The Prototype pattern is a creational design pattern that specifies the kinds of objects to create using an instance of a prototype. Instead of instantiating new objects using a class directly (like with new), the pattern copies an existing object, thus cloning it to create new ones. This is useful when object creation …

The Factory Method is a creational design pattern that provides an interface for creating objects, but lets subclasses decide which class to instantiate. It promotes loose coupling by decoupling concrete classes from their creation logic. This example implements a VehicleFactory that defines a method createVehicle(). …

The Builder pattern is a creational design pattern that lets you construct complex objects step by step. The pattern allows separation of construction from representation, meaning the same construction process can create different representations. This is achieved by creating a separate builder class which encapsulates …

The Abstract Factory pattern provides an interface for creating families of related or dependent objects without specifying their concrete classes. It’s a creational pattern that promotes loose coupling and allows for easy switching between different “look and feels” or object sets.

The Swift code defines a …

The Peer-to-Peer (P2P) pattern enables direct communication and data exchange between individual nodes (peers) in a network, without relying on a central server. This implementation simulates a basic chat application where peers can send and receive messages directly. We use a simple Peer class to represent each …
