Hello. See the code below. struct ContentView: View { var body: some View { TabView { VehicleTab() .tabItem({ Label("Vehicles", systemImage: "car.fill")}) .modelContainer(for: Vehicle.self) TransactionsTab() .tabItem { Label("Transactions", systemImage: "dollarsign") } .modelContainer(for: Transaction.self) } } } Using the .modelContainer() in this way seems to be causing some issue. I was under the assumption that this would just create a container for each view. I get the error below in this configuration. If I comment out either one of the .modelContainer() modifiers, it works fine. Query encountered an error: Error Domain=NSCocoaErrorDomain Code=256 "The file “default.store” couldn’t be opened." Are you not able to do what I'm doing? Is there a way to have two separate containers?

I've been trying to setup a successful migration, but it keeps failing with this error: NSCloudKitMirroringDelegate are not reusable and should have a lifecycle tied to a given instance of NSPersistentStore. I can't find any information about this online. I added breakpoints throughout the code in willMigrate, and it originally failed on this line: try? context.save() I removed that, and it still failed. After I reload the app, it doesn't run the migration again and the app loads successfully. I figured since it crashed, it would keep trying, but I guess not. Here's how my migration is setup. enum MigrationV1ToV2: SchemaMigrationPlan { static var schemas: [any VersionedSchema.Type] { [SchemaV1.self, SchemaV2.self] } static var stages: [MigrationStage] { [stage] } static let stage = MigrationStage.custom( fromVersion: SchemaV1.self, toVersion: SchemaV2.self, willMigrate: { context in // Get cycles let cycles = try? context.fetch(FetchDescriptor<SchemaV1.Cycle>()) if let cycles { for cycle in cycles { // Create new recurring objects based on what's in the cycle for income in cycle.income { let recurring = SchemaV2.Recurring(name: income.name, frequency: income.frequency, kind: .income) recurring.addAmount(.init(date: cycle.startDate, amount: income.amount)) context.insert(recurring) } for expense in cycle.expenses { let recurring = SchemaV2.Recurring(name: expense.name, frequency: expense.frequency, kind: .expense) recurring.addAmount(.init(date: cycle.startDate, amount: expense.amount)) context.insert(recurring) } for savings in cycle.savings { let recurring = SchemaV2.Recurring(name: savings.name, frequency: savings.frequency, kind: .savings) recurring.addAmount(.init(date: cycle.startDate, amount: savings.amount)) context.insert(recurring) } for investment in cycle.investments { let recurring = SchemaV2.Recurring(name: investment.name, frequency: investment.frequency, kind: .investment) recurring.addAmount(.init(date: cycle.startDate, amount: investment.amount)) context.insert(recurring) } } //try? context.save() } else { print("The cycles were not able to be fetched.") } }, didMigrate: { context in // Get new recurring objects let newRecurring = try? context.fetch(FetchDescriptor<SchemaV2.Recurring>()) if let newRecurring { for recurring in newRecurring { // Get all recurring with the same name and kind let sameName = newRecurring.filter({ $0.name == recurring.name && $0.kind == recurring.kind }) // Add amount history to recurring object, and then remove matching for match in sameName { recurring.amountHistory.append(contentsOf: match.amountHistory) context.delete(match) } } //try? context.save() } else { print("The new recurring objects could not be fetched.") } } ) } Here's is my modelContainer in the app file. There is a fatal error occurring here that's crashing the app. var sharedModelContainer: ModelContainer = { let schema = Schema(versionedSchema: SchemaV2.self) let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false) do { return try ModelContainer( for: schema, migrationPlan: MigrationV1ToV2.self, configurations: [modelConfiguration] ) } catch { fatalError("Could not create ModelContainer: \(error)") } }() Does anyone have any suggestions for this? EDIT: I found this error in the console that may be relevant. BUG IN CLIENT OF CLOUDKIT: Registering a handler for a CKScheduler activity identifier that has already been registered (com.apple.coredata.cloudkit.activity.export.8F7A1261-4324-40B4-B041-886DF36FBF0A). CloudKit setup failed because it couldn't register a handler for the export activity. There is another instance of this persistent store actively syncing with CloudKit in this process. And here is the fatal error Fatal error: Could not create ModelContainer: SwiftDataError(_error: SwiftData.SwiftDataError._Error.loadIssueModelContainer, _explanation: nil)

The deletion is working, but it does not refresh the view. This is similar to a question I asked previously but I started a new test project to try and work this out. @Model class Transaction { var timestamp: Date var note: String @Relationship(deleteRule: .cascade) var items: [Item]? init(timestamp: Date, note: String, items: [Item]? = nil) { self.timestamp = timestamp self.note = note self.items = items } func getModifierCount() -> Int { guard let items = items else { return 0 } return items.reduce(0, {result, item in result + (item.modifiers?.count ?? 0) }) } } @Model class Item { var timestamp: Date var note: String @Relationship(deleteRule: .nullify) var transaction: Transaction? @Relationship(deleteRule: .noAction) var modifiers: [Modifier]? init(timestamp: Date, note: String, transaction: Transaction? = nil, modifiers: [Modifier]? = nil) { self.timestamp = timestamp self.note = note self.transaction = transaction self.modifiers = modifiers } } @Model class Modifier { var timestamp: Date var value: Double @Relationship(deleteRule: .nullify) var items: [Item]? init(timestamp: Date, value: Double, items: [Item]? = nil) { self.timestamp = timestamp self.value = value self.items = items } } struct ContentView: View { @Environment(\.modelContext) private var context @Query private var items: [Item] @Query private var transactions: [Transaction] @Query private var modifiers: [Modifier] @State private var addItem = false @State private var addTransaction = false var body: some View { NavigationStack { List { Section(content: { ForEach(items) { item in LabeledText(label: item.timestamp.formatAsString(), value: .int(item.modifiers?.count ?? -1)) } .onDelete(perform: { indexSet in withAnimation { for index in indexSet { context.delete(items[index]) } } }) }, header: { LabeledView(label: "Items", view: { Button("", systemImage: "plus", action: {}) }) }) Section(content: { ForEach(modifiers) { modifier in LabeledText(label: modifier.timestamp.formatAsString(), value: .currency(modifier.value)) } .onDelete(perform: { indexSet in indexSet.forEach { index in context.delete(modifiers[index]) } }) }, header: { LabeledView(label: "Modifiers", view: { Button("", systemImage: "plus", action: {}) }) }) Section(content: { ForEach(transactions) { transaction in LabeledText(label: transaction.note, value: .int(transaction.getModifierCount())) } .onDelete(perform: { indexSet in withAnimation { for index in indexSet { context.delete(transactions[index]) } } }) }, header: { LabeledView(label: "Transactions", view: { Button("", systemImage: "plus", action: {addTransaction.toggle()}) }) }) } .navigationTitle("Testing") .sheet(isPresented: $addTransaction, content: { TransactionEditor() }) } } } } Here's the scenario. Create a transaction with 1 item. That item will contain 1 modifier. ContentView will display Items, Modifiers, and Transactions. For Item, it will display the date and how many modifiers it has. Modifier will display the date and its value. Transactions will display a date and how many modifiers are contained inside of its items. When I delete a modifier, in this case the only one that exist, I should see the count update to 0 for both the Item and the Transaction. This is not happening unless I close the application and reopen it. If I do that, it's updated to 0. I tried to add an ID variable to the view and change it to force a refresh, but it's not updating. This issue also seems to be only with this many to many relationship. Previously, I only had the Transaction and Item models. Deleting an Item would correctly update Transaction, but that was a one to many relationship. I would like for Modifier to have a many to many relationship with Items, so they can be reused. Why is deleting a modifier not updating the items correctly? Why is this not refreshing the view? How can I resolve this issue?

It seems like this may have been an issue for a while based on what I've seen, but I have added a toolbar item to a textfield keyboard and it doesn't show. The only way I can get it to show is by opening the keyboard, typing something, closing the keyboard, and then reopening it. Anyone have a workaround for this? It's like Apple purposely wants to make it difficult to close the keyboard. TextField("Something here...", text: $text, axis: .vertical) .multilineTextAlignment(.leading) .toolbar { ToolbarItemGroup(placement: .keyboard, content: { Button("Close") { } }) }
