RxSwift vs ReactiveCocoa: which is better for legacy projects?

The question is about RxSwift .

Answer:
ReactiveCocoa was initially more prevalent in Objective-C/Swift iOS/macOS projects, but RxSwift is now more widely used, better supported, and offers easier onboarding thanks to greater documentation and resources. If maintaining older apps written with ReactiveCocoa, it may be necessary; otherwise, RxSwift is generally more future-proof and popular for ongoing legacy support.
