Microservices - Swift

The Microservices pattern structures an application as a collection of loosely coupled, independently deployable services, modeled around a business domain. Each service owns its data and communicates via lightweight mechanisms, often a RESTful API. This example demonstrates a simplified implementation with two …

N-tier - Swift

The N-tier pattern organizes an application into distinct layers, each with a specific responsibility. This promotes separation of concerns, making the application more maintainable, testable, and scalable. A typical N-tier architecture includes a presentation tier (UI), a business logic tier, and a data access tier. …

Client-Server - Swift

The Client-Server pattern decouples a service provider (Server) from its consumers (Clients). The Server provides resources or functionalities, and Clients request and utilize them. This enables scalability, reusability, and independent development of client and server. Here, we simulate a simple temperature server …

Self-contained Systems - Swift

The Self-Contained Systems pattern aims to reduce coupling by ensuring each system (or module) has everything it needs to operate – its data, dependencies, and logic – without relying excessively on external components. This fosters independence, testability, and reusability.

This Swift implementation models a …

Monolith - Swift

The Monolith pattern represents a traditional, unified application structure where all components are tightly coupled and deployed as a single unit. Our Swift example will simulate this by having a single App class managing all functionality – user management, data handling, and a simple display mechanism. While modern …

Microkernel - Swift

The Microkernel pattern structures an application with a core system providing minimal functionality and extending features via plug-ins. This promotes modularity and flexibility, allowing functionalities to be added, removed, or updated without affecting the core.

This Swift example models a simple text processing …

Clean Architecture - Swift

Clean Architecture aims to create systems independent of frameworks, databases, UI, and external agencies. It achieves this through layered organization: Entities (core business logic), Use Cases (application-specific business rules), Interface Adapters (presenters, controllers, gateways), and Frameworks & Drivers …

Onion Architecture - Swift

The Onion Architecture organizes code into concentric layers, with core business logic at the center and infrastructure concerns at the outer layers. Dependencies point inwards – outer layers depend on inner layers, but inner layers have no knowledge of the outer ones. This promotes testability, maintainability, and …

Hexagonal Architecture - Swift

The Hexagonal Architecture (Ports and Adapters) aims to create loosely coupled software, isolating the core business logic from external concerns like UI, databases, and external services. This is achieved through defining ports (interfaces defining interactions with the core) and adapters (implementations of those …

Layered Architecture - Swift

The Layered Architecture pattern organizes an application into distinct layers, each with a specific responsibility. This promotes separation of concerns, making the code more maintainable, testable, and adaptable to change. Common layers include Presentation (UI), Business Logic (Use Cases), Data Access …
