This is an open project to show a way to implement CLEAN architecture on our iOS apps. There's not only one way to implement it so this is my approach. For that reason, I was inspired on VIPER, MVP and MVVM architectures. The most important is to take the advantages of each architecture and create your own view. In this project I decided to have a big dependency of RxSwift, it's an example of a common situation when you are the owner of the project and you need to decide which dependencies you have and which you want to avoid. But one thing for sure, working with tests is the most important, try to have tests for each layer and working with approach like TDD or ATTD. Because the tests give us a good perspective to build our architecture, meet the CLEAN principles and avoid lot of bugs in the future.

This project use Moya (Rx Wrapper works with Alamofire as a Network Service client to obtain a list of users from Marvel API. And render this data on a Master-Detail app, with a list of comics and a detail for each one. Also have the posibility to filter comics by type. Using a beautifull filter approach with UIStackView.

This is the best approach of CLEAN architecture for iOS. We have some layers to share the logic around, each layer has his own responsibility. You can see a visual scheme to understand better how it works:

• View - Customize UI
• Presenter - Presentation Logic
• Router - Navigation layer
• Interface - Business logic
• Repository - Bridge between data and business logic
• Client - Data layer, we can have DataBases, Network connections, Frameworks store, Memory, etc.

For each project the developers should decide what approach of test pyramid they need or they want to have. My favorite is an approach from the practical test pyramid of Martin Fowler:

At the moment this project only have the bottom layer, Unit Tests. But at one point I will add more tests for the other layers to show how can do it for iOS.

I use a third party service to obtain Marvel Comics. You can find out more about this service on:

Marvel API

git clone 

cd /workdir

pod install

open Marvel.xcworkspace

Remember to fill the env.json file with your API_Key and API_secret obtained form Marvel API service.

Please make sure to update tests as appropriate.
