App Structure with Redux
• use ReSwift or your own implementation
• don’t keep everything in the AppState
15 Feb 2017 3. Conclusions
• unidirectional flow (readable)
• functional & reactive (testable)
• good separation of concern (maintainable)
• compatible with VIPER
15 Feb 2017 3. Conclusions
• ReSwift documentations isn’t that good
• App State is a God Object
When Redux works• App with lots of global state
• Apps with history of state (such as undo and redo actions)
• Apps with a number of async events.
• Apps where you need to save navigation state between sessions.
