It is very easy to work with CocoaPods; you can install RxSwift like any other library by making use of a pod file. A simple example of a pod file is as follows:
use_frameworks!target 'YOUR_TARGET_NAME' dopod 'RxSwift'pod 'RxCocoa'end
RxTests and RxBlocking make the most sense in the context of unit/integration tests:
target 'YOUR_TESTING_TARGET' do pod 'RxBlocking' pod 'RxTest'end
It's totally up to you to include any number of libraries with the RxSwift library, depending on your requirements. Of course, you can choose just one, a combination of RxSwift and RxCocoa, or all of them.
