Hide standard window buttons
How do I permanently hide the standard window buttons(Buttons on top left; close, minimize and zoom) In my app, I hide the standard buttons and put my own custom buttons. Some users have reported that the standard buttons appear again making the app look buggy and confuses the users At present I use following code to remove the buttons standardWindowButton(.closeButton)?.removeFromSuperview() standardWindowButton(.miniaturizeButton)?.removeFromSuperview() standardWindowButton(.zoomButton)?.removeFromSuperview() } I have to call this code from multiple places like on window initialization, when appearance changes and when the window size changes. I tried creating window without the titled stylemask, but it has other down sides like the standard window decoration is entirely skipped by the system. The resizing also is unpredictable. My question is, what is the right way to remove/hide the standard window buttons?

Handling View Creation for Heterogeneous Data
In my project (an Package), I have created an Manager (can be classified as an ViewModel) that will handle state updates throughout the Package Component view: Note: The code is simplified for better understanding and to focus on principles behind things I did. The manager does complex things during state updates. public class ComponentManager: ObservedObject { @Published var rows: [any RowProtocol] = [] func updateState(_ newState: any RowProtocolData, id: String) { guard let index = rows.firstIndex(where: { $0.id == id }) else { return } rows[index].updateState(newState) } func getState(id: String) -> any RowProtocolData? { guard let index = rows.firstIndex(where: { $0.id == id }) else { return nil } return rows[index].state } } The RowProtocol is defined as follows: public protocol RowStateProtocol {} public protocol RowProtocol: Identifiable { associatedtype State: RowStateProtocol associatedtype RowView: View var id: String { get } var state: State { get } func updateState(_ newState: State) @MainActor @ViewBuilder func renderRow() -> RowView } extension RowProtocol { func updateState(_ newState: any RowProtocolData) { guard let newState = newState as? State else { return } self.updateState(newState) } } Then in Component View, I need to render the rows based on the underlying type of the row, this where the renderRow() comes in: struct ComponentView: View { @ObservedObject var manager: ComponentManager var body: some View { List { ForEach(manager.rows, id: \.id) { row in HStack { // This HStack prevent List from initing all rows due to AnyView. AnyView(row.renderRow()) } } } } } The row views will be accepting binding to the state of the row and update their state, let says we have a TextRow and a ToggleRow: struct TextRow: RowProtocol { var id: String var state: TextRowState func updateState(_ newState: TextRowState) { self.state = newState } } struct ToggleRow: RowProtocol { var id: String var state: ToggleRowState func updateState(_ newState: ToggleRowState) { self.state = newState } } In this, offcourse we cannot create an binding directly to the state of the row, since the state are through the manager and the row data won't have access to the manager. So I created an property wrapped that use the closures passed by the manager into environment to create the binding and an view that will give the binding to the content view: extenstion EnvironmentValues { @Entry internal var getState: (String) -> any RowStateProtocol? @Entry internal var updateState: (any RowStateProtocol, String) -> Void } @propertyWrapper struct RowStateBinding<State: RowStateProtocol & Equatable>: DynamicProperty { @Environment(\.getState) private var getState @Environment(\.updateState) private var updateState private let id: String init(id: String) { self.id = id } var wrappedValue: State { get { getState(id) as! State } nonmutating set { if wrappedValue != newValue { // only update for an new change, since set can be triggered for any number of reasons. updateState(newValue, id) } } } var projectedValue: Binding<State> { Binding( get: { self.wrappedValue }, set: { newValue in self.wrappedValue = newValue } ) } } struct RowStateBindingView<Content: View, State: RowStateProtocol & Equatable>: View { @RowStateBinding<State> private var state: State private let content: (Binding<State>) -> Content init(id: String, @ViewBuilder content: @escaping (Binding<State>) -> Content) { self._state = RowStateBinding(id: id) self.content = content } var body: some View { content($state) } } and in the renderRows: struct TextRowView: View { @Binding var text: TextRowState var body: some View { TextField("Enter text", text: $text.text) } } extension TextRow { func renderRow() -> some View { RowStateBindingView(id: id) { state in TextField("Enter text", text: state.text) } } } struct ToggleRowView: View { @Binding var state: ToggleRowState var body: some View { Toggle("Toggle", isOn: $state.isOn) } } extension ToggleRow { func renderRow() -> some View { RowStateBindingView(id: id) { state in Toggle("Toggle", isOn: state.isOn) } } } This way, I can adopt any view as an row view and most importantly, the view can be completely independent of the manager and used as an standalone view. Also clients of the library can create their own custom rows by just conforming to the RowProtocol and creating the view for it, without worrying about how the state management works. The manager will handle all the state updates. I prefer using stucts over classes for rows and states, since its easier to manage state updates. What do you think about this approach? Do you see any potential issues with this? Is there a better way to achieve this?

Crash occured in UIDatePicker Calendar type
I am encountering a consistent, reproducible crash in our app when presenting a UIDatePicker configured with the calendar style. The crash triggers every single time the picker is invoked and points directly to the modern date picker's internal UICollectionView. The Exception: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UICollectionView internal inconsistency: attempted to set layout with the collection view requiring a reload' let datePicker = UIDatePicker() datePicker.datePickerMode = .date datePicker.preferredDatePickerStyle = .compact This crash is occuring in inline style too when I try to open the calendar. I tried this in other apps. It works fine. I didn't override any collectionView layouts

