Issue with UIScrollView not scrolling properly in iOS 17 with Auto Layout
I'm stuck on something that should probably be simple. I've searched everywhere and can't find a clear answer... I'm facing an issue with a `UIScrollView` in my iOS app that doesn't allow scrolling as expected, especially when using Auto Layout. I have a `UIView` inside the `UIScrollView`, and I'm setting constraints programmatically. Even though I set the content size, the scroll view just doesn't seem to scroll when the content exceeds the frame size. Here's a simplified version of the code I'm using: ```swift class MyViewController: UIViewController { let scrollView = UIScrollView() let contentView = UIView() override func viewDidLoad() { super.viewDidLoad() setupScrollView() } func setupScrollView() { view.addSubview(scrollView) scrollView.translatesAutoresizingMaskIntoConstraints = false scrollView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true scrollView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true scrollView.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true scrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true scrollView.addSubview(contentView) contentView.translatesAutoresizingMaskIntoConstraints = false contentView.topAnchor.constraint(equalTo: scrollView.topAnchor).isActive = true contentView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor).isActive = true contentView.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor).isActive = true contentView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor).isActive = true // Setting a height constraint to exceed the view’s height contentView.heightAnchor.constraint(equalToConstant: 1200).isActive = true } } ``` I’ve tried adjusting the content size manually, but it seems to conflict with Auto Layout calculations. The scroll view’s content size remains at the view's height, and I get the following warning in the console: ``` [LayoutConstraints] The view hierarchy is not constrained properly. The content view's height must be greater than the scroll view's height. ``` It's perplexing since I am setting the height constraint for the content view. Any suggestions for workaround or best practices on how to fix this issue? Also, I am using Xcode 15 and targeting iOS 17. I'm working with Swift in a Docker container on Debian. Thanks for taking the time to read this!
