# isResponding

A Boolean value that indicates a response is being generated.

## Declaration

```swift
final var isResponding: Bool { get }
```

## Mentioned in

Generating content and performing tasks with Foundation Models

## Discussion

Discussion important: You should not call any of the respond methods while this property is true. 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     } }
