swift uikit navigation

I'm confused about I'm implementing a custom navigation bar transition animation on an iPhone 15 using UIKit, but the animation behaves inconsistently during device orientation changes... When I push a new view controller, the navigation bar slides up as expected, but if I rotate the device while the transition is happening, the navigation bar appears to glitch and snap into position instead of smoothly transitioning. I've tried using `UIView.animate` for the animation and added observers for orientation changes, but it hasn't solved the issue. Here's a snippet of the code I'm using: ```swift class CustomNavigationController: UINavigationController { override func viewDidLoad() { super.viewDidLoad() NotificationCenter.default.addObserver(self, selector: #selector(orientationChanged), name: UIDevice.orientationDidChangeNotification, object: nil) } @objc func orientationChanged() { let duration = 0.3 UIView.animate(withDuration: duration) { self.navigationBar.frame.size.height = self.navigationBar.isHidden ? 0 : 44 self.navigationBar.setNeedsLayout() self.navigationBar.layoutIfNeeded() } } override func pushViewController(_ viewController: UIViewController, animated: Bool) { super.pushViewController(viewController, animated: animated) UIView.animate(withDuration: 0.5) { self.navigationBar.alpha = 1.0 } } } ``` I've also checked if the `navigationBar.isHidden` property is causing any issues, but it seems to be functioning as intended. The glitch appears only when the device is rotated mid-animation, but otherwise, the animation is smooth. Has anyone encountered a similar issue with custom navigation transitions, or does anyone have suggestions on how to handle this case more gracefully? Any insights would be greatly appreciated! Any help would be greatly appreciated! I recently upgraded to Swift latest. Has anyone dealt with something similar? Thanks for taking the time to read this! This is happening in both development and production on Ubuntu 20.04.