Summary of iOS/iPadOS 26 UIKit bugs related to UISearchController & UISearchBar using scope buttons
All of these issues appear when the search controller is set on the view controller's navigationItem and the search controller's searchBar has its scopeButtonTitles set. So far the following issues are affecting my app on iOS/iPadOS 26 as of beta 7: When the scopeBarActivation of UISearchController is set to .onSearchActivation, the preferredSearchBarPlacement of the navigationItem is set to .integratedButton, and the searchBarPlacementAllowsToolbarIntegration is set to false (forcing the search icon to appear in the nav bar), on both iPhones and iPads, the scope buttons never appear. They don't appear when the search is activated. They don't appear when any text is entered into the search bar. FB19771313 I attempted to work around that issue by setting the scopeBarActivation to .manual. I then show the scope bar in the didPresentSearchController delegate method and hide the scope bar in the willDismissSearchController. On an iPhone this works though the display is a bit clunky. On an iPad, the scope bar does appear via the code in didPresentSearchController, but when any scope bar button is tapped, the search controller is dismissed. This happens when the app is horizontally regular. When the app on the iPad is horizontally compact, the buttons work but the search bar's text is not correctly aligned within the search bar. Quite the mess really. I still need to post a bug report for this issue. But if issue 1 above is fixed then I don't need this workaround. When the scopeBarActivation of UISearchController is set to .onSearchActivation, the preferredSearchBarPlacement of the navigationItem is set to .stacked, and the hidesSearchBarWhenScrolling property of the navigationItem is set to false (always show the search bar), and this is all used in a UITableViewController, then upon initial display of the view controller on an iPhone or iPad, you are unable to tap on the first row of the table view except on the very bottom of the row. The currently hidden scope bar is stealing the touches. If you activate and then cancel the search (making the scope bar appear and then disappear) then you are able to tap on the first row as expected. The initially hidden scope bar also bleeds through the first row of the table. It's faint but you can tell it's not quite right. Again, this is resolved by activating and then canceling the search once. FB17888632 When the scopeBarActivation of UISearchController is set to .onSearchActivation, the preferredSearchBarPlacement of the navigationItem is set to integrated or .integratedButton, and the toolbar is shown, then on iPhones (where the search bar/icon appears in the toolbar) the scope buttons appear (at the top of the screen) the first time the search is activated. But if you cancel the search and then activate it again, the search bar never appears a second (or later) time. On an iPad the search bar/icon appears in the nav bar and you end up with the same issue as #1 above. FB17890125 Issues 3 and 4 were reported against beta 1 and still haven't been fixed. But if issue 1 is resolved on iPhone, iPad, and Mac (via Mac Catalyst), then I personally won't be affected by issues 2, 3, or 4 any more (but of course all 4 issues need to be fixed). And by resolved, I mean that the scope bar appears and disappears when it is supposed to each and every time the search is activated and cancelled (not just the first time). The scope bar doesn't interfere with touch events upon initial display of the view controller. And there are no visual glitches no matter what the horizontal size class is on an iPad. I really hope the UIKit team can get these resolved before iOS/iPadOS 26 GM.

UIView wrapper around a View
I couldn't decide whether to post this question here or in SwiftUI Q&A as there's a lot of overlaps. We're trying to create something similar to UIViewRepresentable for UIKit. This might not work for complicated cases where the View has many pieces but as long as it works for simple cases, we're happy. The only problem right now is figuring out the correct height. Currently, the height anchor is assigned to CGFloat.greatestFiniteMagnitude, which works but when inspecting the layout in View Hierarchy, it appears the wrapped view is getting stretched all the way down. Also, sometimes View Hierarchy isn't able to draw the wrapped View and I'm unsure if it's a problem of View Hierarchy or our implementation. final public class SwiftUIConfigurationContainerView<T: View>: UIView { private var contentView: UIView? public override var intrinsicContentSize: CGSize { contentView?.intrinsicContentSize ?? super.intrinsicContentSize } private var preferredContentSize: CGSize? public init(@ViewBuilder _ content: @escaping () -> T) { super.init(frame: .zero) setUpContentView(content) } @available(*, unavailable) required init?(coder: NSCoder) { return nil } private func setUpContentView(_ content: @escaping () -> T) { let contentView = UIHostingConfiguration { [weak self] in VStack(spacing: .zero) { content() .onGeometryChange(for: CGSize.self, of: \.size) { size in self?.preferredContentSize = size self?.invalidateIntrinsicContentSize() } .frame(maxWidth: .infinity, alignment: .center) Spacer(minLength: .zero) } } .minSize(width: .zero, height: .zero) .margins(.all, .zero) .makeContentView() self.contentView = contentView addSubview(contentView) contentView.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ contentView.leadingAnchor.constraint(equalTo: leadingAnchor), contentView.trailingAnchor.constraint(equalTo: trailingAnchor), contentView.topAnchor.constraint(equalTo: topAnchor), contentView.heightAnchor.constraint(equalToConstant: CGFloat.greatestFiniteMagnitude), ]) } }

SwiftUI ​Charts: In iOS 27, annotation overlays exceed the bounds of an annotation
I'm seeing a regression in SwiftUI Charts on iOS 27 beta 1. Any view placed inside a BarMark's overlay annotation no longer receives the size of the parent BarMark. It collapses to zero, so any content sized from geo.size (e.g. a Rectangle meant to fill the bar) renders empty or incorrectly. Expected: The GeometryReader reports the BarMark's rendered width/height, and the Rectangle fills the BarMark (this is the behavior in iOS 26 and earlier). Actual: On iOS 27 beta 1, geo.size is effectively zero, so the overlay content has an extremely small size. I suspect this could be a small bug with the new ContentBuilder / ViewBuilder changes but that's just a hunch. Here's a code sample which reproduces the issue. // MARK: - Mock Data Models struct ScheduleSeries: Identifiable { let id = UUID() let data: [ScheduleItem] } struct ScheduleItem: Identifiable { let id = UUID() let startDate: Date let startHour: Double let endHour: Double let secondaryText: String? } // MARK: - Minimal Reproducible Example struct ContentView: View { // Generate two consecutive days for the mock data let mockSchedule: [ScheduleSeries] = [ ScheduleSeries(data: [ ScheduleItem( startDate: Date(), startHour: 9.0, endHour: 11.5, secondaryText: "Morning Event" ), ScheduleItem( startDate: Calendar.current.date(byAdding: .day, value: 1, to: Date())!, startHour: 13.0, endHour: 16.0, secondaryText: "Afternoon Event" ) ]) ] var body: some View { VStack(alignment: .leading) { Text("FB: Annotation Sizing Bug") .font(.headline) .padding(.bottom, 8) Text("Expected: The gray Rectangle should stretch to fill the BarMark.\nActual: GeometryReader/Annotation fails to size to the parent BarMark.") .font(.caption) .foregroundColor(.secondary) .padding(.bottom) Chart(mockSchedule) { series in ForEach(series.data, id: \.startDate) { element in BarMark( x: .value("Day", element.startDate, unit: .day, calendar: .current), yStart: .value("Start", element.startHour), yEnd: .value("End", element.endHour), width: .ratio(0.99) ) .annotation(position: .overlay, alignment: .topLeading) { item in ZStack { VStack(alignment: .leading, spacing: 0) { // BUG DEMONSTRATION: // This GeometryReader and Rectangle previously filled the BarMark, but in Xcode 27 it does not GeometryReader { geo in Rectangle() .fill(Color.black.opacity(0.15)) .frame(width: geo.size.width, height: geo.size.height) } } .foregroundColor(.white) .font(.caption2) } } } } .chartYScale(domain: 0...24) // Lock the Y-axis to a 24-hour scale } .padding() } } Environment: Xcode 27 beta 1 / iOS 27 beta 1 Reproduces on device and Simulator Worked as expected on iOS 26 and earlier Here's what the issue looks like in our app with zero code changes: iOS 26 iOS 27 I've filed a feedback report (FB23016343) with a sample project attached. Has anyone else hit this, or found a workaround for sizing overlay annotation content to a BarMark in iOS 27? Thanks!

