The question about the difference between ReactiveSwift and Combine is not directly addressed in the provided context from the WWDC sessions. However, I can provide some general information about these two frameworks:

  • ReactiveSwift is a framework for reactive programming in Swift, developed by the community. It provides a declarative Swift API for processing values over time, which can be used to build complex asynchronous and event-driven applications.

  • Combine is Apple's own framework for reactive programming, introduced at WWDC 2019. It is integrated into the Swift language and provides a unified declarative Swift API for processing values over time, similar to ReactiveSwift. Combine is tightly integrated with Apple's platforms and frameworks, such as SwiftUI, and is optimized for performance and ease of use within the Apple ecosystem.

Both frameworks offer similar concepts like publishers, subscribers, and operators to handle asynchronous events and data streams. However, Combine is more deeply integrated with Apple's platforms and benefits from being part of the system, which can lead to better performance and easier integration with other Apple technologies.
