SwiftUI iOS App Development: Build a Movie & TV App from Scratch

Project Setup and UI Basics

• 🚀 Blossom Movie app is built from scratch using SwiftUI and Xcode.
• 🏠 The app features a tabbed interface with Home, Upcoming, Search, and Download sections.
• 🏗️ Constants file is created to manage all string literals and icon names, promoting good coding habits.
• 🖼️ The Home View is designed with a dynamic hero title, and placeholder buttons for trailer playback and downloading.
• 🎨 Custom colors, 'Blossom Build Green' and 'Button Text', are added to the Assets catalog for styling.

Horizontal and Vertical Lists

• 🎬 Horizontal List View is created to display rows of movie posters, designed to be reusable for different categories like trending and top-rated.
• 📱 The Home View is enhanced with a scrollable layout containing multiple horizontal lists for trending and top-rated movies and TV shows.
• 📈 Swift Data is introduced for offline storage, allowing users to download and save titles for later viewing.
• ➡️ Vertical List View is implemented to display lists of titles, initially populated with sample data.

API Integration and Data Handling

• 🔑 The Movie Database (TMDB) API is integrated to fetch movie and TV show data.
• 🌐 API Configuration involves storing base URLs and API keys in a JSON file for security and dynamic loading.
• 🛠️ Error Handling is implemented using custom enums (APIConfigError, NetworkError) to gracefully manage issues like missing files or invalid responses.
• 🔄 Data Fetcher class is created to handle network requests, including building URLs and decoding JSON responses using generics.
• 🎬 YouTube API integration is set up to fetch video IDs for trailers, displayed using a YouTubePlayer wrapper.

Navigation and User Interface

• 🧭 Navigation Stack is used for managing navigation flow, allowing users to move between screens.
• 🔍 A Search View is implemented with a grid layout and a dynamic toolbar that can toggle between movie and TV show searches.
• ⌨️ A Search Bar is added using the .searchable modifier, with debouncing implemented to optimize API calls.
• 📱 View Models (SearchViewModel, HomeViewModel) are utilized to manage UI state and data fetching logic, adhering to MVVM principles.
• ➡️ Navigation Links and Navigation Paths are demonstrated for navigating to detail screens and managing navigation history.

Advanced Features and Refinements

• 🗑️ Swift Data is used to implement download functionality, allowing users to save and delete titles.
• 🔄 Duplicate Prevention and Alphabetical Sorting are added to the downloaded titles list for better data management.
• 🐞 Bug Fixing involves addressing navigation issues and improving error display across the app.
• 🎨 UI Enhancements include centering progress views and improving the appearance of error messages.
