A cat, in the context of the WWDC sessions, is used as an example in programming with Swift. Specifically, in the session titled "A Swift Tour: Explore Swift’s features and design," a cat class is used to illustrate concepts of object-oriented programming, such as inheritance and memory management. The cat class inherits from a superclass called PET, and methods on the superclass can be overridden by methods on the subclass. This example helps explain how Swift manages memory automatically for reference types using a feature called automatic reference counting.
For more details, you can refer to the session A Swift Tour: Explore Swift’s features and design at the timestamp 12:37.
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.
