After I receive an apns request. func enumerateItems(for observer: NSFileProviderEnumerationObserver, startingAt page: NSFileProviderPage) will be called. And I start fetch new items from my server. If new items have been deleted something that old items which already showed to the user contains. These have been deleted items will not disappear on the screen. func enumerateItems(for observer: NSFileProviderEnumerationObserver, startingAt page: NSFileProviderPage) {         task = Task {             do {                 let flat = MediaItemReference.flat(enumeratedItemIdentifier == .rootContainer ? root : enumeratedItemIdentifier.rawValue)                 guard let uuid = UUID(uuidString: flat.identifier) else {                     observer.finishEnumeratingWithError(FileProviderError.other)                     return                 }                 let fileContents = try await WebApi.getSubForFileProvider(uuid)                 let refs = fileContents.map { fileContent -> MediaItemReference in                     InfoPool.shared.set(fileContent.uuid.uuidString, value: fileContent)                     return MediaItemReference(                         identifier: fileContent.uuid.uuidString,                         isDirectory: fileContent.isDictionary,                         filename: fileContent.name,                         father: uuid.uuidString)                 }                 let items = refs.map(FileProviderItem.init(reference:))                 observer.didEnumerate(items)                 observer.finishEnumerating(upTo: nil)             } catch {                 print("=>", error.localizedDescription)                 observer.finishEnumeratingWithError(error)             }         }     }

What is the difference between NSFileProviderWorkingSetContainerItemIdentifier and NSFileProviderRootContainerItemIdentifier. And what NSFileProviderWorkingSetContainerItemIdentifier is? What time will files app create NSFileProviderWorkingSetContainerItemIdentifier?

After I updated xcode to 13.3 version, almost all mt spm project warns. SourcePackages/checkouts/SwiftUI-MediaPicker/SwiftUI.UIViewControllerRepresentable:7:24: Static method '_makeView(view:inputs:)' isolated to global actor 'MainActor' can not satisfy corresponding requirement from protocol 'View' It's pretty bad, because I don' wanna any warnings.

Menu {                 Button(action: {                     // TODO: support live text                 }) {                     Label("Live Text", systemImage: "camera.viewfinder")                 }             } label: {                 Text("Hi")             } How can I present the live text view in swiftUI
