Well, there are a few things you need to do:

1) set up variables that can be manipulated by another class

2) in the other view controller that you want to control it, create an instance of the class you want to be manipulated

3) once you have that instance, you can modify it at will

4) present the view controller

Example:

 let tableViewController = yourTableViewController()
 tableViewController.yourBoolProperty = true

 //perform any showing action you want

the idea is manage the control of a viewController from another viewController – Miller Mosquera Oct 06 '16 at 14:31
I'm not 100% sure what you mean by "manage the control." Can you give an example in pseudo-code of what you want to do? – gigadude7 Oct 06 '16 at 14:56
