Protocol-oriented programming is a programming paradigm that emphasizes the use of protocols to define a set of requirements for types. In Swift, a protocol is an abstract set of requirements that a type can conform to by providing implementations for all of the protocol's requirements. This approach allows for building abstractions that work equally well with both value and reference types, unlike traditional object-oriented programming which often relies on class hierarchies.
For example, in Swift, you can declare a protocol with certain requirements and then have a type conform to that protocol by implementing those requirements. This allows for more flexible and reusable code. Protocols can be used to abstract over different types, such as the collection types in the Swift standard library, which include arrays, dictionaries, and sets.
If you're interested in learning more about protocols and their use in Swift, you might want to check out the session titled "A Swift Tour: Explore Swift’s features and design" from WWDC 2024, particularly the section on protocols. You can find more details in the session's chapter on protocols.
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.
Explore the Swift on Server ecosystem
Swift is a great language for writing your server applications, and powers critical services across Apple’s cloud products. We’ll explore tooling, delve into the Swift server package ecosystem, and demonstrate how to interact with databases and add observability to applications.
