ReactiveCocoa version issue on pod install
ReactiveCocoa version issue on pod install

I tried to set up a project with Moya + ReactiveCocoa and got this error when following the README and typing "pod install":
```
Analyzing dependencies
[!] Unable to satisfy the following requirements:

- `ReactiveCocoa (= 3.0.0-beta.6)` required by `Podfile````
Then I changed it to '3.0-beta.6' because I saw it in your .podspec and it worked.
