Created issue in RxSwift

Today, I got up early morning about at seven.
Usually I get up at ten to eleven, So this is very early.
After got up, I wrote codes in my products with friends.
And I found chance for committing RxSwift which is open source software.

This is a very big chance for me and iOS Engineer.
So, immediately I created issue with GitHub.
This is my first issue in RxSwift.
https://github.com/ReactiveX/RxSwift/issues/1761

This will make me very fun for developing.
Thanks!
