It has two modules: AssetsList and AssetDetails. The list of cryptocurrencies is loaded in batches.

• Layered Architecture
• MVVM
• Flow coordinator
• Dependency Injection, DIContainer
• Data Binding using the lightweight Observable<T>
• Closure-based delegation using the lightweight Event<T>
• Reusable data sources

• async/await with the existing Infrastructure remaining unchanged
• SharedEvents - a NotificationCenter-like component
• Currency conversion service - for displaying asset prices in different currencies (USD, EUR, etc.)
• Configurable use of UserDefaults or SwiftData example
• Cached Task to avoid making duplicate network requests
• Advanced using of Codable
• Localization
• Unit tests

• SwiftEvents - The easiest way to implement data binding and notifications. Includes Event<T> and Observable<T>. Has a thread-safe version.
• URLSessionAdapter - A Codable wrapper around URLSession for networking.
• Toast-Swift - A Swift extension that adds toast notifications to the UIView object class.
• UAObfuscatedString - A simple category to hide sensitive strings from appearing in your binary.
