Stopping animation of SWRevealViewController on selection

I am trying to disable SWRevealViewController animation on row selection, it is a sliding menu library for use with swift or objective-c, what I say, when I select a row from the menu, it expands like 40 px, on the right, then it closes and goes away, I want edit it, so when I click on the line, it closes without expanding to the right.

I hope I have explained well and this is the library I am working with: https://github.com/John-Lluch/SWRevealViewController
