Overview

AudioFetchGPT is an iOS application designed to interact with ChatGPT, allowing users to download and manage audio content from conversations. The app provides a web interface to ChatGPT, audio playback capabilities, and a download management system.

Key Features

1. Web Interface: Integrates a WebView to interact with ChatGPT.
2. Audio Download: Captures and downloads audio content from ChatGPT conversations.
3. Audio Playback: Allows users to play, pause, and seek through downloaded audio files.
4. Download Management: Provides a list view of downloaded audio files with editing and deletion capabilities.
5. Search Functionality: Enables users to search within the ChatGPT interface.

Main Components

WebView

• WebView.swift: UIViewRepresentable struct that wraps a WKWebView for displaying ChatGPT.
• WebViewModel.swift: Manages the WebView's configuration and JavaScript interactions.
• ScriptMessageHandler.swift: Handles messages from JavaScript for audio download.

Audio Management

• AudioManager.swift: Central manager for audio playback and control.
• AudioPlayerManager.swift: Manages the AVAudioPlayer for actual audio playback.
• AudioProgressManager.swift: Tracks and stores progress for each audio file.
• AudioTimerManager.swift: Manages timers for updating audio progress.

Models

• DownloadedAudio.swift: Represents a downloaded audio file.
• DownloadedAudios.swift: Manages the collection of downloaded audio files.

Views

• ContentView.swift: Main view of the application.
• DownloadListView.swift: Displays the list of downloaded audio files.
• AudioRowView.swift: Individual row view for each audio file in the list.
• AudioDetailsView.swift: Detailed view for a single audio file.

Key Functionalities

1. Audio Download: The app injects a JavaScript script into the WebView to intercept audio synthesis requests. When an audio file is generated, it's captured and downloaded to the device.

2. Audio Playback: Users can play, pause, and seek through downloaded audio files. The app supports background audio and integrates with the iOS audio session for system-wide audio controls.

3. Download Management: Users can view, rename, and delete downloaded audio files. The app maintains a list of downloads and their metadata.

4. Web Interaction: The app provides a custom interface for interacting with ChatGPT, including search functionality and the ability to navigate to specific messages.

5. State Management: The app uses SwiftUI's state management features (@State, @ObservedObject, @EnvironmentObject) to maintain and update the UI based on user interactions and audio playback status.
