Answer 1

To get the needed behavior, one must the following:

1. Set the semantic property of your collection view to Force Left to Right
2. In the override func viewControllers(for pagerTabStripController: PagerTabStripViewController) -> [UIViewController] method reverse the view controllers array before returning it

3. In ViewWillAppear go to the last element of the array but make sure to dispatch to the main queue

   DispatchQueue.main.async {
       if(self.itemsList.value.count > 0){
           self.moveToViewController(at: self.itemsList.value.count-1, animated: false)
       }
   
   }
