   3. Initialize pods in the new project (pod init in terminal)
   4. Edit Podfile, add RxSwift, RxCocoa
   5. Install pods (pod install in terminal)
   6. Open RxSwiftProject.xcworkspace created by CocoaPods
   7. Build and run project using default scheme
   8. Add a new playground, Xcode menu > File > New > Playground…
   9. Select Add to: RxSwiftProject , to add it to the RxSwift workspace

example code here

No longer works in Xcode 9.1

$ pod playgrounds RxSwift,RxCocoa

gives

Errno::ENOENT - No such file or directory @ dir_initialize - /Applications/Xcode.app/Contents/Developer/Library/Xcode/Templates/File Templates/Source/Playground with Platform Choice.xctemplate

1. You should clone the RxSwift repository on your computer
2. Open Rx.xcworkspace
3. Build the RxSwift-macOS scheme
4. Open Rx.playground in the Rx.xcworkspace tree view and add a new page
5. import RxSwift in the new page.
6. Choose View > Debug Area > Show Debug Area

As @sas has hinted at, you can use Arena.
