iOS/Android/React Native Mobile Developer Coding Task

Many thanks for investing the time in interviewing with us. For the next step we would like you to create a Pokemon App (iOS/Android/React Native app) to display an initial list of Pokemons with a further list showing a list of Pokemons evolved from the initial Pokemon. Please submit the code for the specific platform your were asked to in the interview. For React Native candidates, please note since we use a type system in all of our projects, we would prefer if you use Typescript/flow to finish the challenge.

Please follow the following guidelines while developing : -

• Pokemon is a imaginary animal from the Pokemon video game, generally Pokemons evolve into new species as time evolves.
• Please use the Poke API v2 to fetch an initial list of pokemons and its various properties (plea

Please find my solution below:

1. I propose to use an MVVM based application architecture.
2. for iOS I would recommend data binding (View to ViewModel) using RxSwift for a sample implementation by myself click here.
3. for Android I would propose Data Binding with my own helper library. Rest of the document would only focus on an iOS solution.
4. As for code organisation, we can use an use-case based folder grouping.
5. We should also separate our classes into Entities, Domain Services, Application Services, Repositories and Network layer.
6. the RESTClient should be a singleton, sample [implementation here](https://github.com/aprofromindia/Yahoo-Weather/blob/master/Yahoo%20Weather/RE
