VIPER Architecture Pattern - Swift Concurrency Version

Visually Interesting Planned Easy Roadtrips (VIPER)

This is a Swift concurrency implementation of the VIPER architecture pattern tutorial from Kodeco. The original tutorial used Combine for reactive programming, while this version uses modern Swift concurrency.

Key Differences from Original Tutorial

• Swift Concurrency: Uses async/await instead of Combine's Publisher/Subscriber pattern
• @Observable Macro: Replaces Combine's @Published properties with the new @Observable macro for reactive UI updates
• @MainActor: Ensures UI updates happen on the main thread using the @MainActor macro
• Modern Swift: Leverages Swift 5.9+ features for cleaner, more maintainable code

Architecture Overview

VIPER stands for:

• View: SwiftUI views that display the user interface
• Interactor: Business logic and data manipulation
• Presenter: Coordinates between View and Interactor, handles presentation logic
• Entity: Data models (Trip, Waypoint)
• Router: Navigation and routing between screens

Instructions

• To see pictures, you'll need to get a Pixabay API Key here: https://pixabay.com/accounts/register/?source=signup_button_header
  • Then, paste it into the spot in ImageDataProvider.swift
  • It'll look cool if you choose interesting places for your trip

Features

• Create and manage road trips with waypoints
• Interactive map view showing trip routes
• Image integration with Pixabay API
• Clean VIPER architecture with Swift concurrency
• Persistent data storage using JSON
