Why is "Go small with embedded Swift" still not available, despite the fact all the other WWDC24 Tuesday session videos are?

I just saw the new SwiftData updates, including the DataStore API. I’m wondering if, in the case of a shared remote datastore, it is possible to enable updates to the model context from the datastore without the model context explicitly requesting them (e.g., through database listeners). If I’m not mistaken, when you use CloudKit with SwiftData, this happens, right?

I have this sample code: struct Item: Identifiable { var id = UUID() var name: String? } struct ItemTable: View { let items: [Item] var body: some View { Table(items) { TableColumn("Name", value: \.name) } } } I get the following error: Key path value type 'String?' cannot be converted to contextual type 'String' I can solve using \.name!, but I'd like to give a default value instead (something like \.name ?? "default"). How can I achieve this?
