Sharing Chatbot Functionality with other apps

Our first-look chatbot, which we implemented, is not just powerful; we can be generous and share this functionality with other apps. By using Apple’s AppIntent framework, we can quickly achieve this.

Source Code

Exposing App Functionality

import SwiftUI
import AppIntents

struct SendToChatbotIntent: AppIntent {

    static let title: LocalizedStringResource = "Send to Chatbot"
    
    static let description = IntentDescription("Testing")
    
    static let openAppWhenRun: Bool = false
    
    @Parameter(title: "To Chatbot", requestValueDialog: "What to send?")
    var target: String
    
    @MainActor
    func perform() async throws -> some IntentResult & ReturnsValue<String> {
        let answer = await AppleFoundationModelViewModel.shared.ask(prompt: target) ?? "No response"
        return .result(value: answer)
    }
}

Prepare App for Activation via AppIntent

We need to be able to call our chat engine from AppIntent. We will create an app shared object to do this.

class AppleFoundationModelViewModel {
    
    static let shared = AppleFoundationModelViewModel(instruction:
"""
First display an emoji that is appropriate to represent the whole given text.
Then give analysis on a given input and summarise it into one short sentence with less than 30 words. 
Append at the end as a new line the tone or mood of the text. 
Append at the end as a new line bullet points of people found in the given input.
"""
    )
    ...

}

Now from an AppIntent, we can access our chatbox engine, for example:

let answer = await AppleFoundationModelViewModel.shared.ask(prompt: someText)

That’s it!

Build and deploy to a device and now other apps on the device can access to Chatbot’s functionality.

Next post we will see how to hook this up.

Stay tune.
