TabView inside NavigationStack is abnormal when using Xcode 26. The y deviation is about 14. But it is right when using Xcode 16.4. It is also right without NavigationStack. import SwiftUI struct ContentView: View { private enum Tab: Hashable, CaseIterable { case a case b } @State private var currentTab: Tab = .a @State private var path: NavigationPath = NavigationPath() var body: some View { NavigationStack(path: $path) { TabView(selection: $currentTab) { ForEach(Tab.allCases, id: \.self) { tab in switch tab { case .a: Color.blue // .offset(y: -14) case .b: Color.yellow } } } .tabViewStyle(.page(indexDisplayMode: .never)) .ignoresSafeArea(.all) } } }

I am using ".navigationTransition(ZoomNavigationTransition.zoom(sourceID: xxx, in: xxx))" to zooms the appearing view from a source view . When the appearing view dismissed, I can only click other view after a delay . It seems that the transition is not finished immediately when the appearing view dismissed . After a delay, the transition finished, than I can click other view. struct ContentView: View { @State private var path: NavigationPath = NavigationPath() @Namespace private var namespace var body: some View { NavigationStack(path: $path) { VStack(spacing: 0) { ForEach(["aaa", "bbb"], id: \.self) { string in Text(string) .frame(width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height / 2) .contentShape(Rectangle()) .onTapGesture { path.append(string) } .matchedTransitionSource(id: string, in: namespace) } } .navigationDestination(for: String.self, destination: { route in Text(route) .navigationTransition(ZoomNavigationTransition.zoom(sourceID: route, in: namespace)) }) } } } When using sheet on appearing view, It seems that the transition is finished immediately when the appearing view dismissed. extension String: Identifiable { public var id: String { return self } } struct ContentView: View { @State private var path: NavigationPath = NavigationPath() @Namespace private var namespace @State private var stringToSheet: String? var body: some View { NavigationStack(path: $path) { VStack(spacing: 0) { ForEach(["aaa", "bbb"], id: \.self) { string in Text(string) .frame(width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height / 2) .contentShape(Rectangle()) .onTapGesture { stringToSheet = string } .matchedTransitionSource(id: string, in: namespace) } } .sheet(item: $stringToSheet) { newValue in Text(newValue) .navigationTransition(ZoomNavigationTransition.zoom(sourceID: newValue, in: namespace)) } } } }
