This seems to work: NotificationCenter.default.notifications(named: Notification.Name.NSManagedObjectContextDidSave)

This works even better: NotificationCenter.default.notifications(named: Notification.Name.NSManagedObjectContextObjectsDidChange) Looks like a bug needs filed here. Appears that the NSManagedObjectContextObjectsDidChange is likely what ModelContext.didSave should be triggering, as the object in the notification is the ModelContext instance: (lldb) po notif ▿ name = NSObjectsChangedInManagingContextNotification, object = Optional(SwiftData.ModelContext), userInfo = Optional([AnyHashable("updated"): Set([SwiftData.ModelContext.AnyPersistentObject(boxed: Redacted.Redacted)])]) - name : "NSObjectsChangedInManagingContextNotification" ▿ object : <ModelContext: 0x281632e50> ▿ userInfo : 1 element ▿ 0 : 2 elements ▿ key : AnyHashable("updated") - value : "updated" ▿ value : 1 element ▿ 0 : AnyPersistentObject ▿ boxed : <Redacted: 0x280e545a0>
