Hey, Thanks.

You can use following function of FAPanels but you need to update it little bit.

    func isTopVC(_ root: UIViewController?) -> Bool {
        
        if root is UINavigationController {
            let nav: UINavigationController = root as! UINavigationController
            return nav.viewControllers.count == 1
        }
        else if root is UITabBarController {
            let tab: UITabBarController = root as! UITabBarController
            return  isTopVC(tab.selectedViewController!)
        }
        return root != nil
    }

To get the topViewController just return the root in above function in last line.

        print("qq")
        if var topController = UIApplication.shared.keyWindow?.rootViewController {
            while let presentedViewController = topController.presentedViewController {

when you reach to FAPanelController try getting its centre view controller and check its type. I think you need that.

[isaacraja15]

are you saying need to pass centre view controller ?

  let storyboard = UIStoryboard(name: "Main", bundle: nil)
            let cv = storyboard.instantiateViewController(withIdentifier: "CenterVC1") as! CenterVC
           let isss = isTopVC(cv)
            print(isss)
