My SwiftUI app uses an Image with a tap gesture:
Image(systemName: "xmark.circle.fill")
.accessibilityIdentifier(kTextFieldClearButton)
.foregroundColor(.secondary)
.padding(.trailing, 6)
.onTapGesture {
dataSource.textFieldText = ""
}
In a UI test, I want to tap this image to execute its action:
let clearButton = app.images[kTextFieldClearButton]
clearButton.tap()
However the action is not executed.
I then set a breakpoint at clearButton.tap(), to execute lldb commands. Here are the results:
(lldb) p clearButton.isHittable
t = 439.54s Find the "TextFieldClearButton" Imag
(Bool) true
e
It is a little strange that "Image" has been interrupted by (Bool) true, but the image is hittable.
p clearButton.isAccessibilityElement
gives
(lldb) p clearButton.isAccessibilityElement
(Bool) false
I don't understand why this Image is no accessibility element. I thought, SwiftUI Views are by default accessible.
What can I do to make it accessible so that clearButton.tap() works as expected?

I understand two key concepts from desktop platforms:
Screen Mirroring – The same content is displayed on both the primary and external screens.
Screen Extension – The external display shows different content that complements what's on the main screen.
My question pertains to the second point: Is it possible to extend the display on iOS and iPadOS devices?
I'm referring to this Apple documentation, which explains how to extend content from an iOS/iPadOS device to an external display.
I tested this in a sample iOS Xcode project. In the iOS Simulator, I was able to detect an "external display" and present a separate UIWindow on it. However, when I tried the same on a real device (iPhone 15 connected to a MacBook Pro via cable), the external display connection was not detected.
I’d like to confirm whether screen extension is possible on a real iOS device. From my research, it appears that extension is only supported on iPadOS via Stage Manager, but I want to verify if there’s any way to achieve this on an iPhone. If so, are there any known apps that currently utilize extended display functionality on iOS?
If extension is not possible on iOS, what does the documentation mentions iOS?
I've read all previous posts on this topic but none seem to address what I'm seeing for iOS 16 and using NavigationStack. I'm also using an overall @EnvironmentObject for navigation state.
I have a split view app. In the detail section, I have a NavigationStack surrounding the detail view. Within the detail view (MyView), there is a base view with a "+" button in the toolbar to create a new entity.
That opens NewEntityView where I show a grid of buttons for the user to select a type to create a new entity before moving to NewEntityView to fill in the details for the entity. The top row of the grid of buttons takes the user straight to the NewEntityView with a NavigationLink. These work fine.
The next row of buttons present a menu of sub-types and then should take the user to the NewEntityView view. These buttons do not work.
Code (simplified to not have clutter):
SplitViewDetailView:
struct SplitViewDetailView: View {
@EnvironmentObject var navigationManager: NavigationStateManager
@Binding var selectedCategory: Route?
var body: some View {
NavigationStack(path: $navigationManager.routes) {
// other irrelevant stuff
MyView()
}
.environmentObject(navigationManager)
.navigationDestination(for: Route.self) { $0 }
}
}
MyView:
struct MyView: View {
@EnvironmentObject var navigationManager: NavigationStateManager
var body: some View {
List {
// other stuff
}
.toolbar {
ToolbarItem(placement: .navigationBarTrailing) {
Button(action: {}, label: {
NavigationLink(value: Route.newTypeSelect) {
Image(systemName: "plus")
.frame(width: 44, height: 44)
}
} )
}
}
.navigationDestination(for: Route.self) { $0 }
}
SelectTypeView:
struct SelectTypeView: View {
var body: some View {
ZStack {
VStack {
// Top row with no subtypes
HStack {
ForEach (topRows, id: \.self) { type in
NavigationLink(value: Route.newEntityDetails(type.rawValue)) { <-- these work
Text(type)
}
}
}
HStack {
ForEach (middleRow, id: \.self) { type in
Menu {
ForEach (subtype[type], id: \.self) { sub in
NavigationLink(value: Route.newEntityDetails(sub.rawValue)) { <-- these go nowhere
Text(sub)
}
}
} label: {
Text(type)
}
}
}
}
}
}
}
NavigationStateManager:
class NavigationStateManager: ObservableObject {
@Published var routes = [Route]()
// other stuff
}
And Route:
enum Route: Identifiable {
var id: UUID { UUID() }
case newTypeSelect
case newEntityDetails(String)
}
extension Route: View {
var body: some View {
switch self {
case .newTypeSelect:
SelectTypeView()
case .newEntityDetails(let type):
NewEntityView(selectedType: type)
}
}
}
The menus show up fine but tapping on an item does nothing. I've attempted to wrap the menu in its own NavigationStack but that is rejected stating it is already in one defined by a parent view. I've tried making the links Buttons with destinations and those are also rejected.
What is the newest/best way to present a menu with NavigationLinks? One doesn't simply wrap the menu in a NavigationView if one is using a NavigationStack?
Hey everyone!
I’m encountering an issue while attempting to animate height changes of the content inside safeAreaInset(edge:alignment:spacing:content:).
When animating a reduction in the frame height, the container view (in my case, Map) also animates unexpectedly.
However, when animating an increase in the frame height, the animation works smoothly, and the Map view remains still.
How can I address this odd resizing behavior of the container?
Code:
struct MapView: View {
var body: some View {
Map()
.safeAreaInset(edge: .bottom) {
MapDetailView()
}
}
}
struct MapDetailView: View {
@State private var oldHeightOffset: CGFloat = 0
@State private var newHeightOffset: CGFloat = 0
@State private var containerHeight: CGFloat = 0
private var drag: some Gesture {
DragGesture(coordinateSpace: .global)
.onChanged { value in
withAnimation(.interactiveSpring) {
newHeightOffset = oldHeightOffset + value.translation.height
}
}
.onEnded { value in
switch newHeightOffset {
case containerHeight * 0.625...containerHeight:
withAnimation(.spring) {
newHeightOffset = containerHeight * 0.75
}
case containerHeight * 0.25..<containerHeight * 0.625:
withAnimation(.spring) {
newHeightOffset = containerHeight * 0.5
}
case 0..<containerHeight * 0.25:
withAnimation(.spring) {
newHeightOffset = 0
}
default:
break
}
oldHeightOffset = newHeightOffset
}
}
var body: some View {
NavigationStack {
Rectangle()
.fill(.clear)
.containerBackground(.ultraThinMaterial, for: .navigation)
}
.gesture(drag)
.containerRelativeFrame(.vertical) { length, _ in
length - newHeightOffset
}
.onGeometryChange(for: CGFloat.self) { geometryProxy in
let frame = geometryProxy.frame(in: .local)
return frame.height + newHeightOffset
} action: { containerHeight in
self.containerHeight = containerHeight
}
}
}

Hi,
I have an existing AppKit-based Mac app that I have been working on for a few years. For a new feature, I wanted to have the app opened by a different app, so I setup the URL scheme under CFBundleURLTypes in my Info.plist, and adopted this delegate callback:
- (void)application: (NSApplication *)application openURLs:(nonnull NSArray<NSURL *> *)urls
Now when I invoke the URL from the 2nd app, it opens my app correctly, BUT this delegate method isn't called. What's interesting is that if I make a totally new app with a URL scheme and adopt this delegate method, it gets called without a problem!
SO what about my original project could be responsible for this 'opensURLs' method to not be called? I've been searching for a solution for a couple of days without any luck. The macOS app's target has a Deployment Target of 10.15 and I'm running this on macOS12.0 with Xcode 13.
I have a swiftui view with Button(intent: ) and using UIHostingViewcontroller to use it in UIKit. The problem is that button not works in uikit but normal button(without intent works)
I am developing a watchOS app with a tab view, and inside one of the tabs, I have a 2x2 collection view layout. Each collection item contains a view that handles:
Tap Gesture (.onTapGesture) → Executes an action immediately.
Long Press Gesture (LongPressGesture) → Triggers an update when long press starts and again when it ends.
Drag Gesture (DragGesture) → Updates the position while dragging and resets values when the gesture ends.
Issue:
Most of the time, the gestures work correctly, but if another finger swipes on the screen while a long press is active, sometimes the onEnded event does not trigger, leaving the button in an active state.
Observations:
The onTapGesture executes normally without issues.
The LongPressGesture starts as expected, but if another finger interacts with the screen, the onEnded of the drag gesture does not always trigger.
This results in the button remaining visually or functionally "pressed" until another interaction occurs.
Has anyone encountered similar behavior in watchOS? How can I ensure that long press and drag gestures always complete even when another finger swipes on the screen?
Thanks in advance!
In my macOS app I have a SwiftUI list that starts like this:
List(selection: $selection) {
HStack {
Label("Staging", systemImage: "arrow.up.square")
Spacer()
WorkspaceStatusBadge(unstagedCount: model.statusCounts.unstaged,
stagedCount: model.statusCounts.staged)
}
(where WorkspaceStatusBadge is a custom view that just contains a Text)
I'm trying to set the accessibility ID of that first cell so I can find it in XCUITest. If I apply the accessibilityIdentifier() modifier to the HStack, it instead sets the ID of the two static text elements inside it, and the cell still has no ID.
I could find the cell based on the ID of the child staticText, but I have some other cases where this doesn't work as well.
If I use .accessibilityElement() on the HStack, then XCUI sees a cell containing a Group element with the ID. This might be workable, but it's certainly not ideal.
So how do I set the ID of the cell itself?
When integrating SwiftData for an already existing app that uses CoreData as data management, I encounter errors.
When building the ModelContainer for the first time, the following error appears:
Error: Persistent History (184) has to be truncated due to the following entities being removed (all Entities except for the 2 where I defined a SwiftData Model)
class SwiftDataManager: ObservableObject {
static let shared = SwiftDataManager()
private let persistenceManager = PersistenceManager.shared
private init(){}
lazy var modelContainer: ModelContainer = {
do {
let storeUrl = persistenceManager.storeURL()
let schema = Schema([
HistoryIncident.self,
HistoryEvent.self
])
let modelConfig = ModelConfiguration(url: storeUrl)
return try ModelContainer(for: schema, configurations: [modelConfig])
} catch {
fatalError("Could not create ModelContainer: \(error)")
}
}()
}
@Model public class HistoryIncident {
var missionNr: String?
@Relationship(deleteRule: .cascade) var events: [HistoryEvent]?
public init(){}
}
@Model class HistoryEvent {
var decs: String?
var timestamp: Date?
init(){}
}
As soon as I call the following function.
func addMockEventsToCurrentHistorie() {
var descriptor = FetchDescriptor<HistoryIncident>()
let key = self.hKey ?? ""
descriptor.predicate = #Predicate { mE in
key == mE.key
}
let historyIncident = try? SwiftDataManager.shared.modelContext.fetch(descriptor).first
guard var events = historyIncident?.events else {return}
events.append(contentsOf: createEvents())
}
I get the error:

I have an app that acts as an agent (no dock/app, just menu bar icon). When the icon is clicked, I show a popover with a small user interface.
This works great, however, there is an issue. When a certain app is in full-screen and then my menu bar icon is clicked, the user interface shows just fine, until the mouse is moved outside the menu bar - then the user interface stays but the menu bar dismisses and closes.
Is there a way to keep the menu bar open, like when clicking on Control Center, in full-screen apps?
This is how I open my popover:
if let button = statusItem.button {
if popover.isShown {
self.popover.performClose(sender)
} else {
popover.show(relativeTo: button.bounds, of: button, preferredEdge: .minY)
popover.contentViewController?.view.window?.makeKey()
}
}
}
We were using below delegate methods from QuickLook to get modified PDF file URL after the sketching But we are not able see the multi line text properly laid out on PDF and part of text missing. Same time Other pencil kit tools are working as expected.
`func previewController(_ controller: QLPreviewController, didSaveEditedCopyOf previewItem: QLPreviewItem, at modifiedContentsURL: URL)
func previewController(_ controller: QLPreviewController, didUpdateContentsOf previewItem: any QLPreviewItem)`
We tested all code in iOS 18.2.
Please let us know if the text edited URL on PDF can be retrieved in any possible way without tampering text

Seems like a bug, has anyone else encountered this or found a way around it?
let home = homeViewController()
let rootNav = UINavigationController(rootViewController: home)
window?.rootViewController = rootNav
window?.makeKeyAndVisible()
let second = SecondViewController()
home.navigationController?.pushViewController(second, animated: false)
let third = ThirdViewController()
home.navigationController?.pushViewController(third, animated: false)
After the above is executed, the viewdidload and other related lifecycle methods in the SecondViewController are not executed。
Except for iOS18, other versions don't have this problem, so it's not a bug in iOS18, or iOS18 has optimized UINavigationController

Hi,
I thought that drag drop reorder should be very easy with SwiftUI, but apparently I was wrong (unless I'm missing something). It seems to me that SwiftUI's drag-drop reorder is only easy for List, which supports .onMove modifier.
However, for UI like Grid, a horizontal ScrollView with items in a HStack, I don't see any easy approach to implement this. For example,
ScrollView(.horizontal) {
HStack {
ForEach(items) {
ItemView(item)
}
}
}
Does anyone know what's the best way to implement drag drop reorder for this horizontal scroll view?
In my collection view I have allowsSelection, allowsSelectionDuringEditing, and allowsMultipleSelectionDuringEditing set to true.
In my delegate's collectionView(_:shouldBeginMultipleSelectionInteractionAt:) I return true unconditionally, getting me the desired behavior of triggering edit mode with a two-finger swipe. So far so good.
The problem is that collectionView(_:shouldBeginMultipleSelectionInteractionAt:) is also called on a single-finger click from a trackpad. Tapping one of my cells is supposed to open a sub-screen, so with this happening there's no way to navigate my screen using a trackpad. This also goes against the documentation, which says this delegate method is supposed to get called because of a two-finger swipe.
Is there a way to keep that call from happing from a trackpad click? Or a way to distinguish whether I'm getting the call because of an actual two finger swipe?
I’m building a SwiftUI app where the struct AppGroup is identified by a UUID and stored in a dictionary. My Task model has appGroupId: UUID?. In TaskDetailView, I create a custom Binding<AppGroup> from the store, then navigate to AppGroupDetailView. However, when I tap the NavigationLink, the console spams logs, CPU hits 100%, and it never stabilizes.
Relevant Code
AppGroupStore (simplified)
class AppGroupStore: ObservableObject {
@Published var appGroupsDict: [UUID: AppGroup] = [:]
func updateAppGroup(_ id: UUID, appGroup: AppGroup) {
appGroupsDict[id] = appGroup
}
// Returns a binding so views can directly read/write the AppGroup by id
func getBinding(withId id: UUID?) -> Binding<AppGroup> {
Binding(
get: {
if let id = id {
return self.appGroupsDict[id] ?? .empty
}
return .empty
},
set: { newValue in
print("New value set for \(newValue.name)")
self.updateAppGroup(newValue.id, appGroup: newValue)
}
)
}
// ...
}
AppGroup is a simple struct:
struct AppGroup: Identifiable, Codable {
let id: UUID
var name: String
var apps: [String]
static let empty = AppGroup(id: UUID(), name: "Empty", apps: [])
}
TaskDetailView (main part)
struct TaskDetailView: View {
@Binding var task: ToDoTask // has task.appGroupId: UUID?
@EnvironmentObject var appGroupStore: AppGroupStore
var body: some View {
let appGroup = appGroupStore.getBinding(withId: task.appGroupId)
print("Task load") // prints infinitely, CPU 100%
return List {
// ...
NavigationLink(destination: AppGroupDetailView(appGroup: appGroup)) {
Text(appGroup.wrappedValue.name)
}
}
.navigationTitle(task.name)
}
}
AppGroupDetailView (simplified)
struct AppGroupDetailView: View {
@Binding var appGroup: AppGroup
// ...
var body: some View {
List {
ForEach(appGroup.apps, id: \.self) { app in
Text(app)
}
}
.navigationTitle(appGroup.name)
}
}
Symptoms:
Tapping the NavigationLink leads to infinite “Task load” logs and 100% CPU usage.
The set closure (“New value set for...”) is never called, so it’s not repeatedly writing.
If I replace the Binding<AppGroup> with a read-only approach (just accessing the dictionary), it does not get stuck.
Question:
What might cause SwiftUI to keep re-rendering the body indefinitely, even if my custom get closure doesn’t explicitly mutate the state? Are there known pitfalls when using a dictionary-based store and returning a Binding like this?
Any help is much appreciated!
Thanks in advance for your insights!
I'm using UIDocumentBrowserViewController. This view controller automatically creates a TabView with navigation titles and up to two trailing navigation bar items.
To visualize this, open the Files app by Apple on an iPhone.
I want to do the following:
Add a third button and place it farthest on the trailing side.
Keep all three buttons blue (the default color), but adjust the color of the navigation title to use the primary text color (it is also currently blue, by default)
Button Order
If my button is represented by C, then the order from left-to-right or leading-to-trailing should be A B C.
I tried to add it by using additionaltrailingnavigationbarbuttonitems:
class DocumentBrowserViewController: UIDocumentBrowserViewController, UIDocumentBrowserViewControllerDelegate
{
override func viewDidLoad()
{
super.viewDidLoad()
let button = UIBarButtonItem(...)
additionalTrailingNavigationBarButtonItems.append(button)
}
}
This always adds it as the leftmost trailing item. The order when the view loads is C A B, where C represents my button.
Here are some things I've tried:
Add it in viewWillAppear - same results.
Add it in viewDidAppear - same results.
Add it using rightBarButtonItems - does not show up at all.
insert it at: 0 instead of appending it - same results.
Add it with a delay using DispatchQueue.main.async - same results.
After some experimentation, I realized that the arrays referenced by additionalTrailingNavigationBarButtons and rightBarButtonItems seem to be empty, other than my own button. This is the case even if the DispatchQueue delay is so long that the view has already rendered and the two default buttons are clearly visible. So I'm not sure how to place my button relative to these, since I can't figure out where they actually are in the view controller's properties.
How do I put my button farther to the trailing/right side of these two default buttons?
Title Color
The navigation titles created by UIDocumentBrowserViewController are blue when not in their inline format. I want them to use the primary text color instead.
In viewDidLoad, I could do something like this:
UINavigationBar.appearance().tintColor = UIColor.label
This will change the title color to white or black, but it will also change the color of the buttons. I've tried various approaches like titleTextAttributes, and none of them seem to work with this view controller.
How do I change just the color of the navigation title, and not the color of the navigation bar items?

I'm encountering an issue displaying a large HTML string (over 11470 characters) in a UILabel. Specifically, the Arabic text within the string is rendering left-to-right instead of the correct right-to-left direction. I've provided a truncated version of the HTML string and the relevant code snippet below. I've tried setting the UILabel's text alignment to right, but this didn't resolve the issue. Could you please advise on how to resolve this bidirectional text rendering problem?
The results of the correct and incorrect approaches are shown in the image below.
