The comparison between asyncSequence and Combine was not directly covered in the provided context from the WWDC sessions. However, I can provide some general insights based on the information about Swift concurrency and testing features discussed in the sessions.
Swift's concurrency model, which includes async and await, is designed to be a more straightforward and integrated approach to handling asynchronous operations compared to Combine. asyncSequence is part of this model, allowing for asynchronous iteration over a sequence of values. It provides a more native and language-integrated way to handle asynchronous streams of data.
On the other hand, Combine is a framework introduced by Apple to handle asynchronous events through a reactive programming model. It uses publishers and subscribers to manage data flow and transformations.
The key differences are:
-
Integration:
asyncSequenceis part of Swift's language-level concurrency features, making it more integrated with Swift's syntax and type system. Combine is a separate framework that requires importing and using its specific types and operators. -
Complexity:
asyncSequencetends to be simpler and more straightforward for developers familiar with Swift's concurrency model. Combine offers more powerful and flexible operators for complex data transformations but can be more complex to use. -
Use Cases:
asyncSequenceis ideal for straightforward asynchronous data streams, while Combine is better suited for complex data processing pipelines and reactive programming patterns.

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.
What’s new in Swift
Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
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.
