🏡 Real Estate Finder App (UIKit + Core Data)

An iOS application that allows users to search, view, and save real estate listings using Zillow’s REST API and Core Data for persistence.
Built entirely with UIKit and programmatic Auto Layout, following the MVC architecture.
Developed as part of an academic project at Seneca Polytechnic.

⚠️ Note: The app originally integrated Zillow’s RapidAPI for live property data.
As of 2025, the public API endpoint is deprecated, so real-time search is no longer active.
However, the project fully demonstrates API request handling, JSON decoding, and Core Data integration.

🚀 Features

• 🔍 Property Search — Browse real estate listings with filters for location, price, beds, and baths
• 🏠 Property Details — View images, prices, and descriptions of individual listings
• ❤️ Favorites Management — Save and view favorite properties using Core Data persistence

🧩 Architecture Overview

The app follows the MVC (Model–View–Controller) pattern for clarity and scalability.

Models

• PropertyModel.swift — Defines the structure for API-decoded property data
• Core Data Entities:
  • User and FavoriteProperty (with relationships and attributes)
  • Persistence.swift handles the Core Data stack

Views

• SearchPropertyCell.swift — Displays search results dynamically with async image loading
• FavoritesTableViewCell.swift — Shows saved favorites in a card-like layout

ViewControllers

• SearchZillowViewController.swift — Handles API requests and search logic
• FavoritesViewController.swift — Displays and manages saved Core Data favorites
• LoginViewController.swift / SignUpViewController.swift — Handles user authentication
• MainTabBarController.swift / LogoutPlaceholderViewController.swift — Manages main navigation flow
• WelcomeViewController.swift — Initial screen for first-time users

🧠 Key Technical Highlights

• Frameworks: UIKit, Core Data, Foundation
• Architecture: MVC
• Networking: REST API integration (Zillow’s RapidAPI, using URLSession)
• Persistence: Core Data (CRUD operations and entity relationships)
• UI: Fully programmatic layout with Auto Layout constraints
• Authentication: Core Data–based local login and registration
• Error Handling: Alerts, predicates, and optional unwrapping for safe logic execution
