One of the variants of the Subject is the BehaviorSubject. Successfully merging a pull request may close this issue. Filters the elements of an observable sequence based on a predicate by incorporating the element's index. This lesson will teach you how and when to use a BehaviorSubject to mitigate that problem. We've tried to add a lot of example usages to RxExample app, so if there is some question about some of examples there, I would be happy to answer them. Variable exists because people usually have a hard time finding BehaviorSubject and Swift has additional complexity of memory management.