How to detect backspace in SwiftUI TextField without falling back to UIViewRepresentable?
I'm building a multi-box PIN/OTP input in SwiftUI. In UIKit, I used UITextFieldDelegate to detect backspace presses on an empty field to move focus backward. SwiftUI’s .onChange(of: text) only triggers when text is actually deleted, completely missing backspaces on an already empty field. Is there a pure SwiftUI way to handle this now, or are we still forced to wrap UITextField via UIViewRepresentable?

Source view disappearing when interrupting a zoom navigation transition
When I use the .zoom transition in a navigation stack, I get a glitch when interrupting the animation by swiping back before it completes. When doing this, the source view disappears. I can still tap it to trigger the navigation again, but its not visible on screen. This seems to be a regression in iOS 26, as it works as expected when testing on iOS 18. Has someone else seen this issue and found a workaround? Is it possible to disable interrupting the transition? Filed a feedback on the issue FB19601591 Screen recording: https://share.icloud.com/photos/04cio3fEcbR6u64PAgxuS2CLQ Example code @State var showDetail = false @Namespace var namespace var body: some View { NavigationStack { ScrollView { showDetailButton } .navigationTitle("Title") .navigationBarTitleDisplayMode(.inline) .navigationDestination(isPresented: $showDetail) { Text("Detail") .navigationTransition(.zoom(sourceID: "zoom", in: namespace)) } } } var showDetailButton: some View { Button { showDetail = true } label: { Text("Show detail") .padding() .background(.green) .matchedTransitionSource(id: "zoom", in: namespace) } } }

Programatic scroll edge effect for NSScrollView
Just like NSScrollView lets us programmatically set the contentInset in parallel to automaticallyAdjustsContentInsets, I think there should be similar functionality for blurring effect caused by scroll edge effect. I should be able programmatically set it. If the user is manually setting the contentInset then they can simply set a boolean, which when enabled will show edge effect when the scroll document goes outside the area of inset. Eg: scrollView.contentInsets = NSEdgeInsets(top: 100, left: 0, bottom: 0, right: 0) For contentInset like above set by user, they could set edge effect in two ways Automatically: scrollView.enableEdgeEffectOutsideInsets = true // This will apply edge effect based on frame size of contentInsets Programmatically: scrollView.edgeInsetEffectFrame = NSRect...

Is there a better way to hide a view in a custom Layout other than placing it off-screen?
I have a custom Layout that places a number of labels for a cell footer in a certain way based on the available width that needs to conditionally hide those views that do not entirely fit anymore (based on some priorities I specify). Currently I simply move the subviews that do not fit anymore off-screen and use clipping to hide them outside the layout, as I did not find an "official" way to hide / exclude a subview from a Layout. Does anyone know a better / nicer way to do this in SwiftUI?

Pass data to an @Observable model
Overview I have a navigation split view. The detail view contains a model now this model depends on id from the parent view. Questions How can I pass data from the parent view and yet create the view in the detail view? Or should I be pass the model from the parent view, but the problem is the parent view needs to persist model. Or is there a better approach?

