# Cryptocurrency Info
[](https://swift.org)
[](https://developer.apple.com/swift/)
[](https://github.com/denissimon/Cryptocurrency-Info/blob/master/LICENSE)
Example iOS app designed using MVVM-C and Layered Architecture. Uses Swift Concurrency.
The app shows cryptocurrency prices and other related info. Built with Messari API.
It has two modules: AssetsList and AssetDetails. The list of cryptocurrencies is loaded in batches.
### Architecture concepts used here
- [Layered Architecture][LayeredArchitectureLink]

- [Dependency Injection][DIContainerLink], DIContainer
- [Data Binding][DataBindingLink] using the lightweight Observable\
- [Closure-based delegation][ClosureBasedDelegationLink] using the lightweight Event\
- [Reusable data sources][DataSourceLink]

### Built with
- [SwiftEvents](https://github.com/denissimon/SwiftEvents) - The easiest way to implement data binding and notifications. Includes Event\ and Observable\. Has a thread-safe version.
- [URLSessionAdapter](https://github.com/denissimon/URLSessionAdapter) - A Codable wrapper around URLSession for networking.
- [Toast-Swift](https://github.com/scalessec/Toast-Swift) - A Swift extension that adds toast notifications to the UIView object class.
- [UAObfuscatedString](https://github.com/UrbanApps/UAObfuscatedString) - A simple category to hide sensitive strings from appearing in your binary.
The dependency manager is [Swift Package Manager](https://www.swift.org/documentation/package-manager/). To update package versions:
