The document contains code examples that demonstrate how to use RxSwift and Combine to create and subscribe to subjects, handle events and threads, and dispose of subscriptions. Specifically, it shows: 1. Creating PublishSubjects and PassthroughSubjects and subscribing to map and print events. 2. Creating BehaviorSubjects and CurrentValueSubjects, assigning initial values, and subscribing to print values. 3. Creating DisposeBags and Cancelables to clear subscriptions and resources. 4. Using operators like subscribeOn, observeOn, and receiveOn to control thread handling and scheduling.