AsyncRenderer stack limit
We've been getting stack overflows in code we don't control, in the background AsyncRenderer thread in a chain of calls to updateInheritedViewAsync. But the stack is less than 200 calls deep, presumably because it's a background thread with a smaller stack limit. Is it possible to adjust AsyncRenderer's stack limit? Or otherwise, what limits should we be aware of to prevent running into this issue? com.apple.SwiftUI.AsyncRenderer: EXC_BAD_ACCESS (code=2, address=0x16f5ebe30) #0 0x000000019c6b4460 in function signature specialization <Arg[3] = Dead> of static SwiftUI.DisplayList.ViewUpdater.Model.merge(item: inout SwiftUI.DisplayList.Item, index: SwiftUI.DisplayList.Index, into: inout SwiftUI.DisplayList.ViewUpdater.Model.State) -> SwiftUI.DisplayList.ViewUpdater.Model.MergedViewRequirements () #1 0x000000019c7c2850 in SwiftUI.DisplayList.ViewUpdater.updateInheritedViewAsync(platform: SwiftUI.DisplayList.ViewUpdater.Platform, oldItem: SwiftUI.DisplayList.Item, oldParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>, newItem: SwiftUI.DisplayList.Item, newParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>) -> Swift.Optional<SwiftUI.Time> () #2 0x000000019c7c3ef0 in SwiftUI.DisplayList.ViewUpdater.updateInheritedViewAsync(platform: SwiftUI.DisplayList.ViewUpdater.Platform, oldItem: SwiftUI.DisplayList.Item, oldParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>, newItem: SwiftUI.DisplayList.Item, newParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>) -> Swift.Optional<SwiftUI.Time> () #3 0x000000019c7c3ef0 in SwiftUI.DisplayList.ViewUpdater.updateInheritedViewAsync(platform: SwiftUI.DisplayList.ViewUpdater.Platform, oldItem: SwiftUI.DisplayList.Item, oldParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>, newItem: SwiftUI.DisplayList.Item, newParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>) -> Swift.Optional<SwiftUI.Time> () #4 0x000000019c7c3ef0 in SwiftUI.DisplayList.ViewUpdater.updateInheritedViewAsync(platform: SwiftUI.DisplayList.ViewUpdater.Platform, oldItem: SwiftUI.DisplayList.Item, oldParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>, newItem: SwiftUI.DisplayList.Item, newParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>) -> Swift.Optional<SwiftUI.Time> () ... #147 0x000000019c7c364c in SwiftUI.DisplayList.ViewUpdater.updateInheritedViewAsync(platform: SwiftUI.DisplayList.ViewUpdater.Platform, oldItem: SwiftUI.DisplayList.Item, oldParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>, newItem: SwiftUI.DisplayList.Item, newParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>) -> Swift.Optional<SwiftUI.Time> () #148 0x000000019c7c2074 in SwiftUI.DisplayList.ViewUpdater.updateAsync(platform: SwiftUI.DisplayList.ViewUpdater.Platform, oldList: SwiftUI.DisplayList, oldParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>, newList: SwiftUI.DisplayList, newParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>) -> Swift.Optional<SwiftUI.Time> () #149 0x000000019c7c1a78 in renderAsync () #150 0x000000019c60fc68 in renderDisplayList () #151 0x000000019c612094 in protocol witness for SwiftUI.ViewGraphRenderHost.renderDisplayList(_: SwiftUI.DisplayList, asynchronously: Swift.Bool, time: SwiftUI.Time, nextTime: SwiftUI.Time, targetTimestamp: Swift.Optional<SwiftUI.Time>, version: SwiftUI.DisplayList.Version, maxVersion: SwiftUI.DisplayList.Version) -> SwiftUI.Time in conformance SwiftUI.ViewGraph : SwiftUI.ViewGraphRenderHost in SwiftUI () #152 0x000000019c7c0dd0 in renderAsync () #153 0x000000019c7be6c8 in SwiftUI.ViewGraphHost.displayLinkTimer(timestamp: SwiftUI.Time, targetTimestamp: SwiftUI.Time, isAsyncThread: Swift.Bool) -> () () #154 0x000000019c7beab8 in SwiftUI.ViewGraphDisplayLink.displayLinkTimer(__C.CADisplayLink) -> () () #155 0x000000019c7be5a8 in @objc SwiftUI.ViewGraphDisplayLink.displayLinkTimer(__C.CADisplayLink) -> () () #156 0x0000000192fdbb24 in CA::Display::DisplayLinkItem::dispatch_ () #157 0x0000000192fb9164 in CA::Display::DisplayLink::dispatch_items () #158 0x0000000192f91870 in display_timer_callback () #159 0x000000019256d4cc in __CFMachPortPerform () #160 0x000000019259d0b0 in __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION__ () #161 0x000000019259cfd8 in __CFRunLoopDoSource1 () #162 0x0000000192574c1c in __CFRunLoopRun () #163 0x0000000192573a6c in _CFRunLoopRunSpecificWithOptions () #164 0x0000000190533f54 in -[NSRunLoop(NSRunLoop) runMode:beforeDate:] () #165 0x000000018fb9a51c in -[NSRunLoop(NSRunLoop) run] () #166 0x000000019c7cd5b0 in function signature specialization <Arg[1] = Dead> of static SwiftUI.ViewGraphDisplayLink.asyncThread(arg: Swift.Optional<Any>) -> () () #167 0x000000019c7cd288 in @objc static SwiftUI.ViewGraphDisplayLink.asyncThread(arg: Swift.Optional<Any>) -> () () #168 0x000000018fbf321c in __NSThread__start__ () #169 0x00000001ef0d044c in _pthread_start ()

How to obtain an app icon regardless of current icon style?
Hey Team, Using NSWorkspace.icon(forFile:) and pointing to an app bundle, the system returns an NSImage with the icon of the app, but in the current style. For example, if the user selected tinted icons in Appearance in System Settings, then any icon I receive back from the API will be tinted using the current accent color. Is there a way to override this and get the original icon? Thanks, Ari

Making View's init nonisolated with environment variables
Views with custom nonisolated init fail to compile when using @MainActor-isolated @Environment properties (e.g., \.openURL, \.dismiss). From the Swift 6 migration documentation, it seems encouraged to define inits nonisolated, and it seems base SwiftUI components also have their inits defined as nonisolated (e.g. TimelineView, LazyHStack, etc), which makes sense. How do you achieve marking a SwiftUI View's init as nonisolated when it uses environment variables, without producing the following build error "Main actor-isolated default value of 'self.openURL' cannot be used in a nonisolated initalizer" ? It seems @State variable defined in a view has the ability to be set in a nonisolated init but not @Environment. What mechanism prevents this under the hood ?

How to get the glassy picker showed at WWD27
In the session "What’s new in SwiftUI", at 02:38 Steven shows various Liquid Glass components, among them, a very pretty interactive glassy Picker. At first I thought this was built into the system and tried everything possible, until to rewatch the presentation and notice this: "On macOS, like on iOS, you can mark Liquid Glass custom elements as "interactive" so they respond more fluidly to user's clicks. And this is optimized to work great with the mouse pointer, so it feels right at home on the Mac." Does anyone have pointers to where one can find a Picker that implements all these system behaviors that folks have come to expect? I have my own version, which is deeply lacking, and so is every other implementation out there that I saw, and I thought sprinkling some "interactive" as instructed would help, but it barely made a dent.

