Not that long ago, I wrote how to pair RxSwift with MVVM architecture in an iOS project. Even if I refactored my code to be reactive, I omitted to mention the unit tests. Today I’ll show step by step how to use RxTest to unit test your code.
For years now, the whole iOS community has written content about the best way to improve or replace the Apple MVC we all started with, myself included. MVC, MVVM, MVP, VIPER? Regardless the type of snake you have chosen, it’s time to reflect on that journey.
After introducing how to implement Coordinator pattern with an MVVM structure, it feels natural for me to go further and cover some of the blank spots of Coordinator and how to fix along the way.
After some times creating different iOS apps following an MVVM pattern, I’m often not sure how to implement the navigation. If the View handles the rendering and user’s interactions and the ViewModel the service or business logic, where does the navigation sit? That’s where Coordinator pattern takes place.
Apple introduced in iOS8 trait variations that let developers create more adaptive design for their mobile apps, reducing code complexity and avoiding duplicated code between devices. But how to take advantage of variations for UICollectionView?
This post will cover how to setup variations via Interface Builder as well but also programatically, using AutoLayout and UITraitVariation with a UICollectionView to create a unique adaptive design.
For last couple weeks, I’ve worked a lot about how to integrate RxSwift into an iOS project but I wasn’t fully satisfied with the view model. After reading many documentation and trying on my side, I’ve finally found a structure I’m happy with.
