Embedding a NavigationStack inside the detail view of a NavigationSplitView is described by the Apple documentation: https://developer.apple.com/documentation/swiftui/navigationsplitview However, I would like to do the opposite: embedding a NavigationSplitView inside a NavigationStack. I have found no hint in the documentation about why this shouldn't be possible, but it does not appear to be working consistently. There are many use cases where you might want to do this. E.g. you have an eBook reader that starts with a list of books (e.g. a Grid inside a NavigationStack), and when you open a book, you end up in a NavigationSplitView showing the chapter hierarchy in a sidebar. Here, you wouldn't want to have the list of books as a second sidebar, but would want an option to go back to the list of books at any time. The following trivial example correctly displays a NavigationSplitView on iPadOS, but results in an empty view on iOS: NavigationStack { NavigationSplitView { List { Text("Element1") Text("Element2") } } detail: { Text("Detail") } } Is there a workaround?

I have been recently getting the following error seemingly randomly, when an event handler of a SwiftUI view accesses a relationship of a SwiftData model the view holds a reference to. I haven't yet found a reliable way of reproducing it: SwiftData/BackingData.swift:866: Fatal error: This model instance was invalidated because its backing data could no longer be found the store. PersistentIdentifier(id: SwiftData.PersistentIdentifier.ID(url: COREDATA_ID_URL), implementation: SwiftData.PersistentIdentifierImplementation) What could cause this error? Could you suggest me a workaround?
