I have an ios files extension for some cloud that allows colons in its files and folders names. However NSFileProviderItem.filename replaces colons with a slash (/) and they displays incorrectly in Files.appFor example, item with name Photos: 2018 displays as Photos/ 2018How can I insert colon symbol in filename?

Hello!I have a problem with working set enumerator (Recents tab) in Files app. I implement a working enumerator for Folders, it runs enumerateItems(for observer method when I move to the folder in UI and everything works fine.And I have a different enumerator for working set too, but it is not created and enumerated anything.override func enumerator(for containerItemIdentifier: NSFileProviderItemIdentifier) throws -> NSFileProviderEnumerator { let maybeEnumerator: NSFileProviderEnumerator? if (containerItemIdentifier == NSFileProviderItemIdentifier.rootContainer) { let directory = repository.directory(for: containerItemIdentifier)! maybeEnumerator = FileProviderFolderEnumerator() } else if (containerItemIdentifier == NSFileProviderItemIdentifier.workingSet) { maybeEnumerator = FileProviderWorkingSetEnumerator() // not called } else { _ = repository.item(for: containerItemIdentifier) if repository.isDirectory(at: containerItemIdentifier) { let directory = repository.directory(for: containerItemIdentifier)! maybeEnumerator = FileProviderFolderEnumerator() // works fine } else { maybeEnumerator = FileProviderItemEnumerator() } } guard let enumerator = maybeEnumerator else { throw NSError(domain: NSCocoaErrorDomain, code: NSFeatureUnsupportedError, userInfo:[:]) } return enumerator }I'm trying to call working set enumerator in startProvidingItem method using signal, but it doesn't work.override func startProvidingItem(at url: URL, completionHandler: @escaping ((_ error: Error?) -> Void)) { loadItem { //when done with loading NSFileProviderManager.default.signalEnumerator( for: NSFileProviderItemIdentifier.workingSet, completionHandler: { error in if let err = error { print(err) } } } }Does FileProviderWorkingSetEnumerator initialize automatically when I open Recents tab in Files app? Should I call it somehow directly from FileExtension?Thank you!
