to a view using a DocumentGroup scene. struct MyFile: FileDocument { static let readableContentTypes: [UTType] = [.myFileType] static let writeableContentTypes: [UTType] = [.myFileType] var list: [String] init(configuration: ReadConfiguration) throws { let data = configuration.file.regularFileContents! let JSONDecoder = JSONDecoder() do { try list = JSONDecoder.decode([String].self, from: data) } catch { throw CocoaError(.fileReadCorruptFile) } } func fileWrapper(configuration: WriteConfiguration) throws -> FileWrapper { let JSONEncoder = JSONEncoder() JSONEncoder.outputFormatting = .prettyPrinted do { data = try JSONEncoder.encode(self.list) } catch { print(error.localizedDescription) throw CocoaError(.fileWriteUnknown) } return .init(regularFileWithContents: data) } } This gets called at the DocumentGroup DocumentGroup(newDocument: MyFile(), editor: { document in ContentView(document: document.$document) }) But when I save the file, I want the save dialog that appears to have something like a 'Tags' textField that can also store information about the file. Something similar to this: (https://i.sstatic.net/AJQ3YNb8.png) From what I can find, there isn't much information about this other than manually creating an NSSavePanel class and overriding the current save function

The application search for the occurences of a string into files and folders. Everything work fine until I enable sanbox. Then opendir(path_to_folder) report "Operation not permitted". By example dp = opendir("/Users/alain/Desktop"); set dp to NULL for my own Desktop. The application need only read access. How can I get this access ?

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 am getting recurring errors running code on macOS 15.1 on arm that is using a volume mounted from a machine running macOS 14.7.1 on x86. The code I am running copies files to the remote volume and deletes files and directories on the remote volume. The files and directories it deletes are typically files it previously had copied. The problem is that I get permission failures trying to delete certain directories. After this happens, if I try to list the directory using Terminal on the 15.1 system, I get a strange error: ls -lA TestVAppearances.app/Contents/runtime-arm/Contents total 0 ls: fts_read: Permission denied If I try to list the directory on the target (14.7.1) system, there is no error: TestVAppearances.app/Contents/runtime-arm/Contents: total 0

I have some questions regarding App Group Id's and use of the FileManager during an Appstore iOS transfer. I've read a lot of the topics here that cover app groups and iOS, but it's still unclear exactly what is going to happen during transfer when we try to release an updated version of the app from the new account. We're using this method FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.com.foo.bar") to store files on the device that are important for app launch and user experience. Once we transfer the app and begin the process of creating a new version under the new account will we be able to read the files that are stored using this app group id under the new account? What steps do we need to take in order to handle this and continue being able to access these files? It seems like the app group is not transferred in the process? I've seen some users mention they removed the app group from the original account and created it again under the receiving account (with notes mentioning this is undocumented behavior). These conversations we're centered around Shared user defaults, and that applies as well but I'm more concerned with reading the values from the file system. Thanks!

Hi There, I have an app which access the media library, to save and load files. Since the IOS 18.2, the access to the media library stopped working. Now, I've noticed that our App doesn't show in the List of apps with access to Files ( Privacy & Security -> Files & Folders). Weird behavior is that, one iPhone with iOS 18.3.1 can access to the Files but others no, same iOS version 18.3.1. Test on Simulators (MAC) and works fine also. My info.plist file have the keys to access media library for long time and hasn't changed (at least in the las 4 years) including the key "Privacy - Media Library Usage Description". Also, I've noticed, that the message (popup) that request access to the media library, when using the app for the first time, doesn't show up anymore. We request access to the network (wifi) and this message still showing up but no the media library. I'm using Visual Studio with Xamarin on a MAC. I really appreciate any help you can because is very odd behavior and this started from the iOS 18.2.

Hello, I'm a newer Xcode developer trying to debug an error I'm getting in my iOS app. I'm using this code to get file content: //inputFile = "here is my file name with no extension" let filepath = Bundle.main.path(forResource: inputFile, ofType: "txt") //filepath = "/Users/username/Library/Developer/CoreSimulator/Devices/[DeviceGUID]/data/Containers/Bundle/Application/[AppGUID]/AppName.app/here is my file name with no extension.txt" let fileContent = try String(contentsOfFile: filepath) That line generates a runtime error: error NSError domain: "NSCocoaErrorDomain" - code: 264 0x0000600000c74d20 Xcode 16.2 on macOS Sequoia 15.1.1 I had this code working... I had to step away from the code for a few months; I updated Xcode and now I'm getting this error. (I could've screwed the code up). I navigated to the directory and the file is there. Anybody have any ideas? Thank you! Hoss

