Task in Swift Concurrency
In the session titled "A Swift Tour: Explore Swift’s features and design," the concept of a task in Swift concurrency is introduced. A task represents an independent concurrent execution context. Tasks are lightweight, allowing you to create many of them. You can wait for a task to complete to get its result or cancel it if its work becomes unnecessary. Tasks can execute concurrently, making them ideal for handling HTTP requests, as mentioned in the session. As a task runs, it may perform asynchronous operations like reading from the disk or messaging another service. While a task is waiting for an asynchronous operation to complete, it suspends to yield the CPU to other tasks.
For more details, you can refer to the Concurrency section of the session "A Swift Tour: Explore Swift’s features and design."
Sessions Mentioned
- A Swift Tour: Explore Swift’s features and design
- Demystify explicitly built modules
- Discover Swift enhancements in the Vision framework
- Meet the Translation API
- Get started with Writing Tools
- Migrate your app to Swift 6
Get started with Writing Tools
Learn how Writing Tools help users proofread, rewrite, and transform text in your app. Get the details on how Writing Tools interact with your app so users can refine what they have written in any text view. Understand how text is retrieved and processed, and how to support Writing Tools in custom text views.
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.
