What design patterns are traditionally used in mobile development?

MVC (Model–View–Controller): Divides the application into three interconnected parts: Model (data and business logic), View (UI), and Controller (the connecting link).

MVP (Model–View–Presenter): An improved version of MVC, where the Presenter takes responsibility for the presentation logic, making the View more passive.

MVVM (Model–View–ViewModel): Uses a ViewModel that contains presentation logic and data, which the View binds to. Simplifies testing and separation of concerns.

Observer (Observer): Allows objects (observers) to subscribe to changes in another object (subject) and receive notifications when they occur. Often used for handling UI events or data changes.

Singleton (Singleton): Ensures that a class has only one instance and provides a global point of access to it. Used for managers, services.

Factory (Factory): Provides an interface for creating objects of a family of classes but allows subclasses to choose the type of objects to create. Used for encapsulating object creation logic.

Dependency Injection (Dependency Injection): Allows objects to receive their dependencies from outside rather than creating them themselves. Improves testability and flexibility. Examples: Dagger, Koin.

Repository (Repository): Abstracts access to data from various sources (database, network, cache). Provides a clean API for working with data.

Strategy (Strategy): Defines a family of algorithms, encapsulates each one, and makes them interchangeable. Allows selecting an algorithm at runtime.
