The view controller will have your regular ViewModels but you have some extension methods within the RxCocoa library. All I need for the successfully completed the project just the PSD design file of the project and a full description of your wishes. And this can be as async as you want. I mostly use RxSwift and MVVM architecture in projects. How do you convince people? The first part of my talk is going to be about MVVM, and we will get to some code.
