Change title of navigation controller from second view controller?

I have a view controller which has embedded a navigation controller.

From this view controller I am being able to change the title of the navigation bar with navigationItem.title = "title".

Furthermore I have another tableview controller and I want to update the tile of the navigation controller also from here, this tableview controller acts as a Slide Out Menu for the first view controller.

Navigation controller and tableview controller are not connected directly but I use a library called SWRevealViewController to create and connect the slide out menu with first view controller.

I have tried these codes:ViewController().navigationItem.title = "secondTitle"

I have also tried to put the process of changing the title in first controller in function and create an instance like :ViewController().updateNavTitle(), also tried to crete a segues but without any result.

Create a String variable in your first class and access this property in your Slide Out controller and and update it. Now in your first controller's in viewWillAppear method update the title like below.

override func viewWillAppear(animated: Bool) {

      super.viewWillAppear(animated)
      if self.updatedTitle != nil {
      self.navigationItem.title = self.updatedTitle//Create this String variable.
      }
}
