In this lesson, you’ve scratched the surface of powerful Swift protocols, which enable you to model behavior that isn’t connected to inheritance. Protocols offer a flexible way to define blueprints for methods, properties and requirements, allowing your code to adapt and be more reusable.
Unlike traditional inheritance, both classes and structs can adopt multiple protocols as necessary. Swift has several standard library protocols such as Equatable and CustomStringConvertible, which you used in this lesson. Additionally, you can define your own to create reusable code that defines interfaces or functionality.
By embracing protocols, you unlock the potential for adaptable Swift code.
