Protocol-oriented programming is a programming paradigm that emphasizes the use of protocols to define interfaces and abstractions in Swift. A protocol is an abstract set of requirements for a type, and a type can conform to a protocol by implementing all of its requirements. This approach allows for building abstractions that work equally well with both value and reference types, providing a more flexible alternative to traditional class hierarchies.
In Swift, protocols can be used to define common functionality that different types can share, without being limited to a specific class hierarchy. This is particularly useful for creating generic and reusable code. Protocols can be extended to add methods, properties, and protocol conformances to any type, regardless of where that type is defined.

Consume noncopyable types in Swift
Get started with noncopyable types in Swift. Discover what copying means in Swift, when you might want to use a noncopyable type, and how value ownership lets you state your intentions clearly.
Explore Swift performance
Discover how Swift balances abstraction and performance. Learn what elements of performance to consider and how the Swift optimizer affects them. Explore the different features of Swift and how they’re implemented to further understand the tradeoffs available that can impact performance.
A Swift Tour: Explore Swift’s features and design
Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.
