The updates to asyncSequence
were not explicitly mentioned in the provided context. However, there were several updates related to concurrency and async functions in Swift, which might be relevant:
-
Memory Allocation for Async Functions:
- Async functions allocate memory differently compared to sync functions. Instead of using a large contiguous stack, async tasks hold onto one or more slabs of memory. When an async function needs memory, it asks the task for it, and the task tries to satisfy the request from the current slab (Explore Swift performance).
-
Concurrency and Data Race Safety:
- Swift 6 introduces complete data race protection, ensuring that concurrency is handled safely. This includes improvements to data race checking and the introduction of new low-level primitives like atomics and mutexes (What’s new in Swift).
-
Concurrency Features in Swift Testing:
- Swift testing now supports parallel testing by default, and async conditions can be handled using the same concurrency features as in production code. This includes using
await
to suspend tests, allowing other test code to keep the CPU busy while work is pending (Go further with Swift Testing).
- Swift testing now supports parallel testing by default, and async conditions can be handled using the same concurrency features as in production code. This includes using
