Problems with UIScrollView Content Inset Adjustments on iOS 16

I'm encountering an issue with a `UIScrollView` where the content inset is not behaving as expected when the safe area insets change. I'm using iOS 16 and have enabled `automaticallyAdjustsScrollViewInsets` on my `UIViewController`, but the content inset seems to be incorrect when the keyboard appears or when I rotate the device. Here's a simplified version of my code: ```swift class MyViewController: UIViewController { @IBOutlet weak var scrollView: UIScrollView! override func viewDidLoad() { super.viewDidLoad() scrollView.contentInsetAdjustmentBehavior = .automatic } override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(_:)), name: UIResponder.keyboardWillShowNotification, object: nil) NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(_:)), name: UIResponder.keyboardWillHideNotification, object: nil) } @objc func keyboardWillShow(_ notification: Notification) { guard let userInfo = notification.userInfo, let duration = userInfo[UIResponder.keyboardAnimationDurationUserInfoKey] as? Double else { return } UIView.animate(withDuration: duration) { self.scrollView.contentInset.bottom = 300 // Adjusting manually self.scrollView.scrollIndicatorInsets.bottom = 300 } } @objc func keyboardWillHide(_ notification: Notification) { guard let userInfo = notification.userInfo, let duration = userInfo[UIResponder.keyboardAnimationDurationUserInfoKey] as? Double else { return } UIView.animate(withDuration: duration) { self.scrollView.contentInset.bottom = 0 self.scrollView.scrollIndicatorInsets.bottom = 0 } } } ``` The `scrollView` is supposed to adjust its content insets automatically, but when the keyboard shows up, the insets don't seem to reflect accurately, causing the scroll indicators to overlap with the input fields. I’ve tried adjusting the `contentInset` and `scrollIndicatorInsets` in response to keyboard notifications, but it doesn't seem to fix the overall scroll behavior; in fact, the extra inset seems to be contributing to a jumpy user experience as I show/hide the keyboard. I also checked my constraints and ensured there’s no conflicting layout that might affect the scroll view. Has anyone else faced this issue? Any insights into how to properly manage content insets for `UIScrollView` in this context would be greatly appreciated!
