Share data

How can I share SwiftData @Model between widget and app?

try this:

static private var sharedModelContainer: ModelContainer = {
    let schema = Schema([
        MyModel.self,
    ])
    let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false)
 
    do {
        return try ModelContainer(for: schema, configurations: [modelConfiguration])
    } catch {
        fatalError("Could not create ModelContainer: \(error)")
    }
}()
 
static var sharedModelContext = ModelContext(Self.sharedModelContainer)
