Crash with message "Invalid parameter not satisfying: [views count] == 3" + FIX

[salvasp]

If swipe quickly between pages I sometime get the error inconsistent exception "Invalid parameter not satisfying: [views count] == 3"

seems can be fixed replacing inside "open class PageboyViewController: UIViewController"

pageViewController.setViewControllers(viewControllers,
                                                  direction: direction.pageViewControllerNavDirection,
                                                  animated: false,
                                                  completion:
                { (finished) in
                    self.isUpdatingViewControllers = false
                    
                    if !animated {
                        completion?(finished)
                    }
            })    

with

     DispatchQueue.main.async {
            pageViewController.setViewControllers(viewControllers,
                                                  direction: direction.pageViewControllerNavDirection,
                                                  animated: false,
                                                  completion:
                { (finished) in
                    self.isUpdatingViewControllers = false
                    
                    if !animated {
                        completion?(finished)
                    }
            })            
        }

@salvasp thanks for all the detail, just released a new version with this fix in. Let me know how you get on with it! 😄 v2.3.4

[salvasp]

yes seems to work.
Have you panned something like extending
func viewController(for pageboyViewController: PageboyViewController, at index: PageboyViewController.PageIndex) -> UIViewController?
with somentig like
func viewController(for pageboyViewController: PageboyViewController, at index: PageboyViewController.PageIndex, reusingViewController: UIViewController?) -> UIViewController?
to reuse the cached view controllers?
I commented the issue #124 with some idea but for now I'm using in one case the variable [UIViewController?] (in the comments after the NSCache row) because i have just 6 view controllers.
in another case 50+ view controllers I create a view controller (let controller = storyboard.instatiate....; return controller) each time "viewController for" is called

@salvasp I'll take a look! Reuse / improved insertion is high on the list for Pageboy 3, so hopefully will get to start working on it shortly 😄
