It providers a scheduler to run code in the main thread of Android. Someone may propose to use Observable in the protocol instead of BehaviorRelay, i.e. RxCocoa: Provides Cocoa-specific capabilities for general iOS/macOS/watchOS & tvOS app development, such as Shared Sequences, Traits, and much more. In the first part we set up RxSwift from Cocoa pods and checked how to use BehaviorRelay, Observable and PublishSubject.This time we will create a view that we can use to create and update friends to the server.
