Architecture

Here you will see what YourReviews is built of.

Modules

YourReviews project consists of 3 modules:

• App
• Networking

Networking

This module is the basement of the YourReviews app and represents the network layer. It allows us to make requests using plain Codable data structures and handle the results the same manner.

App

Literally the main target. It consists of three screens: ReviewsFeedViewController, ReviewDetailsViewController and FiltersViewController, designed using MVVM architectual pattern. I believe it's the best option for building an iOS application which roadmap is not transparent.

Main task of any architecture is to control complexity, i.e. amount of effort should be adequate comparing to the requested changes. And any iOS application in a nutshell is just a set of screens hence the nature of this screens dictates the architecture. In our case, we have just three screens:

1. Feed
2. Details screen
3. Filters

Details and Filters screens are passive, meaning they don't request any data by itself, just wait until something will push data into it.

Feed screen, on the other hand is dynamic, meaning it pulls data it needs to display.

Most popular alternatives, like MVP and VIPER are designed to push data into view, MVVM — to let view pull data from its viewModel.

And that, I believe, makes MVVM best option in our case, because lists are more than common in iOS application and most certainly are going to come up once application will start to grow. And if we take a look at the way lists can be built it iOS application:

1. UIKit (Regular UITable/UICollectionView) - pull data model
2. UIKit (Modern UICollectionView) — push data model
3. SwiftUI - pull data model

We see that MVVM is perfect for 2 out of 3 options (1 and 3), and just fine for the option 2, while MVP and VIPER really work well only with option 2.

Versioning

This repo do not use any versioning system because I have no plans of maintaining the application in the future

Troubleshooting

For any questions please fell free to contact Dmitry Volosach.

Further steps

• Add more filters
• Upgrade to current version of the API
• Add more info on details screen
