Abstract: With more and more apps handling real-time dynamic data and UI there is a need for a robust way of handling multiple states. Redux has been successfully used for the same in the web world. I think its time the iOS world has a look at the huge capabilities this architecture provides. In this talk, we'll cover the basics of this architecture and how apps can benefit from the same

1. REDUX in iOS - Amruta Itagi
2. Why are we talking about it? We already have MVC, MVVM, VIPER, MVP, RIBLETS
3. What is REDUX
4. Redux Components State State • State is a struct which maps to states of applica3on Ac3on Ac3on • Ac3ons are just data that needs to passed
5. Redux Components Store Store • Store contains the state Reducer Reducer • Is a pure func4on which given a state and an ac4on returns a new State
6. Components in REDUX
7. Principles of Redux • Single Source of Truth • State is read only • Views cannot change the state directly
11. Redux Middlewares
12. Redux Middleware
13. Action Processing Patterns
14. Conclusion • Reducer is highly testable and maintainable • Business logic is not handled by View controllers • View is en8rely determinis8c. It is recalculated and redrawn solely based on the state • Hot reloading • Easy debugging • No more protocols, delegates or pipe a call from one view controller to another
