structured concurrency

Structured concurrency in Swift is a key topic discussed in several sessions at WWDC 2024. Here are some relevant points and sessions that cover this topic:

1. Migrate your app to Swift 6:

   • This session discusses the advantages of concurrency, particularly data race safety, which allows developers to leverage concurrency without fear of introducing new data races. The session also covers how to update an app to Swift 6 to avoid concurrency bugs.
   • The session explains how adopting Swift concurrency can transform an ad hoc concurrency architecture into a more organized structure using actors and async/await features.
   • It also provides practical steps for enabling strict concurrency checking and handling warnings and errors related to concurrency issues.

2. What’s new in Swift:

   • This session highlights the improvements in Swift 6, including data race safety by default, which turns data race issues into compile-time errors.
   • It introduces new low-level synchronization primitives like atomics and mutexes, which are designed for efficient, lock-free implementations and safe concurrent access.

3. A Swift Tour: Explore Swift’s features and design:

   • This session covers the basics of writing concurrent code in Swift, including tasks, async/await, and actors. It emphasizes the importance of data race protection in ensuring that concurrent code is handled correctly.

For a deeper dive into structured concurrency, you can check out the following chapters and timestamps:

• Migrate your app to Swift 6 (Adopting concurrency features)
• What’s new in Swift (Swift 6 language mode and data-race safety)
• A Swift Tour: Explore Swift’s features and design (Concurrency)

These sessions provide comprehensive insights into how Swift 6 enhances concurrency management and ensures data race safety, making it easier for developers to write robust and efficient concurrent code.
