Advanced Swift: Generics and Protocols

Generics are a key feature in Swift, which, combined with protocols, let you build clean, reusable abstractions. Let's get started!

What happens when you abstract across a type? Let's take a look at a simple generic type to find out.

Let's see how you can use protocol constraints to inform the type system about the capabilities of a type.

You know how to make structs, enum and classes generic. Learn how to make protocols generic using associated types.

It's time for a challenge! Try to use your new knowledge of associated types to build a generic protocol.

In this video, learn how you can add constraints to associated types. Now even specify them recursively.

Find out how you can add additional API to a type depending on the capability of an associated type.

In this challenge, let's put your knowledge of conditional conformance into action by adding API to a type.

Swift has one of the most powerful generic systems available that balances performance with ease of use.
