Platform UIKit iOS UIActivityViewController Environment Device (issue reported): iPhone 16 iOS Version: 26.2 App Type: UIKit / Swift (standard modal presentation of UIActivityViewController) Summary When presenting UIActivityViewController to share a CSV file, the share sheet does not allow vertical scrolling, making lower actions (including Save to Files) unreachable. The same flow works correctly when sharing a PDF, and the issue cannot be reproduced on other test devices. Steps to Reproduce Launch the app and log in Navigate to More → Reports Tap Export Report Choose Export Report (CSV) Observe the share sheet Expected Result The user should be able to vertically scroll the share sheet All share actions (including Save to Files) should be reachable Actual Result Share sheet opens but vertical scrolling is disabled Lower options (including Save to Files) are not reachable No crash or console errors

I run into a layout problem where I cannot center an image inside ScrollView which is also inside Navigation Controller. The problem is surely the fact that there is a navigation bar because using this view without NavigationContoller works fine and the image is centered but I don’t know how to account for the space that navigation bar takes up. Here is the code: import UIKit class PhotoViewController: UIViewController { var photoName: String private lazy var photoView = { let image = UIImageView() image.translatesAutoresizingMaskIntoConstraints = false image.contentMode = .scaleAspectFit image.clipsToBounds = true return image }() var photoViewBottomConstraint: NSLayoutConstraint? var photoViewLeadingConstraint: NSLayoutConstraint? var photoViewTopConstraint: NSLayoutConstraint? var photoViewTrailingConstraint: NSLayoutConstraint? private lazy var scrollView = { let sv = UIScrollView() sv.translatesAutoresizingMaskIntoConstraints = false return sv }() override func viewDidLoad() { super.viewDidLoad() setupUI() } override func viewWillLayoutSubviews() { super.viewWillLayoutSubviews() updateMinZoomScaleForSize(view.bounds.size) } func updateMinZoomScaleForSize(_ size: CGSize) { let widthScale = size.width / photoView.bounds.width let heightScale = size.height / photoView.bounds.height let minScale = min(widthScale, heightScale) scrollView.minimumZoomScale = minScale scrollView.zoomScale = minScale } func setupUI() { photoView.image = UIImage(named: photoName) scrollView.delegate = self view.addSubview(scrollView) scrollView.addSubview(photoView) setupConstraints() } func setupConstraints() { NSLayoutConstraint.activate([ scrollView.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor), scrollView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor), scrollView.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor), scrollView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor) ]) photoViewLeadingConstraint = NSLayoutConstraint( item: photoView, attribute: .leading, relatedBy: .equal, toItem: scrollView, attribute: .leading, multiplier: 1, constant: 0 ) photoViewTopConstraint = NSLayoutConstraint( item: photoView, attribute: .top, relatedBy: .equal, toItem: scrollView, attribute: .top, multiplier: 1, constant: 0 ) photoViewTrailingConstraint = NSLayoutConstraint( item: photoView, attribute: .trailing, relatedBy: .equal, toItem: scrollView, attribute: .trailing, multiplier: 1, constant: 0 ) photoViewBottomConstraint = NSLayoutConstraint( item: photoView, attribute: .bottom, relatedBy: .equal, toItem: scrollView, attribute: .bottom, multiplier: 1, constant: 0 ) photoViewLeadingConstraint?.isActive = true photoViewTopConstraint?.isActive = true photoViewTrailingConstraint?.isActive = true photoViewBottomConstraint?.isActive = true } init(photoName: String) { self.photoName = photoName super.init(nibName: nil, bundle: nil) } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } } extension PhotoViewController: UIScrollViewDelegate { func viewForZooming(in scrollView: UIScrollView) -> UIView? { photoView } func scrollViewDidZoom(_ scrollView: UIScrollView) { updateConstraintsForSize(view.bounds.size) } func updateConstraintsForSize(_ size: CGSize) { let yOffset = max(0, (size.height - photoView.frame.height) / 2) photoViewTopConstraint?.constant = yOffset photoViewBottomConstraint?.constant = yOffset let xOffset = max(0, (size.width - photoView.frame.width) / 2) photoViewLeadingConstraint?.constant = xOffset photoViewTrailingConstraint?.constant = xOffset view.layoutIfNeeded() } }

