generics with protocols

Generics in Swift are a powerful feature that allows you to write flexible and reusable code. They enable you to create functions and types that can work with any type, subject to certain constraints. In the context of protocols, generics can be used to define functions or types that operate on any type conforming to a specific protocol.

For example, in the session titled "Consume noncopyable types in Swift," it is explained how Swift's generics model can be used with noncopyable types. This session discusses how you can use noncopyable generics in Swift 6, which is built on Swift's existing generics model. The session also covers how conformance constraints describe generic types and how you can remove constraints like copyable to allow more flexibility with noncopyable types.

In another session, "A Swift Tour: Explore Swift’s features and design," the use of generics with protocols is demonstrated by extending the Collection protocol to add a method called uniqued. This method works with any collection type whose elements conform to the Hashable protocol, showcasing how generics and protocols can be combined to create powerful abstractions.
