Hi all, I've hit a reproducible issue where the presence of the SwiftUI instrument in a template prevents any data from being recorded, including from the other instruments in the same template. Removing the SwiftUI instrument immediately restores normal recording. Environment Host: macOS 26.4.1 (25E253), Mac mini Xcode / Instruments 26.4.1 (17E202) Device: iPhone 17, iOS 26.4.2 (23E261) (physical device, USB-attached) Symptom Recording the same app, same device, same session, only varying the template contents: SwiftUI template (as-is) => All lanes empty across the entire recording Same template with the SwiftUI instrument removed => Data collected normally (Time Profiler samples, Hangs, etc.) So it seems not an issue with the SwiftUI lanes specifically being empty — including the SwiftUI instrument appears to silence the entire recording. Steps to reproduce Open Instruments → pick the SwiftUI template (or build a custom template that includes the SwiftUI instrument alongside, e.g., Time Profiler). Target the device, attach to the running app. Record for ~10s, interact with the app. Stop. Result: every lane is empty. Edit the template, remove the SwiftUI instrument, re-record with no other changes. Result: normal data appears in the remaining instruments. Questions Is this a known regression in Instruments 26.4.1 on iOS 26.4.x? Is there a workaround to use the SwiftUI instrument on this OS combo (different Xcode build, runtime flag, entitlement)? Does it work for anyone on iOS 26.4.x + Xcode 26.4.1, or is everyone seeing this? I can file a Feedback if confirmed as a bug — wanted to check here first in case I'm missing a setup step. Thanks!

[Submitted as FB23998635] On iPhone, applying .tabBarMinimizeBehavior(.onScrollDown) to a SwiftUI TabView causes the native tab bar to briefly show the first declared tab before animating to the already-restored selection during app launch. The selected tab is persisted with @AppStorage and is already restored before the TabView is presented. The sample contains no explicit animations, transactions, navigation containers, loading states, asynchronous work, or post-launch selection changes. Removing .tabBarMinimizeBehavior(.onScrollDown) eliminates the launch animation entirely. Likewise, starting with .tabBarMinimizeBehavior(.never) and changing it to .onScrollDown after a one-second delay also eliminates the issue. The behavior reproduces with three simple tabs and a direct @AppStorage selection binding. ENVIRONMENT • iOS 26 & 27 REPRO STEPS Build and run the attached sample. Select the "Two" tab. Force-quit the app. Relaunch the app. Observe the tab bar during launch. ACTUAL The tab indicator initially appears on "One", the first declared tab, then animates to the correctly restored "Two" selection. EXPECTED The restored tab should be selected and stationary from the first visible frame, with no launch animation. SAMPLE CODE struct ContentView: View { private enum AppTab: String, Hashable { case one case two case three } @AppStorage("selectedGenericTab") private var selectedTab: AppTab = .three var body: some View { TabView(selection: $selectedTab) { Tab("One", systemImage: "1.circle", value: AppTab.one) { ReproTabContent(title: "One", color: .orange) } Tab("Two", systemImage: "2.circle", value: AppTab.two) { ReproTabContent(title: "Two", color: .blue) } Tab("Three", systemImage: "3.circle", value: AppTab.three) { ReproTabContent(title: "Three", color: .green) } } .tabBarMinimizeBehavior(.onScrollDown) } } private struct ReproTabContent: View { let title: String let color: Color var body: some View { ZStack { color.opacity(0.2) .ignoresSafeArea() Text(title) .font(.largeTitle) } } }

Feedback ID: FB23984230 This issue for some reason does not happen on my external 165 Hz display, but happens on my built-in MacBook Air display (60Hz). See attached example project: Contains two parts NSStatusItem with animation that triggers during ‘.onTapGesture()’ a window with ContentView that contains List and ScrollView while any ScrollView / List is in the view hierarchy in ContentView, triggering an animation in NSStatusItem (on a built-in MacBook display) is very choppy once removing ScrollView / List from view hierarchy from ContentView, animation in NSStatusItem is very smooth Project: Link macOS 26.5.2 (25F84)

The build itself is never in question — xcodebuild reports BUILD SUCCEEDED every time; only the subsequent simctl install step fails. What I'd like feedback on Is this a known issue with this specific Xcode 26.6 / iOS 26.5 Simulator runtime combination — both very recently installed, so possibly a fresh-install/first-boot bug? Is there a required build setting for this Xcode version not yet reflected in commonly-documented XcodeGen/xcodebuild recipes — e.g. an entitlements file now required even for simulator-only, no-team builds, or a different expected code-signing identity/format? Is Info.plist=not bound in the codesign -dv output actually abnormal for an app bundle (as opposed to a framework), and could that be the root cause simctl is choking on?

