Equatable conformance in Swift explained with code examples
Conforming to the Equatable protocol allows objects to be compared with one another. You can either rely on Swift's default implementation or provide custom comparison logic. In this article, Antoine van der Lee explores the implementation of Equatable conformance for custom types and how to make objects from third-party libraries conform to the protocol.
