Basics: Equality

Read Original

This article details Swift's protocol-oriented approach to equality via the Equatable protocol. It explains how to implement equality for custom types, how the compiler can auto-synthesize equality checks, and how conditional conformance enables equality for collections like Array when their elements are Equatable. It contrasts value and reference type behavior.
