implementing UIScrollView not respecting contentInset for safe area insets in iOS 17

ios uiscrollview safe-area Swift

I'm building a feature where I'm stuck on something that should probably be simple... I've been banging my head against this for hours. I am working with a question where my `UIScrollView` is not properly respecting the `contentInset` for the safe area insets on iOS 17. I have set up a scroll view that contains a `UIView`, but when I adjust the `contentInset` to account for the safe area, it does not seem to take effect as expected. Here's an example of my implementation: ```swift class MyViewController: UIViewController { @IBOutlet weak var scrollView: UIScrollView! override func viewDidLoad() { super.viewDidLoad() setupScrollView() } private func setupScrollView() { // Adjust contentInset for the safe area insets let safeAreaInsets = view.safeAreaInsets scrollView.contentInset = UIEdgeInsets(top: safeAreaInsets.top, left: 0, bottom: safeAreaInsets.bottom, right: 0) scrollView.scrollIndicatorInsets = scrollView.contentInset } } ``` However, I notice that even after setting the `contentInset`, the scroll view content is still partially obscured by the navigation bar at the top. I also tried updating the insets in `viewWillLayoutSubviews` to ensure it accounts for any layout changes: ```swift override func viewWillLayoutSubviews() { super.viewWillLayoutSubviews() let safeAreaInsets = view.safeAreaInsets scrollView.contentInset = UIEdgeInsets(top: safeAreaInsets.top, left: 0, bottom: safeAreaInsets.bottom, right: 0) scrollView.scrollIndicatorInsets = scrollView.contentInset } ``` Even with these adjustments, the scenario continues and the content still appears cut off. I’ve confirmed that my scroll view's autoresizing masks are set correctly, and I double-checked the constraints as well. Is there a specific configuration I might be missing or perhaps a known scenario with `UIScrollView` handling safe area insets on iOS 17? Any advice would be appreciated! Am I missing something obvious? Has anyone else encountered this? This is happening in both development and production on macOS.
