Hi Brian, I'm assuming I should in that case completely disregard the BaseSlidingController and simply run all the code from there into my MainNavigationController? Any tips on how to do this? :)

But with your solution I would be calling closeMenu() from my navigationcontroller, although it lives within BaseSlidingController. Excuse my ignorance.

Ok so in other words: I want to build this slidermenu into my current app which holds a navigation controller that initially holds a logincontroller as its main viewcontroller. Once the user logs in, the mainnavigation controller's main controller will be changed to the BaseSlidingController as such: let rootViewController = UIApplication.shared.keyWindow?.rootViewController guard let mainNavigationController = rootViewController as? MainNavigationController else { return } mainNavigationController.viewControllers = [BaseSlidingController()] self.navigationController?.popToRootViewController(animated: true) .. Instead of the redview you are using, in my case is a view that holds a map and additional buttons that use the pop function from the main navigation controller to other viewcontrollers. I'm trying to combine profile related viewcontrollers from within the slidingmenu with the current mapview including some buttons. But like I said, I get stuck at the point where I need to access the BaseSlidingController's closeMenu() function because the MainNavigationController is the root. With your initial solution I get the error: "Value of type 'MainNavigationController' has no member 'closeMenu'" Hence I wondered as to why I would refer to the MainNavigationController to access the openMenu() function as it doesn't have this function because it lives in the BaseSlidingController. Is there a way to combine this slidermenu with the current structure I am using? The slidermenu works fine up until the point I need to access the closeMenu() function to allow for the menu item selection in the slidermenu. Or is this slidermenu's sole purpose to act as a main navigation and thus will not combine with a navigationcontroller?

I tried the exact same thing, receiving the exact same error.

Thanks

Nevermind, I got it. For anyone that may need it: let flowLayout = UICollectionViewLayout() rightViewController = CustomCollectionViewController(collectionViewLayout: flowLayout)

Ok nevermind, actually the fix was in your next video, by moving closeMenu() up before the switch statement. But I do not understand why would that fix the issue? Is it because of the layoutIfNeeded? which the view redraws itself?

If anyone is interested I solved this with NotificationCenter In BaseViewController viewDidLoad I have NotificationCenter.default.addObserver(self, selector: #selector(openMenu), name: Notification.Name(rawValue: "openMenu"), object: nil) In my main vc navbutton I have NotificationCenter.default.post(name: Notification.Name(rawValue: "openMenu"), object: nil)

thank you I needed that

Can anyone help me ? I can't solve this problem

But my HomeController is a CollectionViewController and it has a lot of headaches about layout issues and also I am using storyboard. I just want call a func from another controller its looking so basic but I can't even do this. Sorry I am new about swift.

Correction, the indexPath goes through but the closeMenu() crashes for some reason

I see what u mean.. not sure how to do that either

I did it!!! YEEEEESSS lmao let tabBarController = UIApplication.shared.keyWindow?.rootViewController as? BaseTapBarController let slidingController = tabBarController?.viewControllers?[0] as? BaseSlidingController slidingController?.didSelectMenuItem(indexPath: indexPath) it only took me a few hours to figure it out lol... don't know if this is still the best practice...
