Feeder - RSS Post Viewer

A high-performance iOS news reader application built with a reactive MVI-C architecture, featuring real-time data synchronization via Firebase and a custom SwiftUI interface.

📝 Project Overview

Feeder is designed to provide a seamless news browsing experience. It fetches structured data from Firebase, handles local processing (such as sorting and truncation), and presents it through a declarative UI.

Key Features:

• Post Feed:
  • Dynamic sorting by Date and Rating (processed locally).
  • Smart text truncation: displays only 2 lines of text with a "Read more" toggle for expanding the summary in-line.
  • Maintains server-defined default order until user interaction.
• Detailed View:
  • Full post content rendering.
  • Integrated image gallery with asynchronous loading and caching via NukeUI.
  • Relative timestamps (e.g., "6 years ago") for better readability.
• Core Logic:
  • Offline Support: Data is cached to remain available without an active internet connection.
  • Error Handling: Robust navigation and alert logic for missing or deleted posts.

🛠 Tech Stack

• Interface: SwiftUI (Declarative interface).
• Architecture: MVI-C (Model-View-Intent + Coordinator) for strict unidirectional data flow.
• Reactive: Combine (Used for Firebase subscriptions and Store-Reducer communication).
• Backend: Firebase Realtime Database.
• Navigation: UIKit UINavigationController wrapped for SwiftUI to provide native swipe-back gestures and full stack control.
• Image Handling: NukeUI for efficient async image loading and shimmer loading states.

🚀 Installation & Setup

1. Clone the repository:

   git clone https://github.com/nikolay-goncharenko/Feeder_iOS.git

2. Environment Preparation:

   • Ensure you have Xcode 15+ installed.
   • The project uses Swift Package Manager (SPM) to manage dependencies.
   • Key libraries include Nuke (Image loading), Firebase (Backend), and R.swift (Resource management).
   • Xcode will automatically resolve and download these dependencies when you first open the project.

3. Build and Run:

   • Open the Feeder.xcodeproj file.
   • Select a target simulator (e.g., iPhone 17 Pro).
   • Press Cmd + R to build and launch the application.
