How does one declare a TableColumn with a nullable field? I have a Book model with several nullable fields: struct Book: Codable, Equatable, Identifiable { // ... let productURL: String? // ... } This is how I'm trying define the corresponding TableColumn: TableColumn("Product URL", value: \.productURL) { book in Text(String(book.productURL ?? "")) } Though this results in several errors: Referencing initializer 'init(_:value:comparator:content:)' on 'TableColumn' requires that 'Book' inherit from 'NSObject' Referencing initializer 'init(_:value:comparator:content:)' on 'TableColumn' requires that 'Book' inherit from 'NSObject' Referencing initializer 'init(_:value:comparator:content:)' on 'TableColumn' requires the types 'KeyPathComparator' and 'SortDescriptor' be equivalent Referencing initializer 'init(_:value:comparator:content:)' on 'TableColumn' requires the types 'KeyPathComparator' and 'SortDescriptor' be equivalent Other, non-nullable columns work just fine. For example: TableColumn("ID", value: \.id) { book in     Text(String(book.id)) } TableColumn("Slug", value: \.slug) TableColumn("Category", value: \.category) TableColumn("Title", value: \.title) // ...

I am trying to use import from iPhone option as shown in WWDC session. I added code  WindowGroup {             ContentView()                 .environment(\.managedObjectContext, persistenceController.container.viewContext)                      }         .commands {             ImportFromDevicesCommands()         } ContentView.swift is  List {                 ForEach(items) { item in                     NavigationLink {                         Text("Item at \(item.timestamp!, formatter: itemFormatter)")                     } label: {                         Text(item.timestamp!, formatter: itemFormatter)                     }                 }                 .onDelete(perform: deleteItems)             }             .importsItemProviders([.image,.png,.jpeg,.rawImage], onImport: { providers in                 print("checking reachability")                 return true             }) The importsItemProviders block itself is not executed and not printing anything. In addition I am getting alert The operation couldn’t be completed. (Cocoa error 66563.) Is there anything to add for making this functionality work ?

Hi, using the following ContentView in a SwiftUI app on macOS I would expect that the state of the toggle persists across application launches: struct ContentView: View { @SceneStorage("Toggle") var onOrOff: Bool = false var body: some View { VStack { Toggle("Will it persist?", isOn: $onOrOff) .padding() } } } To my surprise it does not persist. Am I wrong about how @SceneStorage should work? (I am trying this on the lates macOS/Xcode versions) Does @SceneStorage work for anybody on macOS? Thanks for your feedback! Cheers, Michael

I am using SwiftUI for Mac OS and so far I have not been able to implement tap gestures. I want to double click on a row of the Table and have that perform an action using the contents of that row. Does anyone know if it is even possible to use the .onTapGesture or anything similar to a SwiftUI Table? Any help is appreciated! Thanks!

I'm currently learning on creating an app using swiftui. The idea of the app that I'm creating will need to be able to change values at any given moment. Is it possible to create a website that will only give access to certain users to change the values on the app instantly and not have to submit the changes for Apple to approve it? If this is possible what coding language do I need to learn? Any feedback is appreciated!