Hi. I am facing a panic in distributed virtual filesystem of my own making. The panic arises on attempt of copying a large folder, or writing a large file (both around 20gb). An important note here is that the amount of files we try to copy is larger than available space (for testing purposes, the virtual file system had a capacity of 18 gigabytes). The panic arises somewhere on 12-14gigabytes deep into copying. On the moment of panic, there are still several gigabytes of storage left. The problem is present for sure for such architectures and macOS versions: Sonoma 14.7.1 arm64e Monterey 12.7.5 arm64e Ventura 13.7.1 intel Part from panic log from Ventura 13.7.1 intel, with symbolicated addresses: panic(cpu 2 caller 0xffffff80191a191a): watchdog timeout: no checkins from watchdogd in 90 seconds (48 total checkins since monitoring last enabled) Panicked task 0xffffff907c99f698: 191 threads: pid 0: kernel_task Backtrace (CPU 2), panicked thread: 0xffffff86e359cb30, Frame : Return Address 0xffffffff001d7bb0 : 0xffffff8015e70c7d mach_kernel : _handle_debugger_trap + 0x4ad 0xffffffff001d7c00 : 0xffffff8015fc52e4 mach_kernel : _kdp_i386_trap + 0x114 0xffffffff001d7c40 : 0xffffff8015fb4df7 mach_kernel : _kernel_trap + 0x3b7 0xffffffff001d7c90 : 0xffffff8015e11971 mach_kernel : _return_from_trap + 0xc1 0xffffffff001d7cb0 : 0xffffff8015e70f5d mach_kernel : _DebuggerTrapWithState + 0x5d 0xffffffff001d7da0 : 0xffffff8015e70607 mach_kernel : _panic_trap_to_debugger + 0x1a7 0xffffffff001d7e00 : 0xffffff80165db9a3 mach_kernel : _panic_with_options + 0x89 0xffffffff001d7ef0 : 0xffffff80191a191a com.apple.driver.watchdog : IOWatchdog::userspacePanic(OSObject*, void*, IOExternalMethodArguments*) (.cold.1) 0xffffffff001d7f20 : 0xffffff80191a10a1 com.apple.driver.watchdog : IOWatchdog::checkWatchdog() + 0xd7 0xffffffff001d7f50 : 0xffffff80174f960b com.apple.driver.AppleSMC : SMCWatchDogTimer::watchdogThread() + 0xbb 0xffffffff001d7fa0 : 0xffffff8015e1119e mach_kernel : _call_continuation + 0x2e Kernel Extensions in backtrace: com.apple.driver.watchdog(1.0)[BD08CE2D-77F5-358C-8F0D-A570540A0BE7]@0xffffff801919f000->0xffffff80191a1fff com.apple.driver.AppleSMC(3.1.9)[DD55DA6A-679A-3797-947C-0B50B7B5B659]@0xffffff80174e7000->0xffffff8017503fff dependency: com.apple.driver.watchdog(1)[BD08CE2D-77F5-358C-8F0D-A570540A0BE7]@0xffffff801919f000->0xffffff80191a1fff dependency: com.apple.iokit.IOACPIFamily(1.4)[D342E754-A422-3F44-BFFB-DEE93F6723BC]@0xffffff8018446000->0xffffff8018447fff dependency: com.apple.iokit.IOPCIFamily(2.9)[481BF782-1F4B-3F54-A34A-CF12A822C40D]@0xffffff80188b6000->0xffffff80188e7fff Process name corresponding to current thread (0xffffff86e359cb30): kernel_task Boot args: keepsyms=1 Mac OS version: 22H221 Kernel version: Darwin Kernel Version 22.6.0: Thu Sep 5 20:48:48 PDT 2024; root:xnu-8796.141.3.708.1~1/RELEASE_X86_64 The origin of the problem is surely inside my filesystem.

Hello guys, I wanted to reach out to see if any of you have experienced or come across an issue we are facing in our organization. We are encountering a campus-wide problem where Macs are take an unusually long time to delete files on external drives formatted with ExFAT. We manage these Macs through Jamf Pro, and numerous policies are applied when the devices are enrolled. We have tested the issue in both scenarios—when the Macs are connected to the domain and when they are not—and the slow deletion persists in both cases. At this point, we are unsure whether the issue lies on our end or if it is related to the operating system itself. If anyone has found a fix or workaround for this problem, we would appreciate your input.

