Architecture

MVVM Architecture

In developing CoinCo App, the programmatically approuch and MVVM (Modal-View-ViewModel) architecture are being used for these key reasons:

• Separation of Concerns: MVVM cleanly separates the UI (View) from business logic and data (ViewModel), promoting code clarity and ease of maintenance.
• Testability: MVVM enables easy unit testing of ViewModel logic independently of the UI, leading to more robust and reliable code.
• Code Reusability: ViewModel classes in MVVM can be reused across different views, reducing duplication and promoting modular development.
• UI Responsiveness: MVVM's data binding mechanisms ensure that the UI updates automatically in response to changes in underlying data, enhancing user experience.
• Maintainability and Scalability: With its modular design, MVVM simplifies maintenance and enables the addition of new features without disrupting existing functionality.
• Support for Data Binding: MVVM aligns well with data binding frameworks, reducing boilerplate code and improving developer productivity.
• Enhanced Collaboration: MVVM's clear separation of concerns allows developers with different skill sets to work concurrently on different parts of the application.
• Adaptability to Platform Changes: MVVM provides a flexible architecture that can easily adapt to changes in platform requirements or UI frameworks, ensuring long-term viability.

Getting Started

Requirements

Before you begin, ensure you have the following:

• Xcode installed

Also, make sure that these dependencies are added in your project's target:

• Alamofire: Alamofire is an elegant HTTP networking library for Swift that simplifies network requests and handling responses.
• SDWebImage: SDWebImage is a widely-used library for asynchronously downloading and caching images in iOS and macOS applications, providing a seamless and efficient way to manage image loading.

Installation

1. Clone the repository:

git clone https://github.com/guraygul/CoinCo.git

2. Open the project in Xcode::

cd CoinCo
open CoinCo.xcodeproj

3. Add required dependencies using Swift Package Manager:

Alamofire
SDWebImage

4. Build and run the project.

Known Issues

• Learn more button has no padding for the bottom of the screen in IPhone SE due to Scroll View hierarchy
• Decentraland (MANA) image is bad due to the url of the API

Nice to have

• It would be better if we were fetching the data from a real-time API
• Localization for other languages can be added to be able to reach more user.
• More refactoring could be done for the Controllers.
