Hi, I'm new to Swift development and encountering an issue that I believe may be due to an error on my part. I have two questions regarding the following code: import AppIntents import SwiftUI import SwiftData @available(iOS 17.0, *) struct CopiarEventoIntent: AppIntent { @Environment(\.modelContext) private var context @Parameter(title: "Nome do Evento") var name: String @Parameter(title: "Data Inicial") var datai: Date @Parameter(title: "Data Final") var dataf: Date @Parameter(title: "Tipo de Evento") var tipo: String @Parameter(title: "Endereço") var endereco: String @Parameter(title: "Lembrete") var reminder: Bool static var title: LocalizedStringResource = "Adicionar Eventos" static var description = IntentDescription("Copiar Eventos e alterar datas", resultValueName: "Resultado") @MainActor func perform() async throws -> some IntentResult & ProvidesDialog { let calData = CalData(title: name, datei: datai, datef: dataf, tipo: tipo, endereco: endereco,reminder: reminder) context.insert(calData) return .result(dialog: "Evento copiado com sucesso!") } } @available(iOS 15.0, *) struct AppShortcuts: AppShortcutsProvider { static var appShortcuts: [AppShortcut] { AppShortcut( intent: CopiarEventoIntent(), phrases: [ "Copiar Evento" ], shortTitle: "Copiar Evento", systemImageName: "square.and.arrow.down" ) } } @available(iOS 15.0, *) struct ShortcutSelectionView: View { @Environment(\.modelContext) private var context @Query(sort: \CalData.title) private var caldatas: [CalData] @State private var selectedEvent: CalData? var body: some View { List(caldatas, id: \.self) { eventData in Button(action: { selectedEvent = eventData handleEventSelection() }) { Text(eventData.title) } } } private func handleEventSelection() { guard selectedEvent != nil else { return } } } When I run the shortcut, gives me the following error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Cannot insert 'CalData' in this managed object context because it is not found in the associated managed object model. I attempted to save this using SwiftData with the following model: import SwiftData @Model class CalData { var title : String var datei : Date var datef : Date var tipo : String var endereco : String @Relationship(deleteRule: .cascade) var caldataval = [CalDataVal]() var reminder: Bool = false init(title:String, datei:Date, datef:Date, tipo:String, endereco:String, reminder:Bool){ self.title = title self.datei = datei self.datef = datef self.tipo = tipo self.endereco = endereco self.reminder = reminder } } As for the second question, how can I add a parameter that can have multiple values to save them to EventDataVal, resembling a one-to-many relationship: import SwiftData @Model class CalDataVal { var name : String var value : Double init(name:String, value:Double){ self.name = name self.value = value } } Thanks in advanced