Is there a suitable UTType type to satisfy the need to pick up only SpatialVideo in UIDocumentPickerViewController? I already know that PHPickerFilter in PHPickerViewController can do this, but not in UIDocumentPickerViewController. Our app needs to adapt both of these ways to pick spatial videos So is there anything that I can try in UIDocumentPickerViewController to fulfill such picker functionality?

Hello, es_event_mount_t includes statfs structure. This structure has the field 'f_type' which defines type of filesystem. However, man page says nothing about possible values of this field. What is the best way to define file system type? Can I use 'f_type' or 'f_fstypename'? If so, are there any constants in header files which can be used? Thank you for your help!

i recently upgraded to sequoia, and now, more often than not, when running in the debugger, opening my database causes a hang: When i run outside the debugger, it opens just fine. I suspect it has to do with "full disk access"? but i've given my app full disk access. i've also set Qt and Xcode to have "Allow apps to use developer tools" permissions. as a test i also added my app into that permission group, all to no avail. the path to the DB being opened is in my user's Music folder, and having full disk access gives permission for everything, including things in that folder. confused!

Dear Apple Developer Experts, We're experiencing an intermittent issue with WKWebView in our macOS application where local HTML file access is occasionally denied by the sandbox, despite proper implementation and permissions. We seek your guidance in understanding and resolving this issue. Issue Description: The WKWebView occasionally fails to load local HTML files stored in the app's Contents/Resources directory Error occurs in WebKit Networking Process with sandbox denial Issue is intermittent and can be resolved by app restart or WebKit Networking Process restart Affects all local HTML files in the same directory once the issue occurs Technical Details: Error from Kernel Log: 2025-02-07 14:57:17.179821 +0800 kernel Sandbox: com.apple.WebKit.Networking(58661) deny(1) file-read-data /Applications/DingTalk.app/Contents/Resources/webcontent/contact-2024.html WKWebView Delegate Error (captured in WKNavigationDelegate method): (void)webView:(WKWebView *)webView didFailProvisionalNavigation:(WKNavigation *)navigation withError:(NSError *)error Error Details: Domain: NSPOSIXErrorDomain Code: 1 Description: "Operation not permitted" UserInfo: { networkTaskMetricsPrivacyStance: Unknown, _NSURLErrorFailingURLSessionTaskErrorKey: LocalDataTask <3694CA1E-481B-4E06-975D-E3A56AD56C0F>.<1>, _kCFStreamErrorDomainKey: 1, _kCFStreamErrorCodeKey: 1 } Key Observations: Error is captured in WKNavigationDelegate's didFailProvisionalNavigation method The issue affects all local HTML files in the same directory once it occurs Temporary workarounds we've discovered: Restarting the application completely resolves the issue Without restarting the application, terminating the "WebKit Networking Process" via Activity Monitor causes the process to automatically restart, and this resolves the issue and load works again Additional Information: We've collected complete system diagnostics (system_logs.logarchive) at the time of failure The issue appears similar to discussions in Apple Developer Forums (https://developer.apple.com/forums/thread/110072), though we're uncertain if it's the same root cause We've prepared a minimal demo project demonstrating: Our release version app can be downloaded from: https://dtapp-pub.dingtalk.com/dingtalk-desktop/mac_dmg/Release/M1-Beta/DingTalk_v7.6.45_43521682_universal.dmg?spm=0.0.0.0.UuwovG&file=DingTalk_v7.6.45_43521682_universal.dmg for examining our app's codesign, sandbox, and entitlements configurations if needed Important Investigation Finding: We attempted to simulate the issue by using chmod 000 /path/to/test.html, but this produces a different error: CopyError Domain=NSURLErrorDomain Code=-1102 Description="You do not have permission to access the requested resource."

Questions: Is this a known issue with the WebKit sandbox in recent macOS versions? Are there recommended best practices or workarounds to prevent this sandbox denial? Could this be related to the WebKit Networking Process's sandbox configuration? Are there additional diagnostics or logs we should collect to help investigate this issue? We appreciate your assistance in investigating this issue. Please let us know if you need any additional information or clarification.

