MVVM. MVP. VIPER. Clean. In modern iOS applications, we often use a specific architecture or design pattern to break our software down into individual components that are easy to read and understand and that are easy to test.

Protocol Oriented Tips for MVVM in Swift
Hi folks. Lately MVVM has become some sort of standard as an architecture for iOS apps. It offers a good separation of concerns, a good way to format data and great view binding mechanisms with frameworks such as RxSwift. In this post I will give few tips I use to ease the implementation of this pattern. Views made easy with ReusableWith MVVM, separation between Views and the rest of your architec
