The Apple sample code Landmarks project uses a LazyVStack inside a ScrollView. For a List, which you want, you will need to: Put the ContainerView in the List as the first row. Set the listRowBackground of the ContainerView to EmptyView(). Set the listStyle to plain, for listRowBackground to work. Add .background(alignment: .top) { with the background you want for the ContainerView. Use readFrame() to dynamically adjust the height of the background to match the maxY position of the ContainerView. import SwiftUI struct ListHeaderScene: View { @State var headerRect: CGRect? var headerHeight: CGFloat { headerRect?.maxY ?? 0 } var body: some View { List { ContainerView() .readFrame { headerRect = $0 } .listRowSeparator(.hidden) .listRowBackground(EmptyView()) Section(Section Title) { Text(Row 1) Text(Row 2) } } .listStyle(.plain) .background(alignment: .top) { // You can swap this for an image or whatever. Color.purple .frame(height: headerHeight) .ignoresSafeArea() } } } struct ContainerView: View { var

I investigated further and found your answer! UndoManager is the API in the Foundation framework for undo/redo and SwiftUI has an environment value for that undoManager. This example disables undo on TextField on Mac struct ContentView: View { @Environment(.undoManager) var undoManager: UndoManager? var body: some View { VStack { TextField(Test, text: $text) } .task { undoManager?.disableUndoRegistration() } } } Let me know if this answers your question  Travis Trotto - DTS Engineer

Sorry for not replying earlier. No, I'm afraid that info isn't what I'm looking for. The thing that I'd like to understand really is, specifically: how to use the built-in undo support of SwiftUI TextField views, if any. Hopefully you're able to get details on this somehow!

Also confirmed this is still broken in iOS 26.3 (23D127). My feedback is FB21078443 filed Nov 2025. If anyone can’t repro it, here’s a minimal example. Tap a color, then swipe back from the left edge—the source view will disappear after the transition. Easier to repro on physical device, but also possible in sim with a solid swipe. import SwiftUI struct ContentView: View { @Namespace private var namespace private let colors: [Color] = [.red, .blue] var body: some View { NavigationStack { VStack(spacing: 16) { ForEach(colors.indices, id: .self) { index in NavigationLink(value: index) { RoundedRectangle(cornerRadius: 16) .fill(colors[index]) .frame(maxWidth: .infinity, minHeight: 200, maxHeight: 200) .matchedTransitionSource(id: index, in: namespace) } .buttonStyle(.plain) } } .padding(20) .navigationTitle(Zoom Transition Issue) .navigationSubtitle(Tap card, then swipe back from left edge) .navigationDestination(for: Int.self) { index in Rectangle() .fill(colors[index]) .ignoresSafeArea() .navigationTr

I am going to suggest that your issue is more structural than a Bluetooth connection problem if even print(App initializing) is not printing. Once you get that working (perhaps start with a clean Hello world! project to make sure your code is running. And then you can add the Bluetooth functionality to it using examples. Unfortunately our sample projects are a bit dated, and outside the watchOS sample Interacting with Bluetooth peripherals during background app refresh, we don't have any SwiftUI examples that demonstrate CoreBluetooth. Currently, the CoreBluetooth framework is not fully compatible with SwiftUI, and requires the use of @UIApplicationDelegateAdaptor var delegate: ApplicationDelegate and handle your CoreBluetooth logic in a UIKit class. In the above example, you will find an iOS target BARBluetooth, which will show how the SwiftUI/UIKit integration is handled. (do not consider the code there as a full example though, as that is a specific app that only accompanies the
