I have an issue of moving from a ViewController back to a root tab bar controller. Here's my storyboard, I have attached an image of my issue. I have tried the following: let homeTBC = controllers![3] as! UITabBarController 				let homeVC = homeTBC.viewControllers?[0] as! HomeViewController 				self.present(homeVC, animated: true, completion: nil) I'm getting this error message: terminating with uncaught exception of type NSException Please help really running out of options here.
