Example of an iOS Feature Module implemented with a Redux-like Pattern

Product and Technical Requirements

• Load a list of countries from the API.
• Load information from another API after the total number of countries is known.
• Support paging: Load the next page when reaching the bottom of the list.
• Support reload functionality.
• Display countries in a list with an information header.
• Utilize the Combine and SwiftUI frameworks.

Types

• Store: Holds the State of the feature, calls the Reducer with dispatched Actions, and updates the State.
• State: Contains information needed to render the feature's UI and other helper data.
• Action: Enumeration of all possible changes to the State.
• Reducer: An object that, given an Action, mutates the State and optionally emits an Action publisher.
• ActionCreator: Creates an Action publisher from long-lasting work, such as a network call.
• Adapter: Converts "raw" types, such as API responses, into models ready to be rendered by the UI.
