MVC, MVP, MVVM, VIPER Patterns 1. MVC (Model-View-Controller) 🔔Components: 🔦Model: Holds data and business logic. 🔦View: Responsible for the UI representation. It notifies the controller about user actions and receives updates from it. 🔦Controller: Acts as an intermediary between View and Model, updating the Model based on user input, and updating the View accordingly. 🎤Workflow: 📌User interacts with the View. 📌The View notifies the Controller. 📌The Controller updates the Model (if needed). 📌The Model processes data and updates itself. 📌The Model notifies the View to refresh. 📌The View updates the UI with new data. 2. MVP (Model-View-Presenter) 🔔Components: 🔦Model: Holds data. 🔦View: UI component that interacts with the user. 🔦Presenter: Acts as an intermediary but contains presentation logic. 🎤Workflow: 📌User interacts with View. 📌View notifies Presenter. 📌Presenter requests data from Model. 📌Model provides data to Presenter. 📌Presenter updates View with new data. 📌The View then updates its UI. 3. MVVM (Model-View-ViewModel) 🔔Components: 🔦Model: Data and business logic. 🔦View: UI. 🔦ViewModel: Acts as a data binder and state manager. 🎤Workflow: 📌View observes the ViewModel. 📌View binds data to ViewModel. 📌When data changes in ViewModel, it notifies View. 📌Similarly, View notifies ViewModel of user actions. 📌ViewModel updates Model as required. 📌When Model updates, ViewModel updates and notifies View. 4. MVVM-C (Model-View-ViewModel with Coordinator) 🔔Extends MVVM by adding a Coordinator: 🔦The Coordinator manages navigation/control flow outside the View/ViewModel. 🔦Contains logic to control the flow of screens or modules. 🎤Workflow: 📌View binds to ViewModel. 📌The Coordinator manages control and manages overall flow. 📌View and ViewModel communicate data binding and notifying, while Coordinator controls navigation flow. 5. VIPER (View-Interactor-Presenter-Entity-Router) 🔔Components: 🔦View: Displays information to the user. 🔦Interactor: Contains business logic and interacts with data sources. 🔦Presenter: Formats data for display and handles presentation logic. 🔦Entity: Data models. 🔦Router: Manages navigation and module wiring. 🎤Workflow: 📌View notifies Presenter with user actions. 📌Presenter instructs Interactor to fetch or manipulate data. 📌Interactor processes data and returns results to Presenter. 📌Presenter formats the data and updates View. 📌Router manages navigation (like moving to other screens), managed by Presenter.
