Current state

The codebase is currently under development, with core features implemented and more being added.

Setup

  1. Get a TMDB API key from themoviedb.org.
  2. Create a Secrets.plist file in the project root with the following content: 
    <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>API_KEY</key>
    <string>your_api_key_here</string>
</dict>
</plist>
  3. Open the project in Xcode and build.

Tech Stack

  • Language: Swift
  • UI Framework: SwiftUI
  • Architecture: MVVM (Model-View-ViewModel)
  • Networking: URLSession
  • JSON Parsing: Codable
  • Image Loading: AsyncImage
  • Asynchronous Programming: Swift Concurrency
  • State Management: @Published, @State, @Binding
  • Dependency Injection: Manual (via init and @EnvironmentObject)
  • UI Components: SwiftUI native components
  • Build System: Xcode
  • Minimum iOS Version: iOS 17.4 (as per current project settings)

Key Features

  1. Browse movies by different categories (popular, upcoming, now playing, top-rated)
  2. Search for movies
  3. View detailed movie information
  4. Mark movies as favorites
  5. Apply filters (genre, release year, minimum rating)
  6. Toggle between light and dark themes
  7. Localization support

Architecture

The app follows the MVVM (Model-View-ViewModel) architecture:

  • Model: Represented by the Movie and MovieResponse structs
  • View: SwiftUI views in various view files
  • ViewModel: NetworkManager manages the app's state and business logic

Data Flow

  1. The NetworkManager fetches data from the TMDB API
  2. Data is then exposed to the UI components via @Published properties
  3. UI components observe these properties and update when the data changes

Networking

The app uses URLSession for network requests. The NetworkManager class handles all API calls and data parsing.

State Management

The app uses SwiftUI's state management tools:

  • @Published for observable object properties
  • @State for view-local state
  • @Binding for passing mutable state to child views
  • @EnvironmentObject for dependency injection

Theming

The app supports dynamic theming with light and dark mode options. The ThemeManager class handles theme selection and application.

Localization

The app supports localization with strings defined in Localizable.strings.