Best practice for activating a menubar app
Hey Team, I'm developing an app that normally resides in the menu bar and has no Dock icon (activation policy set to accessory. When the user clicks the status icon, and selects 'Settings' in the menu, I change the activation policy to regular, show the window, and activate the app. Since cooperative activation was introduced, the option to ignore all apps when activating was deprecated, so I activate the app without the option. The result is that in 20% of the times, the window doesn't come to the front, or the app is not activated. The user obviously wants this behavior, so what is the proper way to achieve it? Thanks, Ari

Handling View Creation for Heterogeneous Data
In my project (an Package), I have created an Manager (can be classified as an ViewModel) that will handle state updates throughout the Package Component view: Note: The code is simplified for better understanding and to focus on principles behind things I did. The manager does complex things during state updates. public class ComponentManager: ObservedObject { @Published var rows: [any RowProtocol] = [] func updateState(_ newState: any RowProtocolData, id: String) { guard let index = rows.firstIndex(where: { $0.id == id }) else { return } rows[index].updateState(newState) } func getState(id: String) -> any RowProtocolData? { guard let index = rows.firstIndex(where: { $0.id == id }) else { return nil } return rows[index].state } } The RowProtocol is defined as follows: public protocol RowStateProtocol {} public protocol RowProtocol: Identifiable { associatedtype State: RowStateProtocol associatedtype RowView: View var id: String { get } var state: State { get } func updateState(_ newState: State) @MainActor @ViewBuilder func renderRow() -> RowView } extension RowProtocol { func updateState(_ newState: any RowProtocolData) { guard let newState = newState as? State else { return } self.updateState(newState) } } Then in Component View, I need to render the rows based on the underlying type of the row, this where the renderRow() comes in: struct ComponentView: View { @ObservedObject var manager: ComponentManager var body: some View { List { ForEach(manager.rows, id: \.id) { row in HStack { // This HStack prevent List from initing all rows due to AnyView. AnyView(row.renderRow()) } } } } } The row views will be accepting binding to the state of the row and update their state, let says we have a TextRow and a ToggleRow: struct TextRow: RowProtocol { var id: String var state: TextRowState func updateState(_ newState: TextRowState) { self.state = newState } } struct ToggleRow: RowProtocol { var id: String var state: ToggleRowState func updateState(_ newState: ToggleRowState) { self.state = newState } } In this, offcourse we cannot create an binding directly to the state of the row, since the state are through the manager and the row data won't have access to the manager. So I created an property wrapped that use the closures passed by the manager into environment to create the binding and an view that will give the binding to the content view: extenstion EnvironmentValues { @Entry internal var getState: (String) -> any RowStateProtocol? @Entry internal var updateState: (any RowStateProtocol, String) -> Void } @propertyWrapper struct RowStateBinding<State: RowStateProtocol & Equatable>: DynamicProperty { @Environment(\.getState) private var getState @Environment(\.updateState) private var updateState private let id: String init(id: String) { self.id = id } var wrappedValue: State { get { getState(id) as! State } nonmutating set { if wrappedValue != newValue { // only update for an new change, since set can be triggered for any number of reasons. updateState(newValue, id) } } } var projectedValue: Binding<State> { Binding( get: { self.wrappedValue }, set: { newValue in self.wrappedValue = newValue } ) } } struct RowStateBindingView<Content: View, State: RowStateProtocol & Equatable>: View { @RowStateBinding<State> private var state: State private let content: (Binding<State>) -> Content init(id: String, @ViewBuilder content: @escaping (Binding<State>) -> Content) { self._state = RowStateBinding(id: id) self.content = content } var body: some View { content($state) } } and in the renderRows: struct TextRowView: View { @Binding var text: TextRowState var body: some View { TextField("Enter text", text: $text.text) } } extension TextRow { func renderRow() -> some View { RowStateBindingView(id: id) { state in TextField("Enter text", text: state.text) } } } struct ToggleRowView: View { @Binding var state: ToggleRowState var body: some View { Toggle("Toggle", isOn: $state.isOn) } } extension ToggleRow { func renderRow() -> some View { RowStateBindingView(id: id) { state in Toggle("Toggle", isOn: state.isOn) } } } This way, I can adopt any view as an row view and most importantly, the view can be completely independent of the manager and used as an standalone view. Also clients of the library can create their own custom rows by just conforming to the RowProtocol and creating the view for it, without worrying about how the state management works. The manager will handle all the state updates. I prefer using stucts over classes for rows and states, since its easier to manage state updates. What do you think about this approach? Do you see any potential issues with this? Is there a better way to achieve this?

Crash occured in UIDatePicker Calendar type
I am encountering a consistent, reproducible crash in our app when presenting a UIDatePicker configured with the calendar style. The crash triggers every single time the picker is invoked and points directly to the modern date picker's internal UICollectionView. The Exception: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UICollectionView internal inconsistency: attempted to set layout with the collection view requiring a reload' let datePicker = UIDatePicker() datePicker.datePickerMode = .date datePicker.preferredDatePickerStyle = .compact This crash is occuring in inline style too when I try to open the calendar. I tried this in other apps. It works fine. I didn't override any collectionView layouts