Hi everyone! After about 4-5 months of development, I released WatchBlocks v1.5 today. The project started as an experiment to answer a simple question: Could you build a real sandbox survival game that runs well on Apple Watch? It eventually grew into a cross-platform game supporting Apple Watch, iPhone, iPad, and Mac. Some of the technical challenges I enjoyed solving included: Optimizing rendering and gameplay for watchOS. Designing controls around the Digital Crown and the watch display. Building multiplayer across Apple platforms. Creating a content system that lets players make and share their own blocks, items, mobs, and biomes. The new update also transitions the game to a free-to-start model, making it easier for people to try it before deciding whether to unlock the full experience. I’d love to hear from other developers building for watchOS. It’s a platform that doesn’t get much attention for games, but I think there’s a lot of untapped potential. If anyone has questions about developing games for Apple Watch, I’m happy to answer them. App Store: https://apps.apple.com/us/app/watchblocks-craft-build/id6760209351

I am having a root TabView with tabs. One of the tabs has a TabBar with page style as the root view and each Page has a ScrollView. Unfortunately the scroll view get's clipped by the parent TabView size. But I want to make the ScrollView content to go behind the root TabView's tab bar like it would work if I would have the ScrollView as direct child to the root TabBar I tried using ignoreSafeArea on the page style TabView and there are other weird bugs, it stops reacting to the Binding pageIndex I am having as a State. The custom page index view disappears Sample code: https://github.com/BProg/TabViewScrollViewBug.git

Can somebody tell me if I'm doing something wrong or SwiftUI's scrollTo(id:anchor:) just doesn't work if the ScrollView is scrolling? I have a trivial example that demonstrates the issue: import SwiftUI @main struct MyApp: App { var body: some Scene { WindowGroup { ContentView() } } } struct Item: Identifiable { let id = UUID() let timestamp: Date let text: String } struct ContentView: View { @State private var items: [Item] = (0...10_000).map{ .init(timestamp: Date(), text: "Row \($0)") } @State private var scrollPosition = ScrollPosition(idType: Item.ID.self) @State private var newMessage: String = "" var body: some View { ScrollView { LazyVStack { ForEach(items) { item in ItemView(item: item) } }.scrollTargetLayout() } .defaultScrollAnchor(.bottom, for: .initialOffset) .scrollPosition($scrollPosition, anchor: .bottom) .safeAreaBar(edge: .bottom) { HStack { TextField("Type here", text: $newMessage, axis: .vertical) .textFieldStyle(.roundedBorder) Button("Send", action: { let trimmed = newMessage.trimmingCharacters(in: .whitespacesAndNewlines) guard !trimmed.isEmpty else { return } newMessage = "" items.append(.init(timestamp: .now, text: trimmed)) withAnimation(.smooth) { scrollPosition.scrollTo(id: items.last!.id, anchor: .bottom) } }) }.padding() } } } struct ItemView: View { let item: Item var body: some View { VStack(alignment: .leading) { Text(item.text) Text(item.timestamp.formatted()) }.padding() .frame(maxWidth: .infinity, alignment: .leading) .background(Color(red: .random(in: 0...1), green: .random(in: 0...1), blue: .random(in: 0...1))) } } #Preview { ContentView() }

Hi, We have found a nasty issue with SwiftUI List and Equatable reference types. In such scenarios List might resurface stale objects from some internal cache when inserting new equal instances, which can lead to outdated cells on screen. Detailed information can be found in our bug report (FB23923342). Since List is quite a widespread component we thought dropping a few lines here in addition to our report could be helpful, especially if you have been bitten by this issue in the past.

