About this course

Transitioning from traditional object-oriented programming to a protocol-oriented mindset is key to unlocking the full potential of Swift. By focusing on protocols and value types, you can design highly modular, testable, and robust iOS applications. This course guides you through the core principles of Protocol-Oriented Programming (POP) in Swift. You will transition from rigid class hierarchies to flexible, composition-based designs, learning how to leverage protocols to write cleaner and more maintainable code. What you'll learn: - Understand the foundational differences between classes and structs, and when to use value types versus reference types. - Declare and conform to custom protocols with various properties, methods, and initializers. - Implement the delegate pattern and other common design patterns using protocols. - Extend protocols to provide default implementations, reducing repetitive boilerplate code. - Apply advanced protocol concepts such as composition, inheritance, and associated types. - Explore modern Swift features including existential types and opaque types to write flexible APIs. You will start by mastering foundational concepts like value semantics and basic protocol syntax before moving on to real-world architectural patterns and advanced composition techniques. The written explanations and practical code examples will help you confidently apply these paradigms to your own projects. This course is designed for beginner to intermediate iOS developers who have a basic understanding of Swift syntax and want to elevate their software design skills. Start reading today to transform the way you architect your Swift applications.

Decent introduction. The structure was logical, but I wish there had been more hands-on practice beyond the basic examples.

Tbh, I expected more practical application. It felt a bit too theoretical for my needs, though the core concepts were explained okay.
