Hi Is there a way to check if a file at a specified URL is open and being edited by another application. Assuming that we have permission to access the file at the URL.

I want to implement quota feature to my file provider extension. I am able to keep track of materialized files total size. (Content download and edit operations) However I cannot detect file eviction operation (User right click to file and select "Remove Download"). Is there anyway to detect this action Or any suggestion to keep track of materialized files total size?

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?
