Issues with ShareLink under macOS (with sample code updated on March 1, 2023)

struct ShareButton: View { ... let byLine = currentlyReading.book.byLine ShareLink( item: image, message: Text(byLine), preview: SharePreview(byLine, image: image)) When sharing a book, the following is logged in console and the message field is not filled by byline as expected: BookClub[14058:2642949] [NSExtension] Extension request contains input items but the extension point does not specify a set of allowed payload classes. The extension point's NSExtensionContext subclass must implement `+_allowedItemPayloadClasses`. This must return the set of allowed NSExtensionItem payload classes. In future, this request will fail with an error.

Sample code doesn't compile as contextAction has been replaced

Sample code fails to compile with Xcode 14.1 beta 3 (14B5033e) as contextAction has been removed/replaced. // Compile error: Value of type 'some View' has no member 'contextAction' #if os(macOS) .contextAction(forSelectionType: Book.ID.self) { books in It looks like it has been replaced with contextMenu(forSelectionType:menu) with a slight difference.

.fileExporter issue

In sample code Building a Great Mac App with SwiftUI | Apple Developer Documentation, selecting Export… from the menu does nothing. It looks like .fileExporter needs to be applied to the the enclosing Section instead of the Button. CommandGroup(replacing: .importExport) { Section { Button("Export…") { isShowingExportDialog = true } } // Doesn't work when it is applied to the button, // but works when applied to the section .fileExporter( isPresented: $isShowingExportDialog, document: store, contentType: Store.readableContentTypes.first!) { result in } }

How to use NavigationSplitView instead of NavigationView where binding was used

It looks like passing a binding (instead of value) to a detail view is not possible with NavigationSplitView. For example, how to adopt NavigationSplitView in sample app Date Planner — Sample Apps Tutorials | Apple Developer Documentation does not seem straight forward. The only way seems to be to use ObservableObjects and use separate update methods on data. ...     ForEach(eventData.sortedEvents(period: period)) { $event in         NavigationLink {             EventEditor(event: $event)         } label: {             EventRow(event: event)         }
