If your app deploys to iOS 26, macOS 26, or visionOS 26, where this error is unavailable, use an availability check and fall back to LanguageModelSession.GenerationError:

do {
    let response = try await session.respond(to: prompt)
} catch {
    if #available(iOS 27.0, macOS 27.0, visionOS 27.0, *),
        let error = error as? LanguageModelError
    {
        // Handle the error.
    } else if let error = error as? LanguageModelSession.GenerationError {
        // Handle the deprecated error.
    }
}