I am building an app for iOS and MacCatalyst that indexes files by storing their local paths. Because the app relies on the file remaining at its original location, I only want to accept items that can be opened in place. I am struggling to determine if an item is "Open In Place" compatible early in the drag-and-drop lifecycle. Specifically: In dropInteraction(_:canHandle:) and dropInteraction(_:sessionDidUpdate:), calling itemProvider.registeredTypeIdentifiers(fileOptions: [.openInPlace]) returns an empty array. Only once the drop is actually committed in dropInteraction(_:performDrop:) does that same call return the expected type identifiers. This creates a poor user experience. I want to validate the "In Place" capability at the very start of the session so the drop target only activates for valid files. If an item is ephemeral (like a dragged photo from the Photos app or a temporary export), the drop zone should not react at all. How can I reliably detect if an NSItemProvider supports .openInPlace before the performDrop delegate method is called?

Hi all, I’m seeing a lifecycle behavior change on iOS 26.0 (and up). While my app is in the foreground and active, pressing the hardware Lock button triggers didBecomeActive callbacks/notifications even though the app is transitioning away from active state. I’m observing this sequence: willResignActive didBecomeActive willResignActive didEnterBackground This happens for: • UISceneDelegate.sceneDidBecomeActive(:) • UIApplicationDelegate.applicationDidBecomeActive(:) • UIApplication.didBecomeActiveNotification On iOS 18 (same app, same code) I do not see didBecomeActive in the middle of locking/backgrounding. Problem is reproduced on totally new project. I would expect a normal transition to background: • willResignActive → didEnterBackground …and no extra didBecomeActive between them. I have “became active” logic (refresh UI/state, resume timers, analytics). On iOS 26.0 this logic runs unexpectedly during locking, causing unnecessary work and incorrect state transitions. Is this callback ordering expected on iOS 26.0 when pressing the Lock button? If expected, what’s the recommended way to detect a “real” activation (and avoid transient didBecomeActive during locking/backgrounding)? If this is a regression, is there a known workaround or best practice?

What works let backButton = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil) backButton.hidesSharedBackground = true self.navigationItem.rightBarButtonItem = backButton // or self.navigationItem.leftBarButtonItem = backButton What doesn't work let backButton = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil) backButton.hidesSharedBackground = true self.navigationItem.backBarButtonItem = backButton I've tried setting this property on all possible permutations and combinations e.g. Inside navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) and pushViewController(_ viewController: UIViewController, animated: Bool) of a custom UINavigationController to make sure. Expected vs Actual behavior Setting hidesSharedBackground = true should remove the glass background from both regular bar button items and back bar button items but it has no effect on backBarButtonItem. Additional context I’m aware of the UIDesignRequiresCompatibility Info.plist key, but I’m looking for a programmatic solution if there is one. The goal is to remove the glass background from back buttons.

My app start up has became horrid. It takes 1 minute to open SQLlite database for my rust core. Impossible to work... I have Address Sanitizer, Thread Perf Checker and Thread Sanitizer disabled...

I just found a weird bug: If you place a Text view using .foregroundStyle(.secondary), .tertiary, or other semantic colors inside a ScrollView, and apply a Material background clipped to an UnevenRoundedRectangle, the text becomes invisible. This issue does not occur when: The text uses .primary or explicit colors (e.g., .red, Color.blue), or The background is clipped to a standard shape (e.g., RoundedRectangle). A minimal reproducible example is shown below: ScrollView{ VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello World.") .font(.system(size: 15)) .foregroundStyle(.quinary) } } .padding() .frame(height: 100) .background(Material.regular) .clipShape(UnevenRoundedRectangle(topLeadingRadius: 10,bottomLeadingRadius: 8,bottomTrailingRadius:8, topTrailingRadius: 8))

I had take screenshots by following code let scenes = UIApplication.shared.connectedScenes let windowScene = scenes.first as? UIWindowScene let window = windowScene?.windows.first self.uiImage = window?.rootViewController?.view!.getImage(rect: rect) View has two views. One is ImageView contains some image and overlay of image detection results with .overlay. another view is InfoView contains several info and button which above code fired. on iOS 17, I can take screenshots as I saw, but on iOS26, missing on image of ImageView. Overlay(detected rectangle) in Imageview and InfView can be taken. How can I take screenshots as I saw on iOS26?(iPad)