Summary of iOS/iPadOS 26 UIKit bugs related to UISearchController & UISearchBar using scope buttons
All of these issues appear when the search controller is set on the view controller's navigationItem and the search controller's searchBar has its scopeButtonTitles set. So far the following issues are affecting my app on iOS/iPadOS 26 as of beta 7: When the scopeBarActivation of UISearchController is set to .onSearchActivation, the preferredSearchBarPlacement of the navigationItem is set to .integratedButton, and the searchBarPlacementAllowsToolbarIntegration is set to false (forcing the search icon to appear in the nav bar), on both iPhones and iPads, the scope buttons never appear. They don't appear when the search is activated. They don't appear when any text is entered into the search bar. FB19771313 I attempted to work around that issue by setting the scopeBarActivation to .manual. I then show the scope bar in the didPresentSearchController delegate method and hide the scope bar in the willDismissSearchController. On an iPhone this works though the display is a bit clunky. On an iPad, the scope bar does appear via the code in didPresentSearchController, but when any scope bar button is tapped, the search controller is dismissed. This happens when the app is horizontally regular. When the app on the iPad is horizontally compact, the buttons work but the search bar's text is not correctly aligned within the search bar. Quite the mess really. I still need to post a bug report for this issue. But if issue 1 above is fixed then I don't need this workaround. When the scopeBarActivation of UISearchController is set to .onSearchActivation, the preferredSearchBarPlacement of the navigationItem is set to .stacked, and the hidesSearchBarWhenScrolling property of the navigationItem is set to false (always show the search bar), and this is all used in a UITableViewController, then upon initial display of the view controller on an iPhone or iPad, you are unable to tap on the first row of the table view except on the very bottom of the row. The currently hidden scope bar is stealing the touches. If you activate and then cancel the search (making the scope bar appear and then disappear) then you are able to tap on the first row as expected. The initially hidden scope bar also bleeds through the first row of the table. It's faint but you can tell it's not quite right. Again, this is resolved by activating and then canceling the search once. FB17888632 When the scopeBarActivation of UISearchController is set to .onSearchActivation, the preferredSearchBarPlacement of the navigationItem is set to integrated or .integratedButton, and the toolbar is shown, then on iPhones (where the search bar/icon appears in the toolbar) the scope buttons appear (at the top of the screen) the first time the search is activated. But if you cancel the search and then activate it again, the search bar never appears a second (or later) time. On an iPad the search bar/icon appears in the nav bar and you end up with the same issue as #1 above. FB17890125 Issues 3 and 4 were reported against beta 1 and still haven't been fixed. But if issue 1 is resolved on iPhone, iPad, and Mac (via Mac Catalyst), then I personally won't be affected by issues 2, 3, or 4 any more (but of course all 4 issues need to be fixed). And by resolved, I mean that the scope bar appears and disappears when it is supposed to each and every time the search is activated and cancelled (not just the first time). The scope bar doesn't interfere with touch events upon initial display of the view controller. And there are no visual glitches no matter what the horizontal size class is on an iPad. I really hope the UIKit team can get these resolved before iOS/iPadOS 26 GM.

UIView wrapper around a View
I couldn't decide whether to post this question here or in SwiftUI Q&A as there's a lot of overlaps. We're trying to create something similar to UIViewRepresentable for UIKit. This might not work for complicated cases where the View has many pieces but as long as it works for simple cases, we're happy. The only problem right now is figuring out the correct height. Currently, the height anchor is assigned to CGFloat.greatestFiniteMagnitude, which works but when inspecting the layout in View Hierarchy, it appears the wrapped view is getting stretched all the way down. Also, sometimes View Hierarchy isn't able to draw the wrapped View and I'm unsure if it's a problem of View Hierarchy or our implementation. final public class SwiftUIConfigurationContainerView<T: View>: UIView { private var contentView: UIView? public override var intrinsicContentSize: CGSize { contentView?.intrinsicContentSize ?? super.intrinsicContentSize } private var preferredContentSize: CGSize? public init(@ViewBuilder _ content: @escaping () -> T) { super.init(frame: .zero) setUpContentView(content) } @available(*, unavailable) required init?(coder: NSCoder) { return nil } private func setUpContentView(_ content: @escaping () -> T) { let contentView = UIHostingConfiguration { [weak self] in VStack(spacing: .zero) { content() .onGeometryChange(for: CGSize.self, of: \.size) { size in self?.preferredContentSize = size self?.invalidateIntrinsicContentSize() } .frame(maxWidth: .infinity, alignment: .center) Spacer(minLength: .zero) } } .minSize(width: .zero, height: .zero) .margins(.all, .zero) .makeContentView() self.contentView = contentView addSubview(contentView) contentView.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ contentView.leadingAnchor.constraint(equalTo: leadingAnchor), contentView.trailingAnchor.constraint(equalTo: trailingAnchor), contentView.topAnchor.constraint(equalTo: topAnchor), contentView.heightAnchor.constraint(equalToConstant: CGFloat.greatestFiniteMagnitude), ]) } }

SwiftUI ​Charts: In iOS 27, annotation overlays exceed the bounds of an annotation
I'm seeing a regression in SwiftUI Charts on iOS 27 beta 1. Any view placed inside a BarMark's overlay annotation no longer receives the size of the parent BarMark. It collapses to zero, so any content sized from geo.size (e.g. a Rectangle meant to fill the bar) renders empty or incorrectly. Expected: The GeometryReader reports the BarMark's rendered width/height, and the Rectangle fills the BarMark (this is the behavior in iOS 26 and earlier). Actual: On iOS 27 beta 1, geo.size is effectively zero, so the overlay content has an extremely small size. I suspect this could be a small bug with the new ContentBuilder / ViewBuilder changes but that's just a hunch. Here's a code sample which reproduces the issue. // MARK: - Mock Data Models struct ScheduleSeries: Identifiable { let id = UUID() let data: [ScheduleItem] } struct ScheduleItem: Identifiable { let id = UUID() let startDate: Date let startHour: Double let endHour: Double let secondaryText: String? } // MARK: - Minimal Reproducible Example struct ContentView: View { // Generate two consecutive days for the mock data let mockSchedule: [ScheduleSeries] = [ ScheduleSeries(data: [ ScheduleItem( startDate: Date(), startHour: 9.0, endHour: 11.5, secondaryText: "Morning Event" ), ScheduleItem( startDate: Calendar.current.date(byAdding: .day, value: 1, to: Date())!, startHour: 13.0, endHour: 16.0, secondaryText: "Afternoon Event" ) ]) ] var body: some View { VStack(alignment: .leading) { Text("FB: Annotation Sizing Bug") .font(.headline) .padding(.bottom, 8) Text("Expected: The gray Rectangle should stretch to fill the BarMark.\nActual: GeometryReader/Annotation fails to size to the parent BarMark.") .font(.caption) .foregroundColor(.secondary) .padding(.bottom) Chart(mockSchedule) { series in ForEach(series.data, id: \.startDate) { element in BarMark( x: .value("Day", element.startDate, unit: .day, calendar: .current), yStart: .value("Start", element.startHour), yEnd: .value("End", element.endHour), width: .ratio(0.99) ) .annotation(position: .overlay, alignment: .topLeading) { item in ZStack { VStack(alignment: .leading, spacing: 0) { // BUG DEMONSTRATION: // This GeometryReader and Rectangle previously filled the BarMark, but in Xcode 27 it does not GeometryReader { geo in Rectangle() .fill(Color.black.opacity(0.15)) .frame(width: geo.size.width, height: geo.size.height) } } .foregroundColor(.white) .font(.caption2) } } } } .chartYScale(domain: 0...24) // Lock the Y-axis to a 24-hour scale } .padding() } } Environment: Xcode 27 beta 1 / iOS 27 beta 1 Reproduces on device and Simulator Worked as expected on iOS 26 and earlier Here's what the issue looks like in our app with zero code changes: iOS 26 iOS 27 I've filed a feedback report (FB23016343) with a sample project attached. Has anyone else hit this, or found a workaround for sizing overlay annotation content to a BarMark in iOS 27? Thanks!

