I have defined a colour in the asset catalog of my widget extension. I am using this widget extension for my live activity. This colour has both an ‘Any’ and ‘Dark’ appearance. I am using this colour in the activityBackgroundTint modifier for my main live activity view (the ActivityPreviewViewKind is content, visible on the Lock Screen). In light mode, this works as expected, but in dark mode, the background colour is still the light mode variant. The content within the view changes according to whether the system is in light or dark mode, but the background does not. I want to avoid using just the background modifier instead of activityBackgroundTint, as this does not colour the ‘Allow Live Activities from …’ and ‘Clear’ sections, which is undesirable. I have also tried reading colorScheme from the environment and choosing the light or dark mode colour variant accordingly, but this workaround also doesn’t completely work. If you keep changing from light and dark mode (via the Settings app, not the control centre, for whatever reason), the background colour actually becomes the opposite of the expected value in this case. Is there a workaround that can help me achieve what I want, or am I simply doing something wrong? I have filed a bug report under FB15148099

There seems to be a misalignment when using VoiceOver and selecting the leading/trailing regions in the expanded presentation for Live Activities. This is demonstrated with an extremely basic sample project, where the expanded region is defined by the following code: DynamicIsland { DynamicIslandExpandedRegion(.leading) { Text("Leading") } DynamicIslandExpandedRegion(.trailing) { Text("Trailing") } DynamicIslandExpandedRegion(.bottom) { Text("Bottom \(context.state.emoji)") } } Is this simply a bug or am I doing something incorrectly/is there a workaround?

I’m seeing a visual glitch with toolbar buttons when building with Xcode 26 for iOS 26. During transitions (both pushing in a NavigationStack and presenting a .sheet with its own NavigationStack), the toolbar button briefly flashes the wrong background colour (black in dark mode, white in light mode) before animating to the correct Liquid Glass appearance. This happens even in a minimal example and only seems to affect system toolbar buttons. A custom view with .glassEffect() doesn’t have the issue. I’ve tried: .tint(...), UINavigationBarAppearance/UIToolbarAppearance, and setting backgrounds on hosting/nav/window but none of those made any difference. Here’s a minimal reproducible example: import SwiftUI struct ContentView: View { @State private var showingSheet = false var body: some View { NavigationStack { List { NavigationLink("Push (same stack — morphs)") { DetailView() } Button("Sheet (separate stack — flashes)") { showingSheet = true } } .navigationTitle("Root") .scrollContentBackground(.hidden) .background(.gray) .toolbar { ToolbarItem(placement: .topBarTrailing) { Button("Action") {} } } .sheet(isPresented: $showingSheet) { SheetView() } } } } struct DetailView: View { var body: some View { Text("Detail (same stack)") .frame(maxWidth: .infinity, maxHeight: .infinity) .background(.gray) .navigationTitle("Detail") .toolbar { ToolbarItem(placement: .topBarTrailing) { Button("Action") {} } } } } struct SheetView: View { var body: some View { NavigationStack { Text("Sheet (separate stack)") .frame(maxWidth: .infinity, maxHeight: .infinity) .background(.gray) .navigationTitle("Sheet") .toolbar { ToolbarItem(placement: .topBarTrailing) { Button("Action") {} } } } } } Has anyone else seen this or found a workaround outside of disabling this background completely with .sharedBackgroundVisibility(.hidden)?

I’ve been investigating a noticeable animation hitch when interactively dismissing a sheet over a SwiftUI screen with moderate complexity. This was not the case on iOS 18, so I’m curious if others are seeing the same on iOS 26 or have found any mitigations. When dismissing a sheet via the swipe gesture, there’s a visible hitch right after lift-off. The hitch comes from layout work in the underlying view (behind the sheet) The duration scales with the complexity of that view (e.g. number of TextFields/layout nodes) The animation for programmatic dismiss (e.g. tapping a “Done” button) is smooth, although it hangs for a similar amount of time before dismissing, so it appears that the underlying work still happens. SwiftUI is not reevaluating the body during this (validated with Self._printChanges()), so that is not the cause. Using Instruments, the hitch shows up as a layout spike on the main thread: 54ms UIView layoutSublayersOfLayer 54ms └─ _UIHostingView.layoutSubviews 38ms └─ SwiftUI.ViewGraph.updateOutputs 11ms ├─ partial apply for implicit closure #1 in closure #1 │ in closure #1 in Attribute.init<A>(_:) 4ms └─ -[UIView For the same hierarchy with varying complexity: ~3 TextFields in a List: ~25ms (not noticeable) ~20+ TextFields: ~60ms (clearly visible hitch) The same view hierarchy on iOS 18 did not exhibit a visible hitch. I’ve tested this on an iOS 26.4 device and simulator. I’ve also included a minimum reproducible example that illustrates this: struct ContentView: View { @State var showSheet = false var body: some View { NavigationStack { ScrollView { ForEach(0..<120) { _ in RowView() } } .navigationTitle("Repro") .toolbar { ToolbarItem(placement: .topBarTrailing) { Button("Present") { showSheet = true } } } .sheet(isPresented: $showSheet) { PresentedSheet() } } } } struct RowView: View { @State var first = "" @State var second = "" var body: some View { VStack(alignment: .leading, spacing: 12) { Text("Row") .font(.headline) HStack(spacing: 12) { TextField("First", text: $first) .textFieldStyle(.roundedBorder) TextField("Second", text: $second) .textFieldStyle(.roundedBorder) } HStack(spacing: 12) { Text("Third") Text("Fourth") Image(systemName: "chevron.right") } } } } struct PresentedSheet: View { @Environment(\.dismiss) private var dismiss var body: some View { NavigationStack { List {} .navigationTitle("Swipe To Dismiss Me") .toolbar { ToolbarItem(placement: .topBarTrailing) { Button("Done") { dismiss() } } } } } } Is anyone else experiencing this and have any mitigations been found beyond reducing view complexity?
