SwiftUI Messaging App with Google Generative AI

Overview

This SwiftUI messaging app demonstrates real-time messaging capabilities with integration of Google's Generative AI for generating smart replies. Users can interact with the app by sending messages and receiving AI-generated responses. The app features a dynamic user interface and leverages Google's GenerativeModel API for natural language processing.

Features

• Real-time Messaging: Send messages and receive AI-generated responses in real time.
• Dynamic UI: Fluid and responsive user interface using SwiftUI.
• AI Integration: Utilizes Google's GenerativeModel API for smart and context-aware replies.
• Image Support: Option to send an image along with the message to get AI-generated responses considering the image content.

Technologies Used

• SwiftUI: A modern UI toolkit for building iOS applications.
• Google Generative AI: Advanced AI for natural language processing and content generation.
• Combine: A framework for handling asynchronous events in Swift.
• UIKit: Used for integrating the image picker.

Setup Instructions

Prerequisites

• Xcode: Ensure you have the latest version of Xcode installed (minimum version 12.0).
• Cocoapods: Ensure you have Cocoapods installed for dependency management.
• Google API Key: Obtain an API key from Google Cloud for accessing the GenerativeModel API.

Installation Steps

1. Clone the Repository:

   git clone https://github.com/msnabiel/GeminiChat-iOS.git
   cd GeminiChat-iOS

2. Install Dependencies: Make sure to navigate to the project directory and install necessary dependencies.

   pod install

3. Open the Project: Open the Xcode workspace:

   open GeminiChat-iOS.xcworkspace

4. Configure API Key:

   • Locate the ContentView.swift file.
   • Replace the placeholder API key with your actual API key from Google Cloud:

     let apiKey = "YOUR_GOOGLE_API_KEY"

5. Run the Project: Select a target device or simulator in Xcode and click the Run button to build and run the app.

API Key Configuration

To use Google's Generative AI, you'll need an API key. Follow these steps to obtain one:

1. Go to Google Cloud Console: Google Cloud Console

2. Create a New Project: If you don't have an existing project, create a new one.

3. Enable the API: Search for "Generative AI API" in the API library and enable it for your project.

4. Create API Credentials:

   • Go to the Credentials page.
   • Click on Create credentials and select API key.
   • Copy the generated API key and replace the placeholder in your project.

Usage Instructions

1. Sending a Message:

   • Type a message into the text field at the bottom of the screen.
   • Click the send button (green arrow) to send the message and receive an AI-generated response.

2. Sending an Image:

   • Tap the camera icon to select an image from your device.
   • The AI will generate a response based on the image and the accompanying text.

Project Structure

• ContentView.swift: The main SwiftUI view containing the UI and logic for messaging.
• ImagePicker.swift: A helper file for selecting images from the photo library.
• Message.swift: A model representing a message, including its content and sender.
• GoogleGenerativeAI: A framework for integrating Google's Generative AI API.

Known Issues

• Limited Token Length: The AI response is limited by the maximum token count set in the API configuration.
• Image Response Delay: Processing images for AI response may take longer than text messages.

Future Enhancements

• Push Notifications: Integrate push notifications for real-time message updates.
• User Authentication: Add user authentication for personalized messaging experience.
• Enhanced UI: Further improve the UI for a more engaging user experience.