How to detect backspace in SwiftUI TextField without falling back to UIViewRepresentable?
I'm building a multi-box PIN/OTP input in SwiftUI. In UIKit, I used UITextFieldDelegate to detect backspace presses on an empty field to move focus backward. SwiftUI’s .onChange(of: text) only triggers when text is actually deleted, completely missing backspaces on an already empty field. Is there a pure SwiftUI way to handle this now, or are we still forced to wrap UITextField via UIViewRepresentable?

Source view disappearing when interrupting a zoom navigation transition
When I use the .zoom transition in a navigation stack, I get a glitch when interrupting the animation by swiping back before it completes. When doing this, the source view disappears. I can still tap it to trigger the navigation again, but its not visible on screen. This seems to be a regression in iOS 26, as it works as expected when testing on iOS 18. Has someone else seen this issue and found a workaround? Is it possible to disable interrupting the transition? Filed a feedback on the issue FB19601591 Screen recording: https://share.icloud.com/photos/04cio3fEcbR6u64PAgxuS2CLQ Example code @State var showDetail = false @Namespace var namespace var body: some View { NavigationStack { ScrollView { showDetailButton } .navigationTitle("Title") .navigationBarTitleDisplayMode(.inline) .navigationDestination(isPresented: $showDetail) { Text("Detail") .navigationTransition(.zoom(sourceID: "zoom", in: namespace)) } } } var showDetailButton: some View { Button { showDetail = true } label: { Text("Show detail") .padding() .background(.green) .matchedTransitionSource(id: "zoom", in: namespace) } } }

Programatic scroll edge effect for NSScrollView
Just like NSScrollView lets us programmatically set the contentInset in parallel to automaticallyAdjustsContentInsets, I think there should be similar functionality for blurring effect caused by scroll edge effect. I should be able programmatically set it. If the user is manually setting the contentInset then they can simply set a boolean, which when enabled will show edge effect when the scroll document goes outside the area of inset. Eg: scrollView.contentInsets = NSEdgeInsets(top: 100, left: 0, bottom: 0, right: 0) For contentInset like above set by user, they could set edge effect in two ways Automatically: scrollView.enableEdgeEffectOutsideInsets = true // This will apply edge effect based on frame size of contentInsets Programmatically: scrollView.edgeInsetEffectFrame = NSRect...

Is there a better way to hide a view in a custom Layout other than placing it off-screen?
I have a custom Layout that places a number of labels for a cell footer in a certain way based on the available width that needs to conditionally hide those views that do not entirely fit anymore (based on some priorities I specify). Currently I simply move the subviews that do not fit anymore off-screen and use clipping to hide them outside the layout, as I did not find an "official" way to hide / exclude a subview from a Layout. Does anyone know a better / nicer way to do this in SwiftUI?

Pass data to an @Observable model
Overview I have a navigation split view. The detail view contains a model now this model depends on id from the parent view. Questions How can I pass data from the parent view and yet create the view in the detail view? Or should I be pass the model from the parent view, but the problem is the parent view needs to persist model. Or is there a better approach?

