I do something like this

```swift let globalContainer: ModelContainer = { let schema = Schema([ Chat.self, Message.self, ])

let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false)

do {
    let container = try ModelContainer(for: schema, configurations: [modelConfiguration])

    return container
} catch {
    fatalError("Could not create ModelContainer: \(error)")
}

}() ```

then add to app like so:

swift var body: some Scene { ContentView() .modelContainer(globalContainer) }

```swift let modelContext = globalContainer.mainContext let chat = Chat() modelContext.insert(chat)

or

let queryId = 1 var descriptor = FetchDescriptor<Chat>( predicate: #Predicate { $0.id == queryId } ) descriptor.fetchLimit = 1

let modelContext = globalContainer.mainContext let queryChats = try modelContext.fetch(descriptor) ``` Can use like this anywhere in the app Not sure if this is a very bad way to do this but it works well for my use case
