Pokedex SwiftUI

A SwiftUI Pokédex app built to practice modern iOS architecture, networking, state management, pagination, and testability.

This project uses the public PokéAPI to fetch Pokémon, display them in a searchable list, support infinite scrolling, and show a detail screen with additional Pokémon information.

Overview

The goal of this project was to build a clean SwiftUI app while reinforcing production-style iOS patterns:

• MVVM architecture
• SwiftUI List with reusable row views
• Modern Observation using @Observable
• async/await networking with URLSession
• Protocol-based dependency injection
• Pagination / infinite scrolling
• Search with .searchable
• JSON decoding with Decodable
• Basic unit tests for models and view model behavior

Features

• Fetches Pokémon from the PokéAPI
• Displays Pokémon in a SwiftUI List
• Custom row views with sprite images
• Detail screen for each Pokémon
• Searchable list using .searchable
• Infinite scrolling with paginated API requests
• Loading states for initial load and pagination
• Error handling for failed network requests
• Protocol-based API client for easier testing
• Unit tests using Swift Testing

Architecture

The app follows a lightweight MVVM structure.
