By the end, you won’t just “know SOLID” — you’ll be applying it instinctively, building systems that are stable under change and elegant under pressure
SOLID
SOLID isn’t just a list of principles — it’s the blueprint behind every scalable, maintainable, and testable software architecture. Yet most developers only grasp it at the surface level. This course breaks own each principle with real-world Swift examples, visual clarity, and use cases that transform how you design and structure your code. You won’t just memorize rules — you’ll walk away knowing why each principle exists, how to apply it confidently, and how to architect
systems that are built to grow

What You’ll Learn
Introduction to SOLID: Get an end-to-end understanding of what SOLID really is — and why it’s the foundation of clean architecture. Learn how these five principles eliminate code rot, reduce coupling, and future-proof your projects.
OCP: Open/Closed Principle: Stop rewriting code — start extending it. You’ll understand how to design flexible systems that are open for extension but closed for modification, using protocols, generics, and dependency inversion
ISP: Interface Segregation Principle: One size does not fit all. Learn how to split large protocols into smaller, role-specific ones — so your code stays focused, composable, and easy to mock or replace
SRP: Single Responsibility Principle: Unlock true modularity. Learn how to design types that do one thing well — and how this principle impacts reusability, testing, and long-term maintainability more than anything else
LSP: Liskov Substitution Principle: Master safe inheritance. Learn how to create subclasses that behave predictably, and how to avoid common violations that break polymorphism and crash your app in edge cases.
DI: Dependency Inversion Principle: Invert your thinking, elevate your architecture. Learn how to decouple high-level logic from low-level details using protocols, constructor injection, and service locators — making your code more testable, scalable, and clean.