Hello! I have experienced a weird bug in iOS 26 Beta (8) and previous beta versions. The safe area inset is not correctly aligned with the keyboard toolbar on real devices and simulators. When you focus a new textfield the bottom safe area is correctly placed aligned the keyboard toolbar. On real devices the safe area inset view is covered slightly by the keyboard toolbar, which is even worse than on the simulator. Here's a clip from a simulator: Here's the code that reproduced the bug I experienced in our app. #Preview { NavigationStack { ScrollView { TextField("", text: .constant("")) .padding() .background(Color.secondary) TextField("", text: .constant("")) .padding() .background(Color.green) } .padding() .safeAreaInset(edge: .bottom, content: { Color.red .frame(maxWidth: .infinity) .frame(height: 40) }) .toolbar { ToolbarItem(placement: .keyboard) { Button {} label: { Text("test") } } } } }

Environment: iOS Version: iOS 27.0 Framework: ActivityKit Xcode Version: Xcode 26.1 Issue Description: In iOS 27, Live Activities fail to adapt to the system colorScheme. Regardless of whether the system theme is set to Light or Dark mode, @Environment(.colorScheme) inside the Live Activity view always returns .dark. This behavior worked as expected on iOS 26, where the Live Activity correctly responded to light/dark mode changes and rendered the appropriate theme. Expected Behavior: The Live Activity view should respect the system's current colorScheme (returning .light when the system is in Light Mode) on iOS 27, consistent with the behavior on iOS 26. Actual Behavior: The Live Activity view strictly defaults to .dark mode on iOS 27, even when the device is explicitly set to Light Mode. struct LockScreenView<T: BaseLiveActivityAttributes>: View { let context: ActivityViewContext<T> @Environment(\.colorScheme) var colorScheme var isLight: Bool { colorScheme == .light } var body: some View { Color(isLight ? .white : .black) .overlay(alignment: .topTrailing) { VStack(alignment: .trailing, spacing: 2) { Text("colorScheme: \(String(describing: colorScheme))") } .font(.system(size: 9, weight: .bold, design: .monospaced)) .foregroundColor(.yellow) .padding(4) .background(Color.black.opacity(0.6)) .cornerRadius(4) .padding(.trailing, 8) .padding(.top, 4) } } } Any insights or workarounds would be greatly appreciated. Thanks!

When switching to a SwiftUI app (built with Xcode 26.5) from an app with an active keyboard, the target app's tab bar incorrectly floats above the keyboard safe area. This layout issue occurs even though the target app does not display a keyboard and contains only a tab bar and scroll views.

I'm using PDFKitView: NSViewRepresentable to present the pdf page in SwiftUI. Seems we already have some useful built-in functions in the context menu. However, the highlight manipulation functions are not functional - I can neither delete the highlight annotation nor change the color/type of the current pointed highlight annotation. The "Add Note" and other page display changing functions work well.

Feedback ID: FB23086400 On iOS 27 beta 1, .scrollEdgeEffectStyle(.soft, for: .top) on a List underneath a custom .safeAreaBar(edge: .top) no longer renders the progressive fade-blur. The top edge is fully transparent — scrolled rows pass under the bar with no visual treatment at all, as if scrollEdgeEffectDisabled() had been applied. What I've verified so far: .hard renders correctly in the exact same hierarchy; only .soft is affected. The same binary works correctly on iOS 26.x Xcode preview. I'm building with Xcode 26.3 (iOS 26 SDK). Minimal reproduction: import SwiftUI struct EdgeEffectRepro: View { enum Style: String, CaseIterable, Identifiable { case automatic, soft, hard var id: Self { self } var value: ScrollEdgeEffectStyle { switch self { case .automatic: .automatic case .soft: .soft case .hard: .hard } } } @State private var style: Style = .soft @State private var useSystemBarOnly = false var body: some View { NavigationStack { List(0..<60, id: \.self) { i in Text("Row \(i)") .frame(maxWidth: .infinity, alignment: .leading) .listRowBackground( i.isMultiple(of: 2) ? Color.orange.opacity(0.45) : Color.teal.opacity(0.45) ) } .scrollIndicators(.hidden) .scrollEdgeEffectStyle(style.value, for: .top) .safeAreaBar(edge: .top) { if !useSystemBarOnly { VStack(spacing: 8) { HStack { Text("Custom Top Bar") .font(.system(size: 28, weight: .bold)) Spacer() } HStack { Text("Second row (e.g. date range picker)") .font(.caption) .foregroundStyle(.secondary) Spacer() } } .padding(.horizontal) } } .safeAreaInset(edge: .bottom) { VStack(spacing: 8) { Picker("Edge effect style", selection: $style) { ForEach(Style.allCases) { Text($0.rawValue).tag($0) } } .pickerStyle(.segmented) Toggle("System bar only (control group)", isOn: $useSystemBarOnly) .font(.caption) } .padding() .background(.regularMaterial) } .navigationTitle("EdgeEffect Repro") .navigationBarTitleDisplayMode(.inline) } } } Steps: run on iOS 27 beta 1, set the picker to soft, scroll rows under the bar. Expected: fade-blur as on iOS 26. Actual: fully transparent. Switch to hard: renders fine.

