Hi team, I'm running into the following issue, for which I don't seem to find a good solution. I would like to be able to drag and drop items from a view into empty space to open a new window that displays detailed information about this item. Now, I know something similar has been flagged already in this post (FB13545880: Support drag and drop to create a new window on visionOS) HOWEVER, all this does, is launch the App again with the SAME WindowGroup and display ContentView in a different state (show a selected product e.g.). What I would like to do, is instead launch ONLY the new WindowGroup, without a new instance of ContentView. This is the closest I got so far. It opens the desired window, but in addition it also displays the ContentView WindowGroup WindowGroup { ContentView() .onContinueUserActivity(Activity.openWindow, perform: handleOpenDetail) } WindowGroup(id: "Detail View", for: Reminder.ID.self) { $reminderId in ReminderDetailView(reminderId: reminderId! ) } .onDrag({ let userActivity = NSUserActivity(activityType: Activity.openWindow) let localizedString = NSLocalizedString("DroppedReminterTitle", comment: "Activity title with reminder name") userActivity.title = String(format: localizedString, reminder.title) userActivity.targetContentIdentifier = "\(reminder.id)" try? userActivity.setTypedPayload(reminder.id) // When setting the identifier let encoder = JSONEncoder() if let jsonData = try? encoder.encode(reminder.persistentModelID), let jsonString = String(data: jsonData, encoding: .utf8) { userActivity.userInfo = ["id": jsonString] } return NSItemProvider(object: userActivity) }) func handleOpenDetail(_ userActivity: NSUserActivity) { guard let idString = userActivity.userInfo?["id"] as? String else { print("Invalid or missing identifier in user activity") return } if let jsonData = idString.data(using: .utf8) { do { let decoder = JSONDecoder() let persistentID = try decoder.decode(PersistentIdentifier.self, from: jsonData) openWindow(id: "Detail View", value: persistentID) } catch { print("Failed to decode PersistentIdentifier: \(error)") } } else { print("Failed to convert string to data") } }

I have encountered an issue that when using a ModelActor to sync data in the background, the app will crash if one of the operations is to remove a PersistentModel from the context. This is running on the latest beta of Xcode 16 with visionOS 1.2 as target and in Swift 6 language mode. The code is being executed in a ModelActor. The error is first thrown by: #5 0x00000001c3223280 in PersistentModel.getValue<τ_0_0>(forKey:) () Thread 1: Fatal error: Context is missing for Optional(SwiftData.PersistentIdentifier(id: SwiftData.PersistentIdentifier.ID(url: x-coredata://97AA86BC-475D-4509-9004-D1182ABA1922/Reminder/p303), implementation: SwiftData.PersistentIdentifierImplementation)) func globalSync() async { await fetchAndSyncFolders() let result = await fetchReminders() switch result { case .success(let ekReminders): var localReminders = (try? await fetch(FetchDescriptor<Reminder>())) ?? [] // Handle local reminders with nil ekReminderID by creating new EKReminders for them for reminder in localReminders { if reminder.ekReminderID == nil { await self.createEkReminder(reminder: reminder) } } // Re-fetch local reminders to include newly created EKReminderIDs localReminders = (try? await fetch(FetchDescriptor<Reminder>())) ?? [] var localReminderDict = [String: Reminder]() for reminder in localReminders { if let ekReminderID = reminder.ekReminderID { if let existingReminder = localReminderDict[ekReminderID] { self.delete(model: existingReminder) } else { localReminderDict[ekReminderID] = reminder } } } let ekReminderDict = createReminderLookup(byID: ekReminders) await self.syncReminders(localReminders: Array(localReminderDict.values), localReminderDict: localReminderDict, ekReminderDict: ekReminderDict) // Merge duplicates await self.mergeDuplicates(localReminders: localReminders) save() case .failure(let error): print("Failed to fetch reminders: \(error.localizedDescription)") } }
