Chat demo App: How to fetch function arguments on the view?

[Alexandre Lordelo]

Is your feature request related to a problem? Please describe.
Would be great to be able to fetch function arguments on the view.

Describe the solution you'd like

When defined:

  let weatherFunction = ChatFunctionDeclaration(
            name: "getWeatherData",
            description: "Get the current weather in a given location",
            parameters: .init(
              type: .object,
              properties: [
                "location": .init(type: .string, description: "The city and state, e.g. San Francisco, CA"),
                "degrees": .init(type: .string, description: "The degrees, in celsius. Ex: 10c")

              ],
              required: ["location"]
            )
        )

When prompted "show me the weather in San Francisco"...

Current demo app shows the on the bubble: message.content
Would be great to be able to fetch the property, ex: function.degrees.

This would enable to place specific function properties on tables, graphs, etc...

 var body: some View {
        HStack {
            switch message.role {
            case .assistant:
                Text(message.content)
                    .padding(.horizontal, 16)
                    .padding(.vertical, 12)
                    .background(assistantBackgroundColor)
                    .clipShape(RoundedRectangle(cornerRadius: 16, style: .continuous))
                Spacer(minLength: 24)
            case .user:
                Spacer(minLength: 24)
                Text(message.content)
                    .padding(.horizontal, 16)
                    .padding(.vertical, 12)
                    .foregroundColor(userForegroundColor)
                    .background(userBackgroundColor)
                    .clipShape(RoundedRectangle(cornerRadius: 16, style: .continuous))
            case .function:
              Text(message.content)
                  .font(.footnote.monospaced())
                  .padding(.horizontal, 16)
                  .padding(.vertical, 12)
                  .background(funcBackgroundColor)
                  .clipShape(RoundedRectangle(cornerRadius: 16, style: .continuous))
              Spacer(minLength: 24)
            case .system:
                EmptyView()
            }
        }
    }