Hello, Could someone from Apple clarify the support and behavior of the UIDesignRequiresCompatibility property? The UIDesignRequiresCompatibility documentation states that this property will be ignored for builds targeting iOS 27 or later. I have a couple of questions: Does "builds targeting iOS 27 or later" refer to an app that was built using Xcode 27 or later? iOS 27 is expected to be released in Fall 2026. Suppose that after iOS 27 is released, I create a new build using Xcode 26, with UIDesignRequiresCompatibility set to true, and install that build on an iOS 27 device. Will UIDesignRequiresCompatibility still be honored in this scenario, or will it be ignored and the app will use the Liquid Glass UI? Thanks!

I have a ScrollView with a LazyVStack with Sections. I initialize the ScrollView with a scroll position but the ScrollView starts with the first row at the top. Am I doing something wrong or is this just a bug in ScrollView? It seems to work fine if I do not use Section. struct ContentView: View { @State var scrollPosition: ScrollPosition init() { var p = ScrollPosition(idType: Int.self) p.scrollTo(id: 500, anchor: .top) scrollPosition = p } var body: some View { ScrollView { LazyVStack { ForEach(0..<sectionCount, id: \.self) { j in Section { ForEach(0..<rowCount, id: \.self) { i in RowView(text: "\(j)/\(i) [\(j*rowCount+i)]") .id(j*rowCount+i) } } header: { HeaderView(title: "\(j)") } } } .scrollTargetLayout() } .scrollPosition($scrollPosition) } }

Hello everyone, I am encountering an inconsistent typography behavior when developing for WidgetKit. Specifically, there is no native serif font fallback for Chinese characters (CJK) in the Widget environment, whereas Latin characters are fully supported. When using the .serif design modifier in SwiftUI: Text("Hello 世界").font(.system(size: 16, design: .serif)) English/Latin characters ("Hello"): System correctly renders using the pre-installed serif font (New York). Chinese characters ("世界"): System ignores the .serif design and falls back to the default sans-serif font (PingFang SC). Can I find any pre-installed native serif font for CJK in iOS that I can reliably invoke within my Widget Extension without bundling .ttf files? If not, do you have plans to map Font.design(.serif) to a pre-installed CJK serif font in future iOS releases so I can maintain design consistency across my localized widgets? Thank you for any insights or recommended workarounds.

We're getting user reports that the App Store rating prompt appears repeatedly — one user says they're prompted roughly every day, and that they still get the prompt after they've already left a rating. This contradicts the documented behavior, so I want to check whether others are seeing the same thing or whether there's a known regression. What the docs say should happen The system limits display to 3 occurrences per app within a 365-day period. For a user who has already rated/reviewed, StoreKit should only display again if the app version is new and more than 365 days have passed since their previous review. Has anyone else experience it?

I want to detect when the user stopped touching the screen. But I want it to be in a vertical ScrollView and a DragGesture isn't recognized when the view is scrolled vertically. I'm guessing this is because there wasn't anything dragged, since the view moved along with the user's finger. import SwiftUI struct TestView: View { var body: some View { ScrollView { VStack(spacing: 0) { Rectangle() .foregroundStyle(.green) .frame(height: 700) } } .gesture(DragGesture().onEnded({ _ in print("Drag gesture ended") })) } } How should I go about detecting when the user lifted their finger off the screen on a scrollview?

i've been struggling to get the SwiftUI instrument to work during the betas. It never produces any results on simulator, while on device it throws an error which prevents any results from other instruments from appearing. the error is: Failed to stop recording session: Data Providers emitted errors: Required I've tried on my iPad Pro 11-inch (M4) (iPadOS27 beta 3), and iPhone 17 Pro Max (iPadOS27 beta 2). And I get the same result running from my mac studio & MacBook air. Is this a known thing? cheers, Mike