AsyncRenderer stack limit
We've been getting stack overflows in code we don't control, in the background AsyncRenderer thread in a chain of calls to updateInheritedViewAsync. But the stack is less than 200 calls deep, presumably because it's a background thread with a smaller stack limit. Is it possible to adjust AsyncRenderer's stack limit? Or otherwise, what limits should we be aware of to prevent running into this issue? com.apple.SwiftUI.AsyncRenderer: EXC_BAD_ACCESS (code=2, address=0x16f5ebe30) #0 0x000000019c6b4460 in function signature specialization <Arg[3] = Dead> of static SwiftUI.DisplayList.ViewUpdater.Model.merge(item: inout SwiftUI.DisplayList.Item, index: SwiftUI.DisplayList.Index, into: inout SwiftUI.DisplayList.ViewUpdater.Model.State) -> SwiftUI.DisplayList.ViewUpdater.Model.MergedViewRequirements () #1 0x000000019c7c2850 in SwiftUI.DisplayList.ViewUpdater.updateInheritedViewAsync(platform: SwiftUI.DisplayList.ViewUpdater.Platform, oldItem: SwiftUI.DisplayList.Item, oldParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>, newItem: SwiftUI.DisplayList.Item, newParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>) -> Swift.Optional<SwiftUI.Time> () #2 0x000000019c7c3ef0 in SwiftUI.DisplayList.ViewUpdater.updateInheritedViewAsync(platform: SwiftUI.DisplayList.ViewUpdater.Platform, oldItem: SwiftUI.DisplayList.Item, oldParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>, newItem: SwiftUI.DisplayList.Item, newParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>) -> Swift.Optional<SwiftUI.Time> () #3 0x000000019c7c3ef0 in SwiftUI.DisplayList.ViewUpdater.updateInheritedViewAsync(platform: SwiftUI.DisplayList.ViewUpdater.Platform, oldItem: SwiftUI.DisplayList.Item, oldParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>, newItem: SwiftUI.DisplayList.Item, newParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>) -> Swift.Optional<SwiftUI.Time> () #4 0x000000019c7c3ef0 in SwiftUI.DisplayList.ViewUpdater.updateInheritedViewAsync(platform: SwiftUI.DisplayList.ViewUpdater.Platform, oldItem: SwiftUI.DisplayList.Item, oldParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>, newItem: SwiftUI.DisplayList.Item, newParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>) -> Swift.Optional<SwiftUI.Time> () ... #147 0x000000019c7c364c in SwiftUI.DisplayList.ViewUpdater.updateInheritedViewAsync(platform: SwiftUI.DisplayList.ViewUpdater.Platform, oldItem: SwiftUI.DisplayList.Item, oldParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>, newItem: SwiftUI.DisplayList.Item, newParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>) -> Swift.Optional<SwiftUI.Time> () #148 0x000000019c7c2074 in SwiftUI.DisplayList.ViewUpdater.updateAsync(platform: SwiftUI.DisplayList.ViewUpdater.Platform, oldList: SwiftUI.DisplayList, oldParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>, newList: SwiftUI.DisplayList, newParentState: Swift.UnsafePointer<SwiftUI.DisplayList.ViewUpdater.Model.State>) -> Swift.Optional<SwiftUI.Time> () #149 0x000000019c7c1a78 in renderAsync () #150 0x000000019c60fc68 in renderDisplayList () #151 0x000000019c612094 in protocol witness for SwiftUI.ViewGraphRenderHost.renderDisplayList(_: SwiftUI.DisplayList, asynchronously: Swift.Bool, time: SwiftUI.Time, nextTime: SwiftUI.Time, targetTimestamp: Swift.Optional<SwiftUI.Time>, version: SwiftUI.DisplayList.Version, maxVersion: SwiftUI.DisplayList.Version) -> SwiftUI.Time in conformance SwiftUI.ViewGraph : SwiftUI.ViewGraphRenderHost in SwiftUI () #152 0x000000019c7c0dd0 in renderAsync () #153 0x000000019c7be6c8 in SwiftUI.ViewGraphHost.displayLinkTimer(timestamp: SwiftUI.Time, targetTimestamp: SwiftUI.Time, isAsyncThread: Swift.Bool) -> () () #154 0x000000019c7beab8 in SwiftUI.ViewGraphDisplayLink.displayLinkTimer(__C.CADisplayLink) -> () () #155 0x000000019c7be5a8 in @objc SwiftUI.ViewGraphDisplayLink.displayLinkTimer(__C.CADisplayLink) -> () () #156 0x0000000192fdbb24 in CA::Display::DisplayLinkItem::dispatch_ () #157 0x0000000192fb9164 in CA::Display::DisplayLink::dispatch_items () #158 0x0000000192f91870 in display_timer_callback () #159 0x000000019256d4cc in __CFMachPortPerform () #160 0x000000019259d0b0 in __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION__ () #161 0x000000019259cfd8 in __CFRunLoopDoSource1 () #162 0x0000000192574c1c in __CFRunLoopRun () #163 0x0000000192573a6c in _CFRunLoopRunSpecificWithOptions () #164 0x0000000190533f54 in -[NSRunLoop(NSRunLoop) runMode:beforeDate:] () #165 0x000000018fb9a51c in -[NSRunLoop(NSRunLoop) run] () #166 0x000000019c7cd5b0 in function signature specialization <Arg[1] = Dead> of static SwiftUI.ViewGraphDisplayLink.asyncThread(arg: Swift.Optional<Any>) -> () () #167 0x000000019c7cd288 in @objc static SwiftUI.ViewGraphDisplayLink.asyncThread(arg: Swift.Optional<Any>) -> () () #168 0x000000018fbf321c in __NSThread__start__ () #169 0x00000001ef0d044c in _pthread_start ()

How to obtain an app icon regardless of current icon style?
Hey Team, Using NSWorkspace.icon(forFile:) and pointing to an app bundle, the system returns an NSImage with the icon of the app, but in the current style. For example, if the user selected tinted icons in Appearance in System Settings, then any icon I receive back from the API will be tinted using the current accent color. Is there a way to override this and get the original icon? Thanks, Ari

Making View's init nonisolated with environment variables
Views with custom nonisolated init fail to compile when using @MainActor-isolated @Environment properties (e.g., \.openURL, \.dismiss). From the Swift 6 migration documentation, it seems encouraged to define inits nonisolated, and it seems base SwiftUI components also have their inits defined as nonisolated (e.g. TimelineView, LazyHStack, etc), which makes sense. How do you achieve marking a SwiftUI View's init as nonisolated when it uses environment variables, without producing the following build error "Main actor-isolated default value of 'self.openURL' cannot be used in a nonisolated initalizer" ? It seems @State variable defined in a view has the ability to be set in a nonisolated init but not @Environment. What mechanism prevents this under the hood ?

How to get the glassy picker showed at WWD27
In the session "What’s new in SwiftUI", at 02:38 Steven shows various Liquid Glass components, among them, a very pretty interactive glassy Picker. At first I thought this was built into the system and tried everything possible, until to rewatch the presentation and notice this: "On macOS, like on iOS, you can mark Liquid Glass custom elements as "interactive" so they respond more fluidly to user's clicks. And this is optimized to work great with the mouse pointer, so it feels right at home on the Mac." Does anyone have pointers to where one can find a Picker that implements all these system behaviors that folks have come to expect? I have my own version, which is deeply lacking, and so is every other implementation out there that I saw, and I thought sprinkling some "interactive" as instructed would help, but it barely made a dent.

Best practice for activating a menubar app
Hey Team, I'm developing an app that normally resides in the menu bar and has no Dock icon (activation policy set to accessory. When the user clicks the status icon, and selects 'Settings' in the menu, I change the activation policy to regular, show the window, and activate the app. Since cooperative activation was introduced, the option to ignore all apps when activating was deprecated, so I activate the app without the option. The result is that in 20% of the times, the window doesn't come to the front, or the app is not activated. The user obviously wants this behavior, so what is the proper way to achieve it? Thanks, Ari
