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)
}

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
}
}
import RegexBuilder
switch "abc" {
case /\w+/:
print("It's a word!")
}
Gives an error:
expression failed to parse:
error: x.xcplaygroundpage:7:6: error: expression pattern of type 'Regex<Substring>' cannot match values of type 'String'
case /\w+/:
^
x.xcplaygroundpage:7:6: note: overloads for '~=' exist with these partially matching parameter lists: (Substring, String)

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.
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.
