Protocols in Swift and interfaces in Kotlin are not just programming constructs; they’re powerful tools that empower you to write code that’s not only flexible but also follows best practices in software development. They’re more flexible than inheritance and provide a way to work with the same type for different use cases.
In this lesson, you’ll dive deeper into advanced features of protocols in Swift, such as composition and default implementations. These capabilities will let you work with different types in a unified manner and create code that’s easy to maintain. You’ll see how to pass around types as protocols, use associated types to gain the flexibility of working with generic data types and extend protocols for added functionality.
By the end of this lesson, you’ll have a comprehensive understanding of how to harness the full potential of protocols in Swift, allowing you to write clean, modular and highly adaptable code.
