The concept of asynchronous threads and concurrency is a significant topic discussed at Apple's WWDC, particularly in the context of Swift 6. Swift 6 introduces enhancements to manage concurrency more effectively, using features like async/await syntax and actors to handle asynchronous operations safely and efficiently.
For example, in the session "Migrate your app to Swift 6," it is explained how Swift concurrency helps in organizing code execution across different queues, ensuring that operations are performed on the correct threads, such as the main actor for UI updates and dedicated actors for background tasks. This approach helps prevent data races and ensures that changes in the code do not inadvertently affect the application's behavior.
Additionally, the session "A Swift Tour: Explore Swift’s features and design" covers the use of async/await syntax to manage task suspension and execution, allowing the CPU to be utilized efficiently by yielding control when waiting for asynchronous operations to complete.
For more detailed insights, you can refer to the following sessions:
- Migrate your app to Swift 6 (Adopting concurrency features)
- A Swift Tour: Explore Swift’s features and design (Concurrency)
These sessions provide a comprehensive overview of how Swift 6 handles concurrency, making it easier for developers to write safe and efficient asynchronous code.
Go further with Swift Testing
Learn how to write a sweet set of (test) suites using Swift Testing’s baked-in features. Discover how to take the building blocks further and use them to help expand tests to cover more scenarios, organize your tests across different suites, and optimize your tests to run in parallel.
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 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.
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.
Meet FinanceKit
Learn how FinanceKit lets your financial management apps seamlessly and securely share on-device data from Apple Cash, Apple Card, and more, with user consent and control. Find out how to request one-time and ongoing access to accounts, transactions, and balances — and how to build great experiences for iOS and iPadOS.
Meet the Translation API
Discover how you can translate text across different languages in your app using the new Translation framework. We’ll show you how to quickly display translations in the system UI, and how to translate larger batches of text for your app’s UI.
What’s new in Xcode 16
Discover the latest productivity and performance improvements in Xcode 16. Learn about enhancements to code completion, diagnostics, and Xcode Previews. Find out more about updates in builds and explore improvements in debugging and Instruments.
