It seems to be a UICollectionViewCompositionalLayout. With list configuration for items and section for image and info.

I have exactly the same issue without any code changes. Even compiled with Xcode 16.4

This implementation only works with UIBarButtonItem in navigation bar. Here is sample code for UIButton: button.menu = .init(children: [ UIAction(title: "title", handler: { _ in }) ]) button.showsMenuAsPrimaryAction = true

We figured it out. The problem was in outlet named searchBar.

final class TabBarController: UITabBarController { override func viewDidLoad() { super.viewDidLoad() if #available(iOS 18.0, *) { delegate = self } } } extension TabBarController: UITabBarControllerDelegate { func tabBarController(_ tabBarController: UITabBarController, animationControllerForTransitionFrom fromVC: UIViewController, to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? { return self } } extension TabBarController: UIViewControllerAnimatedTransitioning { func transitionDuration(using transitionContext: (any UIViewControllerContextTransitioning)?) -> TimeInterval { return .zero } func animateTransition(using transitionContext: any UIViewControllerContextTransitioning) { guard let view = transitionContext.view(forKey: .to) else { return } let container = transitionContext.containerView container.addSubview(view) transitionContext.completeTransition(true) } }
