The project builds successfully but unable to archive project on Xcode 26. error: "Command SwiftCompile failed with a nonzero exit code"

Setting up UITabAccessory via setBottomAccessory(_:animated:) causing recursion internally on iPhone Air which is leading into a crash. Sharing crash log & feedback below... crashlog.crash crash-feedback.json

On iOS 26 not able to control size of UITabBar. Sharing code below. Colour is applying correctly but somehow _UITabBarPlatterView which turns out as TabBar is not extending; leaving spaces on left, right & bottom sides. class CustomTabBar: UITabBar { override init(frame: CGRect) { super.init(frame: frame) backgroundColor = .red let firstItem = UITabBarItem(title: "Home", image: UIImage(systemName: "house"), tag: 0) let secondItem = UITabBarItem(title: "Search", image: UIImage(systemName: "magnifyingglass"), tag: 1) let thirdItem = UITabBarItem(title: "Profile", image: UIImage(systemName: "person.circle"), tag: 2) items = [firstItem, secondItem, thirdItem] selectedItem = firstItem } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } } class ViewController: UIViewController { let tabBar: CustomTabBar = { let tb = CustomTabBar() tb.translatesAutoresizingMaskIntoConstraints = false return tb }() override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .systemBackground view.addSubview(tabBar) NSLayoutConstraint.activate([ tabBar.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 25), tabBar.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -25), tabBar.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor) ]) } } when specifying height in CustomTabBar explicitly... func alignInternalSubViews() { subviews.forEach { subView in subView.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ subView.topAnchor.constraint(equalTo: topAnchor), subView.leadingAnchor.constraint(equalTo: leadingAnchor), subView.trailingAnchor.constraint(equalTo: trailingAnchor), subView.bottomAnchor.constraint(equalTo: bottomAnchor), subView.heightAnchor.constraint(equalToConstant: 62) ]) } } What should I need to do in order to get this capsule _UITabBarPlatterView and its subviews resize accordingly?

Hi, There is new cornerConfiguration API introduced for UIVisualEffectView mentioned in tutorial below. https://developer.apple.com/videos/play/wwdc2025/284/ But it is not available to use as of now. Using Xcode 26 Beta 2. Please get it fixed.
