Hello I set a few constraints on a UIView in the storyboard. The height constraint is set to 300 and has a size class variation set on 350 (see screenshot). In my code, I modify the constraint and set its constant to 100. When I call that code, I see the view changing correctly its height to 100. But If I go to homescreen ( app in background) and come back to the app, the height of the view is set back to the old value (300). This problem only appears when the constraint has a size variation. When I remove the variation on the height, the behaviour is ok, the height stays at 100 when I go to homeview and switch back to the app. Is that a bug of AutoLayout ? Is there a workaround ? (tested with iOS16, on iPhone Xr and iPhone 14 Pro, xcode 14) class ViewController: UIViewController {     @IBOutlet weak var heightConstraint: NSLayoutConstraint!     override func viewDidLoad() {         super.viewDidLoad()     }     @IBAction func buttonPushed(_ sender: Any) {         heightConstraint.constant = 100; // works ok until app goes background     } }
