Disable buttons and other interactions to prevent users from submitting a second prompt while the model is responding to their first prompt.

struct ShopView: View {
    @State var session = LanguageModelSession()
    @State var joke = ""

    var body: some View {
        Text(joke)
        Button("Generate joke") {
            Task {
                assert(!session.isResponding, "It should not be possible to tap this button while the model is responding")
                joke = try await session.respond(to: "Tell me a joke").content
            }
        }
        .disabled(session.isResponding) // Prevent concurrent calls to respond
    }
}
