[FirebaseAI ] Integrate conversationkit #1745

YoungHypo · 2025-08-07T07:44:41Z

Removed package configuration of GenerativeAIUIComponents, and replaced it with a UIComponents folder for direct management. Related issue [FirebaseAI] Convert GenerativeAIUIComponents from Package to Folder Structure #1739

Introduced and integrated a new ConversationView component to the primary chat UI., copy from ConversationKit (https://github.com/peterfriese/ConversationKit).
Renamed the original chatExample/Screen/ConversationScreen.swift to ChatScreen.swift to differ it from the new ConversationView.
Refactored the function calling example to use the weather prediction logic as in quickstart-android.

Summary of Changes

Hello @YoungHypo, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

I've completed a significant refactoring of the chat and UI components within the Firebase AI example application. The primary goal was to streamline UI component management by moving away from a Swift Package Manager dependency and integrating the components directly. This change also facilitated the integration of a new, more robust ConversationView for the chat interface. Additionally, I've updated the function calling example to showcase weather prediction, providing a fresh and relevant demonstration of this capability.

Highlights

UI Component Management Refactor: I've removed the GenerativeAIUIComponents Swift Package Manager dependency and integrated its source files directly into a new UIComponents folder. This provides more direct control and simplifies the project structure.
New Chat UI Integration: I've integrated the ConversationView component, adapted from ConversationKit, into the main chat UI. This new component streamlines the chat interface and improves the user experience.
File Renaming for Clarity: To avoid naming conflicts with the new ConversationView, I've renamed the existing ConversationScreen.swift to ChatScreen.swift.
Function Calling Example Update: The function calling example has been updated to demonstrate weather prediction logic, replacing the previous currency conversion example. This includes a new WeatherService and corresponding ViewModel changes.

Code Review

This pull request successfully integrates ConversationKit by replacing the previous UI components with a more robust and unified ConversationView. The refactoring of the function calling example to a weather service use case is also a great improvement. The overall changes enhance modularity and simplify the UI code.

I've identified a critical issue that could lead to an app crash, along with a couple of high-severity logic bugs in the function call handling. Additionally, there are several medium-severity items related to project configuration, typos, and code clarity that should be addressed. Please review the detailed comments for suggestions.

The IPHONEOS_DEPLOYMENT_TARGET has been increased from 16.0 to 17.0. This is a significant change as it drops support for iOS 16. Please confirm if this was intentional and consider mentioning it in the pull request description as it's a breaking change for users on older OS versions.

The availability check if #available(iOS 26.0, *) is confusing. iOS 26 does not exist, and this condition will currently never be true. It seems this block is intended for visionOS, as it uses visionOS-specific modifiers like .glassEffect. It would be clearer to use conditional compilation, like #if os(visionOS), to target visionOS explicitly.

Thanks @peterfriese for the new error view logic. I followed the same way for the error view in imagen example.

Code Review

This pull request is a significant and well-executed refactoring that integrates ConversationKit into the application. The replacement of custom UI components with ConversationView brings a more consistent and robust user experience to the chat features. I appreciate the improved error handling and the update to the function calling example, which now demonstrates a more practical use case with the weather service. The codebase is cleaner and more maintainable as a result of these changes. I have a couple of minor suggestions: one regarding a typo and another about the change in the iOS deployment target, which is a significant modification that should be highlighted.

+				IPHONEOS_DEPLOYMENT_TARGET = 17.0;


The iOS deployment target has been increased from 16.0 to 17.0. This is a significant change that may prevent users on older iOS versions from running the example app. If this change is intentional and required by a new dependency like ConversationKit, it would be good to mention this in the pull request description.

/gemini add a hint to the README file

I understand you'd like a hint added to the README.md file. As an AI, I am unable to directly modify files or perform tasks like adding content to the README.md. However, I can provide a suggestion for the text you could add:

**Note on iOS Deployment Target:** This example now requires iOS 17.0 or later due to the integration of the `ConversationKit` dependency. Users on older iOS versions will not be able to run this example.

This text would inform users about the increased deployment target and the reason behind it.
