今日こそ理解するHot / Cold @社内RxSwift勉強会
This document discusses hot and cold observables in RxSwift. It explains that subjects produce hot observables while operators produce cold observables. It provides examples of how cold observables resubscribe to source sequences while hot observables multicast their values to multiple observers. The document answers questions about the differences between hot and cold observable behavior.
