AI Ask with Multiple Tool Function Callbacks

See more AI Examples

This example demonstrates asking a two-part question that should cause the AI to respond with two tool call requests. Swift

func chilkatTest() {
    var success: Bool = false

    //  ----------------------------------------------------------------------------------
    //  The Javascript file loaded here is shown at the bottom of this page.
    //  -----------------------------------------------------------------------------------

    //  Load JavaScript containing the tool functions.
    let sbJs = CkoStringBuilder()!
    success = sbJs.loadFile(path: "qa_data/js_tools/toolset_6.js", charset: "utf-8")
    if success == false {
        print("\(sbJs.lastErrorText!)")
        return
    }

    let ai = CkoAi()!

    //  Register the tools that will be made available to the AI.
    var evalOnly: Bool = false
    var allowAllKeyword: Bool = true
    ai.registerJsTools(sb: sbJs, evalOnly: evalOnly, allowAllKeyword: allowAllKeyword)

    //  The provider can be "openai", "google", "claude", "grok", "mistral", "custom", etc.
    ai.provider = "openai"
    //  Use your provider's API key.
    ai.apiKey = "MY_API_KEY"
    //  Choose a model.
    ai.model = "gpt-5.6-luna"

    //  Tool function calling must always occur within a conversation.
    var conversation_name: String? = "example_convo"
    var sysMessage: String? = "You are a helpful assistant"
    var devMessage: String? = "Respond with markdown"
    ai.newConvo(name: conversation_name, sysMsg: sysMessage, devMsg: devMessage)

    //  Provide inputs
    ai.inputAddText(text: "What is my horoscope? I am an Aquarius.  Also, what's the weather in Chicago?")

    //  Send inputs, tool functions, etc. and ask for a "text" response.
    //  If the AI responds with tool calls, Chilkat automatically handles them by calling your JavaScript
    //  tool functions as directed by the AI, and sending results back to the AI until the final
    //  response is received.
    success = ai.ask(outputType: "text")
    if success == false {
        print("\(ai.lastErrorText!)")
        return
    }

    //  Get the AI response.
    let sbResponse = CkoStringBuilder()!
    ai.getOutputTextSb(sb: sbResponse)
    print("\(sbResponse.getAsString()!)")

}
