Here to say that @Mwloczko's solution worked for me as well! My problem was that the main target had a deployment of iOS 18.2 and my extension was iOS 26, while my simulator is running 18.5.. Having set everything to a target of iOS 17 - everything started working like a charm again.

Came here to say thank you — this issue is still present, and your solution helped! Instead of going to the next image, my TabView (nested in a VStack that has .ignoresSafeArea(edges: .vertical)) shifted the image up and then refused to switch from there on — unless you manually swipe. It only seems to happen when the TabView extends beyond the safe area. Otherwise, everything works fine even without the fix. Here’s the setup: VStack(alignment: .leading, spacing: 0) { TabView { ForEach(viewModel.state.backgroudImages, id: \.self) { imageResource in Image(imageResource) .resizable() .scaledToFill() } } .tabViewStyle(PageTabViewStyle()) .indexViewStyle(PageIndexViewStyle(backgroundDisplayMode: .always)) .background(.red.opacity(0.001)) // This line did the trick // Other content } .ignoresSafeArea(edges: .vertical) .dynamicTypeSize(...DynamicTypeSize.large) .toolbar { toolbarItems } .navigationTitle("Get AppName Pro") .navigationBarTitleDisplayMode(.inline) .background(.red.opacity(0.001)) — just that — and the switching works perfectly: Without it, tapping on the PageIndex causes this broken behavior:
