UIContextMenuInteraction not working if view is originally offscreen
I’m having a weird UIKit problem. I have a bunch of views in a UIScrollView and I add a UIContextMenuInteraction to all of them when the view is first loaded. Because they're in a scroll view, only some of the views are initially visible. The interaction works great for any of the views that are initially on-screen, but if I scroll to reveal new subviews, the context menu interaction has no effect for those. I used Xcode's View Debugger to confirm that my interaction is still saved in the view's interactions property, even for views that were initially off-screen and were then scrolled in. What could be happening here?

update UIKit view when viewDidLayoutSubviewsCallback from swiftUI wrapper gets call
Hello team i notice that we have a problem in our app that every time the user opens a Textfield the app freezes when the keyboard appears, this behavior was tracked down and it's a UI breaking design on a UIView [this view it's expandable and is original size is 80] [when it gets expanded 206.33] this is the view code I change the colors to easy check the other's views created inside private lazy var sharedUIPlaybackView: UIView = { let containerView = UIView().withAutoLayout() let propertySearchCriteria = PropertySearchCriteriaBuilder(hotelSearchParameters: viewModel.hotelSearchParameters).criteria var swiftUIView: SwiftUIView<LodgingPlaybackWrapper>! = nil swiftUIView = SwiftUIView( LodgingPlaybackWrapper(propertySearchCriteria: propertySearchCriteria, playbackUpdateNotificationSender: playbackUpdateNotificationSender, componentHandler: { [weak self] componentId in self?.componentReady(componentId) }), viewDidLayoutSubviewsCallback: { [weak self] in let extraPadding = self?.playbackViewExtraPadding ?? Spacing.spacing8x let newHeight = swiftUIView.frame.size.height + extraPadding // if newHeight != self?.sharedUIPlaybackViewHeightConstraint?.constant { // self?.sharedUIPlaybackViewHeightConstraint?.constant = 206.33 // }else { // self?.sharedUIPlaybackViewHeightConstraint?.constant = 80 // } } ).withAutoLayout().withAccessibilityIdentifier("test") // sharedUIPlaybackViewHeightConstraint = containerView.heightAnchor.constraint(equalToConstant: 0) // sharedUIPlaybackViewHeightConstraint?.isActive = true containerView.backgroundColor = .blue swiftUIView.backgroundColor = .red containerView.addSubview(swiftUIView) containerView.addConstraints([ swiftUIView.topAnchor.constraint(equalTo: containerView.topAnchor, constant: playbackViewTopConstant), swiftUIView.leadingAnchor.constraint(equalTo: containerView.leadingAnchor, constant: Spacing.spacing4x), swiftUIView.trailingAnchor.constraint(equalTo: containerView.trailingAnchor, constant: -Spacing.spacing4x), swiftUIView.bottomAnchor.constraint(equalTo: containerView.bottomAnchor, constant: -Spacing.spacing3x), swiftUIView.heightAnchor.constraint(equalToConstant: 206.33) ]) return containerView }() old devs created this function viewDidLayoutSubviewsCallback to connect user interaction on the wrapper and used on UIKit. this is the part where the math on the function gets weird and messed up the code by crashing the view viewDidLayoutSubviewsCallback: { [weak self] in let extraPadding = self?.playbackViewExtraPadding ?? Spacing.spacing8x let newHeight = swiftUIView.frame.size.height + extraPadding if newHeight != self?.sharedUIPlaybackViewHeightConstraint?.constant { self?.sharedUIPlaybackViewHeightConstraint?.constant = newHeight } } ).withAutoLayout().withAccessibilityIdentifier("test") sharedUIPlaybackViewHeightConstraint = containerView.heightAnchor.constraint(equalToConstant: 0) sharedUIPlaybackViewHeightConstraint?.isActive = true I commented this math because is crashing the app and instead of giving a dynamical height I placed as a constant constraint as default height this is how I solved the problem of the UI, but I still need to update the view each time the user clicks and gets call by the method viewDidLayoutSubviewsCallback what can I do? I tried to add like a conditional on the method if newHeight == 80 { containerView.addConstraints([ swiftUIView.heightAnchor.constraint(equalToConstant: 80.0) ]) containerView.layoutIfNeeded() } else { containerView.addConstraints([ swiftUIView.heightAnchor.constraint(equalToConstant: 206.33) ]) containerView.layoutIfNeeded() } like this but it didn't work [this is how it looks with the constant value of 206.33] [when it gets open looks good]

Vibrancy effect not applied to context menu UIImages rendered in template mode
Our Apple TV provides UIImages with renderingMode forced to .alwaysTemplate (the images are also configured with "Render As" to "Template image" in the Asset catalog) to UIActions as UIMenuElement when building a UICollectionView UIContextMenuConfiguration. Problem: these images are not displayed with vibrancy effect by the system. The issue does not occur with system images (SVG from SF Catalog). Here is a screenshot showing the issue with custom images ("Trailer" and "Remove from favourites"): I don't know the underlying implementation of the context menu items image but UIImageView already implements the tintColorDidChange() method and the vibrancy should work if the UIImage is rendered as template. According to my tests, the vibrancy is correctly applied when using Symbols sets instead of Images sets but I understand that custom images rendered as template should support it as-well, shouldn't they?

Unable to Add Accessibility Trait to UISegmentedControl
I’m trying to add the .header accessibility trait to a UISegmentedControl so that VoiceOver recognizes it accordingly. However, setting the trait using the following code doesn’t seem to have any effect: segmentControl.accessibilityTraits = segmentControl.accessibilityTraits.union(.header) Even after applying this, VoiceOver doesn’t announce it as a header. Is there any workaround or recommended approach to achieve this?

How can I check applicationState by tap anps push cards?
when I implementation the UNUserNotificationCenterDelegate func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -&gt; Void) { var status = "" if (UIApplication.shared.applicationState == .active) { status = "active" } else if (UIApplication.shared.applicationState == .background) { status = "background" } else if (UIApplication.shared.applicationState == .inactive) { status = "inactive" } completionHandler() } I find that UIApplication.shared.applicationState == .background this case can not execute when application is in background。 why applicationState is inactive not background?

detecting modifier keys using UITextFieldDelegate protocol
I have a UITextField in my application, and I want to detect all the keys uniquely to perform all relevant task. However, there is some problem in cleanly identifying some of the keys. I m not able to identify the backspace key press in the textField(_:shouldChangeCharactersIn:replacementString:) method. Also I don't know how to detect the Caps Lock key. I am intending to so this because I want to perform some custom handling for some keys. Can someone help me with what is the way of detecting it under the recommendation from apple. Thanks in advance. Note: checking for replacementString parameter in shouldChangeCharactersIn method for empty does not help for backspace detection as it overlaps with other cases.

UINavigtionController as a child view leaves an unwanted gap
I have a situation where I need to add a UINavigationController as a child view controller within another view controller. When I do this, there is a gap between the bottom of the navigation controller's root view controller and the bottom of the navigation controller's own view. This happens even though I am constraining the navigation controller's view to the edges of its superview, not the safe areas. I'd really like to eliminate this gap, but nothing I have tried is working.

How to Ensure Data Privacy with VoiceOver Reading Sensitive Information?
VoiceOver reads out all visible content on the screen, which is essential for visually challenged users. However, this raises a privacy concern—what if a user accidentally focuses on sensitive information, like a bank account password, and it gets read aloud? How can developers prevent VoiceOver from exposing confidential data while still maintaining accessibility? Are there best practices or recommended approaches to handle such scenarios effectively?

Animation Issue: SwiftUI View Not Animating Height Changes in UIHostingController
Hello, I’m developing an app where I display a SwiftUI view inside a UIHostingController embedded within a UIKit ViewController. I’m trying to animate the height of the UIHostingController’s view based on a switch’s value, but the SwiftUI view doesn’t animate at all. Below is a simplified version of my code: class ViewController: UIViewController { private lazy var parentView: UIView = { let view = UIView() view.backgroundColor = .red view.translatesAutoresizingMaskIntoConstraints = false return view }() private lazy var hostingView: UIView = { let testView = TestView() let hostingController = UIHostingController(rootView: testView) let view = hostingController.view! view.translatesAutoresizingMaskIntoConstraints = false return view }() private lazy var button: UISwitch = { let button = UISwitch() button.addTarget(self, action: #selector(onClickSwitch(sender:)), for: .valueChanged) button.translatesAutoresizingMaskIntoConstraints = false return button }() private var hostingViewHeightConstraint: NSLayoutConstraint? override func viewDidLoad() { super.viewDidLoad() view.addSubview(parentView) parentView.addSubview(hostingView) parentView.addSubview(button) NSLayoutConstraint.activate([ parentView.topAnchor.constraint(equalTo: view.topAnchor), parentView.bottomAnchor.constraint(equalTo: view.bottomAnchor), parentView.leadingAnchor.constraint(equalTo: view.leadingAnchor), parentView.trailingAnchor.constraint(equalTo: view.trailingAnchor) ]) NSLayoutConstraint.activate([ hostingView.bottomAnchor.constraint(equalTo: parentView.bottomAnchor), hostingView.leadingAnchor.constraint(equalTo: parentView.leadingAnchor), hostingView.trailingAnchor.constraint(equalTo: parentView.trailingAnchor) ]) hostingViewHeightConstraint = hostingView.heightAnchor.constraint(equalTo: parentView.heightAnchor, multiplier: 0.5) hostingViewHeightConstraint?.isActive = true NSLayoutConstraint.activate([ button.centerXAnchor.constraint(equalTo: parentView.centerXAnchor), NSLayoutConstraint(item: button, attribute: .centerY, relatedBy: .equal, toItem: parentView, attribute: .centerY, multiplier: 0.25, constant: 0) ]) } @objc func onClickSwitch(sender: UISwitch) { hostingViewHeightConstraint?.isActive = false let multiplier: CGFloat = sender.isOn ? 0.25 : 0.5 hostingViewHeightConstraint = hostingView.heightAnchor.constraint(equalTo: parentView.heightAnchor, multiplier: multiplier) hostingViewHeightConstraint?.isActive = true UIView.animate(withDuration: 0.3) { self.view.layoutIfNeeded() } } } I’m looking for the behavior demonstrated in the video below: Does anyone have suggestions on how to achieve this?

How to Enable Group Navigation Behavior for Custom Views in VoiceOver?
In VoiceOver, when using Group Navigation style, the cursor first focuses on the semantic group. To navigate inside the group, a two-finger swipe (left or right) can be used. This behavior works for default containers like the Navigation Bar, Tab Bar, and Tool Bar. How can I achieve the same behavior for a custom view? I tried setting accessibilityContainerType = .semanticGroup, but it only works for Mac Catalyst. Is there an equivalent approach for iOS?

SensorKit Data Not Retrieving
I have received permission from Apple to access SensorKit data for my app. I have granted all necessary permissions, but no data is being retrieved. The didCompleteFetch method is being called, but I’m unsure where to find event data like Device Usage and Ambient Light. Additionally, the didFetchResult method is never called. Could anyone please assist me in resolving this issue? Any guidance or troubleshooting steps would be greatly appreciated. import SensorKit class ViewController: UIViewController, SRSensorReaderDelegate { let store = SRSensorReader(sensor: .deviceUsageReport) override func viewDidLoad() { super.viewDidLoad() requestSensorAuthorization() } func requestSensorAuthorization() { var sensors: Set<SRSensor> = [ .accelerometer, .deviceUsageReport, .messagesUsageReport, .visits, .keyboardMetrics, .phoneUsageReport, .ambientLightSensor ] if #available(iOS 16.4, *) { sensors.insert(.mediaEvents) } SRSensorReader.requestAuthorization(sensors: sensors) { error in if let error = error { print("Authorization failed: \(error.localizedDescription)") } else { self.store.startRecording() self.requestSensorData() print("Authorization granted for requested sensors.") } } } func requestSensorData() { let fromTime = SRAbsoluteTime.fromCFAbsoluteTime(_cf: Date().addingTimeInterval(-60 * 60).timeIntervalSinceReferenceDate) let toTime = SRAbsoluteTime.fromCFAbsoluteTime(_cf: Date().timeIntervalSinceReferenceDate) let request = SRFetchRequest() request.from = fromTime request.to = toTime request.device = SRDevice.current store.fetch(request) store.delegate = self } func sensorReader(_ reader: SRSensorReader, didCompleteFetch fetchRequest: SRFetchRequest) { print("Fetch request completed: \(fetchRequest.from) to \(fetchRequest.to)") Task { do { let samples = try await reader.fetch(fetchRequest) print("Samples count: \(samples)") } catch { print("Error Fetching Data: \(error.localizedDescription)") } } } func sensorReader(_ reader: SRSensorReader, fetching fetchRequest: SRFetchRequest, didFetchResult result: SRFetchResult<AnyObject>) -> Bool { print(result) return true } }

Best Way to Navigate to the Top Element Using VoiceOver
I’m currently focused on an element at the bottom of the screen. What is the proper way to quickly navigate to the top element? By default, there’s a four-finger single tap to move to the first element, but should I use the Rotor action instead to focus on the element I need? For example, in the Contacts app while adding a new contact, if I enter a value in a field at the bottom, there’s no quick way to directly save the contact. I have to manually navigate all the way to the top to tap the Done button, which feels a bit inconvenient. Is there a better way to handle this using VoiceOver?

PHPickerViewController No Auto Focus
The issue is, I cannot auto acquire bluetooth keyboard focus in PHPickerViewController after enabling 'Full Keyboard Access' in my IPhone 14 with iOS version 18.3.1. The keyboard focus in PHPickerViewController will show, however, after I tapped on the blank space of the PHPickerViewController. How to make the focus on at the first place then? I'm using UINavigationController and calling setNavigationBarHidden(true, animated: false). Then I use this controller to present PHPickerViewController using some configuration setup below. self.configuration = PHPickerConfiguration() configuration.filter = .any(of: filters) configuration.selectionLimit = selectionLimit if #available(iOS 15.0, *), allowOrdering { configuration.selection = .ordered } configuration.preferredAssetRepresentationMode = .current Finally I set the delegate to PHPickerViewController and call UINavigationController.present(PHPickerViewController, animated: true) to render it. Also I notice animation showing in first video then disappear.

How to Receive Callbacks for UIAccessibilityAction Methods Like accessibilityPerformMagicTap()?
I’ve tried implementing the accessibilityPerformMagicTap() method in a specific UIViewController, its view, and even in AppDelegate, but I am not receiving any callbacks. I directly overrode this method in the mentioned areas, but it never gets triggered when performing a magic tap. How can I properly observe and handle the accessibilityPerformMagicTap() action?

SwiftUI accessibility when embedded in UIKit
Hello, I struggle to do some UI testing using accessibility identifiers when I wrap some SwiftUI view using UIHostingController (our app is mainly coded using UIKit). Considering this SwiftUI view (simplified for this post): HStack { Text(self.title.uppercased()) .albusTheme(.header) .lineLimit(self.isMultiline ? nil : 1) .multilineTextAlignment(.leading) .accessibilityAddTraits(.isStaticText) .accessibilityIdentifier("section_title") } This view and its controller are embedded as a UITableViewHeaderFooterView in a UITableView. This is an extract of recursiveDescription output: | | | | | | <_UITableViewHeaderFooterContentView: 0x1076ad720; frame = (0 0; 393 40); layer = <CALayer: 0x6000006b1720>> | | | | | | | <_TtGC13ListComponent19SwiftUIFieldContentV20ListComponentLibrary17FormSectionHeader_: 0x1076ab980; baseClass = UIControl; frame = (0 0; 393 40); layer = <CALayer: 0x6000006b1da0>> | | | | | | | | <_TtGC7SwiftUI14_UIHostingViewV20ListComponentLibrary17FormSectionHeader_: 0x1078f9600; frame = (0 0; 393 40); gestureRecognizers = <NSArray: 0x600000e25d70>; backgroundColor = UIExtendedSRGBColorSpace 0.0666667 0.133333 0.227451 1; layer = <SwiftUI.UIHostingViewDebugLayer: 0x6000006b19a0>> | | | | | | | | | <_TtCOCV7SwiftUI11DisplayList11ViewUpdater8Platform13CGDrawingView: 0x106985550; frame = (16 12.6667; 147.667 14.6667); anchorPoint = (0, 0); opaque = NO; autoresizesSubviews = NO; layer = <_TtCOCV7SwiftUI11DisplayList11ViewUpdater8PlatformP33_65A81BD07F0108B0485D2E15DE104A7514CGDrawingLayer: 0x6000026b8240>> CGDrawingView seems to hide the underlying view hierarchy. Is there a way to access accessibility settings using the integration of SwiftUI in UIKit?