The SwiftUI Playground code below demonstrates that a .jpeg image can be read and written to the iOS file system. While, a.png image can only be read; the writing request appears to be ignored. Can anyone please tell me how to code to save a .png image using SwiftUI to the iOS file system. Code: import SwiftUI import UniformTypeIdentifiers /* (Copied from Playground 'Help' menu popup.) UIImage Summary An object that manages image data in your app. You use image objects to represent image data of all kinds, and the UIImage class is capable of managing data for all image formats supported by the underlying platform. Image objects are immutable, so you always create them from existing image data, such as an image file on disk or programmatically created image data. An image object may contain a single image or a sequence of images for use in an animation. You can use image objects in several different ways: Assign an image to a UIImageView object to display the image in your interface. Use an image to customize system controls such as buttons, sliders, and segmented controls. Draw an image directly into a view or other graphics context. Pass an image to other APIs that might require image data. Although image objects support all platform-native image formats, it’s recommended that you use PNG or JPEG files for most images in your app. Image objects are optimized for reading and displaying both formats, and those formats offer better performance than most other image formats. Because the PNG format is lossless, it’s especially recommended for the images you use in your app’s interface.

Hi. I am developing a custom virtual file system and facing such behaviour: Upon using some graphical apps, for example Adobe Media Encoder, attempting to navigate inside my filesystem deeper than root folder will fail - nothing will happen on "double click" on that subfolder. Another problem, is that whether I try to re-navigate into root directory, it will be empty. The problem is not present for most GUI apps - for example navigation inside Finder, upon choosing download path for file in Safari, apps like Microsoft Word, Excel and other range of applications work totally correctly. A quick note here. From what I have seen - all apps that work correctly actually have calls to VFS_VGET - a predefined vfs layer hook. Whether the Adobe Media Encoder does not call for it - neither in my filesystem, nor in Samba, so my guess is that some applications have different browsing and retrieving algorithm. Is there anything I should examine further ? Default routines (vnop_open, vnop_lookup, vnop_readdir, vnop_close) behave as expected, without any errors. P.S. This application (Adobe Media Encoder) works properly on Samba.

I'm working on a macOS app that I want to give "Full Disk Access". When I run from Xcode, I get "permission denied" errors when reading a file in my home directory. What can I do so that I can run and debug from Xcode? I dragged the binary from the derived data folder to the System Preferences list for Full Disk Access, but that seems to do nothing.

On macOS, the Finder allows to connect to a server and store the login credentials. When creating a bookmark to a file on a server and resolving it again, the server is mounted automatically (unless I provide the option URL.BookmarkResolutionOptions.withoutMounting). I just tried connecting to my Mac from my iPad via SMB in the Files app and storing a bookmark to a file on the server, but disconnecting the server and trying to resolve the bookmark throws the error (I translated the English text from Italian): Error Domain=NSFileProviderErrorDomain Code=-2001 "No file provider was found with the identifier "com.apple.SMBClientProvider.FileProvider"'" UserInfo={NSLocalizedDescription=No file provider was found with the identifier "com.apple.SMBClientProvider.FileProvider"., NSUnderlyingError=0x302a1a340 {Error Domain=NSFileProviderErrorDomain Code=-2013 "(null) "}} Every time I disconnect and reconnect to the server, selecting the same file returns a different path. The first time I got /private/var/mobile/Library/LiveFiles/com.apple.filesystems.smbclientd/WtFD3Ausername/path/to/file.txt The next time WtFD3A changed to EqHc2g and so on. Is it not possible to automatically mount a server when resolving a bookmark on iOS? The following code allows to reproduce the issue: struct ContentView: View { @State private var isPresentingFilePicker = false @AppStorage("bookmarkData") private var bookmarkData: Data? @State private var url: URL? @State private var stale = false @State private var error: Error? var body: some View { VStack { Button("Open") { isPresentingFilePicker = true } if let url = url { Text(url.path) } else if bookmarkData != nil { Text("couldn't resolve bookmark data") } else { Text("no bookmark data") } if stale { Text("bookmark is stale") } if let error = error { Text("\(error)") .foregroundStyle(.red) } } .padding() .fileImporter(isPresented: $isPresentingFilePicker, allowedContentTypes: [.data]) { result in do { let url = try result.get() if url.startAccessingSecurityScopedResource() { bookmarkData = try url.bookmarkData() } } catch { self.error = error } } .onChange(of: bookmarkData, initial: true) { _, bookmarkData in if let bookmarkData = bookmarkData { do { url = try URL(resolvingBookmarkData: bookmarkData, bookmarkDataIsStale: &stale) } catch { self.error = error } } } } }