Here's the relevant Swift code:
let labelView: UILabel = {
let label = UILabel()
label.textAlignment = .right
label.translatesAutoresizingMaskIntoConstraints = false
label.numberOfLines = 0
label.semanticContentAttribute = .forceRightToLeft
label.backgroundColor = .white
label.lineBreakMode = .byWordWrapping
return label
}()
//Important!!
//It must exceed 11470 characters.
let htmlString = """

if let data = htmlString.data(using: .utf8) {
let options: [NSAttributedString.DocumentReadingOptionKey: Any] = [

do {
let attributedString = try NSAttributedString(data: data, options: options, documentAttributes: nil)
labelView.attributedText = attributedString
} catch {
print("HTML string işlenirken hata oluştu: \(error)")
}
}
I'm using iOS 18.2 and Swift 6. Any suggestions on how to correct the bidirectional text rendering?
I'm working on a SwiftUI based application for MacOS. I have a TabView component with two child Tab components. These Tab components display a List, each derived from an array of elements.
While the application is running, clicking on the tabs in the TabView should switch between the views of different Lists. What I'm experiencing is that switching between the tabs causes a FAULT. With errors:
Row index 1 out of row range (numberOfRows: 1) for <SwiftUI.SwiftUIOutlineListView: 0x1299d2000>
Followed by:

)
And finally:
FAULT: NSTableViewException: Row index 1 out of row range (numberOfRows: 1) for <SwiftUI.SwiftUIOutlineListView: 0x1299d2000>; (user info absent)
This error happens when switching between the two tabs, defined thusly:
@main
struct MyApp: App {
@State var rootDirectory: URL
@State var selectedItem: URL
@State var projectNavItems: [NavigationItem] = []
@State var jotNavItems: [NavigationItem] = []
@State var importerIsPresented: Bool = false
let fileManager = FileManager.default
init() {
rootDirectory = URL(string: FileManager.default.currentDirectoryPath)!
selectedItem = URL(string: FileManager.default.currentDirectoryPath)!.appendingPathComponent("README.md")
}
var body: some Scene {
WindowGroup {
NavigationSplitView {
TabView {
Tab("Projects", systemImage: "tray.and.arrow.down.fill") {
List(projectNavItems, selection: $selectedItem) {
// Changing this NavigationLink line to Text($0.title) makes no difference
NavigationLink($0.title, value: $0.id)
}
}
Tab("Jots", systemImage: "tray.and.arrow.up.fill") {
List(jotNavItems, selection: $selectedJot) {
// Can be written as Text($0.title) with no change in behavior
NavigationLink($0.title, value: $0.id)
}
}
}
} detail: {
Editor(for: selectedItem)
}
.fileImporter(
isPresented: $importerIsPresented,
allowedContentTypes: [UTType.folder],
allowsMultipleSelection: false
) { result in
// Code that gets a security scoped resource and populates the
// projectNavItems: [NavItem] and jotNavItems: [NavItem]
// arrays
}
}
.commands(content: {
CommandGroup (before: .newItem) {
Button("Open Journal...") {
importerIsPresented.toggle()
}
}
})
}
}
The error only happens when both Tab views are populated by a List. If the Tab view have different child components, say a List, and a ForEach of Text components, switching between the tabs doesn't produce this error. List views with Text child components also produce this error.
Here are screenshots of the running application
Once the user selects a directory, we see the first Tab > List component populated by contents from the projectNavItems array:
Clicking on the 'Jots' tab switches to the appropriate tab and correctly lists the items in the jotNavItems array, except there are additional lines, seemingly showing that there's an issue.
Clicking back on the 'Projects' tab switches back, but now the List shows only one of the items from the projectNavItems array.
Finally, clicking on 'Jots' again causes the errors to print in the console and interactivity with the tab components ceases. Last screenshot is representative of this state as the application FAULTS.
This seems like a bug in SwifUI, wondering what workarounds I might be able to implement.
I can provide the full backtrace, I cropped it for content length.
