Method Dispatch in Swift
In the session titled "Explore Swift performance" from WWDC 2024, method dispatch is discussed in the context of static and dynamic dispatch. Here's a summary of the key points:
-
Static Dispatch: This occurs when the compiler knows at compile time exactly which function is being called. Static dispatch is more efficient because it allows for optimizations like inlining and generic specialization. This type of dispatch is used when the function is declared in a protocol extension.
-
Dynamic Dispatch: This is used when the exact function to be called is determined at runtime. It enables polymorphism and is used when a function is a protocol requirement, meaning it is declared in the main body of the protocol.
The distinction between static and dynamic dispatch is crucial for both semantic understanding and performance optimization in Swift.

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.
Discover Swift enhancements in the Vision framework
The Vision Framework API has been redesigned to leverage modern Swift features like concurrency, making it easier and faster to integrate a wide array of Vision algorithms into your app. We’ll tour the updated API and share sample code, along with best practices, to help you get the benefits of this framework with less coding effort. We’ll also demonstrate two new features: image aesthetics and holistic body pose.
Migrate your app to Swift 6
Experience Swift 6 migration in action as we update an existing sample app. Learn how to migrate incrementally, module by module, and how the compiler helps you identify code that’s at risk of data races. Discover different techniques for ensuring clear isolation boundaries and eliminating concurrent access to shared mutable state.