I’ve notice that in Maps, some pins contain images and do not have the little triangle at the bottom of it, yet they still animate the same when clicked. How could this be achieved? I believe the name of this annotation is MKMapFeatureAnnotation. I've tried this and it did not give the same result. I'm able to create a custom MKMarkerAnnotationView but it does not animate the same (balloon animation like the MKMapFeatureAnnotation). I was looking forward to create a custom MKMapFeatureAnnotation similar in design which would animate the same. Unfortunately, I cannot create a custom MKMapFeatureAnnotation because everything is privated

When using UITraitBridgedEnvironmentKey to pass a trait value to the swift environment, it causes a crash when trying to access the value from the environment. The issue seems to be related to how swift uses the UITraitBridgedEnvironmentKey protocol since the crash occurs in swift::_getWitnessTable () from lazy protocol witness table accessor…. It can occur when calling any function that is generic using the UITraitBridgedEnvironmentKey type. I originally encountered the issue when trying to use a UITraitBridgedEnvironmentKey in SwiftUI, but have been able to reproduce the issue with any function with a similar signature. https://developer.apple.com/documentation/swiftui/environmentvalues/subscript(_:)-9zku Steps to Reproduce Requirements for the issue to occur Project with a minimum iOS version of iOS 16 Build the project with Xcode 26 Run on iOS 18 Add the following code to a project and call foo(key: MyCustomTraitKey.self) from anywhere. @available(iOS 17.0, *) func foo<K>(key: K.Type) where K: UITraitBridgedEnvironmentKey { // Crashes before this is called } @available(iOS 17.0, *) public enum MyCustomTraitKey: UITraitBridgedEnvironmentKey { public static let defaultValue: Bool = false public static func read(from traitCollection: UITraitCollection) -> Bool { false } public static func write(to mutableTraits: inout UIMutableTraits, value: Bool) {} } // The crash will occur when calling this. It can be added to a project anywhere // The sample project calls it from scene(_:willConnectTo:options:) foo(key: MyCustomTraitKey.self) For example, I added it to the SceneDelegate in a UIKit Project class SceneDelegate: UIResponder, UIWindowSceneDelegate { var window: UIWindow? func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) { if #available(iOS 17, *) { // The following line of code can be placed anywhere in a project, `SceneDelegate` is just a convenient place to put it to reproduce the issue. foo(key: MyCustomTraitKey.self) // ^ CRASH: Thread 1: EXC_BAD_ACCESS (code=1, address=0x10) } } } Actual Behaviour The app crashes with the stack trace showing the place calling foo but before foo is actually called. (ie, a breakpoint or print in foo is never hit) #0 0x000000019595fbc4 in swift::_getWitnessTable () #1 0x0000000104954128 in lazy protocol witness table accessor for type MyCustomTraitKey and conformance MyCustomTraitKey () #2 0x0000000104953bc4 in SceneDelegate.scene(_:willConnectTo:options:) at .../SceneDelegate.swift:20 The app does not crash when run on iOS 17, or 26 or when the minimum ios version is raised to iOS 17 or higher. It also doesn't crash on iOS 16 since it's not calling foo since UITraitBridgedEnvironmentKey was added in iOS 17. Expected behaviour The app should not crash. It should call foo on iOS 17, 18, and 26.

Our app supports UIScene. As a result, launchOptions in application(_:didFinishLaunchingWithOptions:) is always nil. However, the documentation mentions that UIApplication.LaunchOptionsKey.location should be present when the app is launched due to a location event. Given that our app is scene-based: How can we reliably determine whether the app was launched due to a location update, geofence, or significant location change? Is there a recommended pattern or API to detect this scenario in a Scene-based app lifecycle? This information is critical for us to correctly initialize location-related logic on launch. Relevant documentation: https://developer.apple.com/documentation/corelocation/cllocationmanager/startmonitoringsignificantlocationchanges()

1. Summary In a hybrid iOS app using WKWebView (Angular + Capacitor), after programmatically blurring an element and connecting a Bluetooth keyboard, pressing Ctrl+Home or Ctrl+End causes the app to crash. The crash stack shows the issue occurs inside UIKit keyboard handling (UITextInteractionSelectableInputDelegate _moveToStartOfLine), indicating a system-level bug. 2. Steps to Reproduce Open the hybrid app containing a WKWebView. Blur the input (programmatically). Connect a Bluetooth keyboard. Press Ctrl + Home or Ctrl + End. Expected result: No crash. The command should be ignored if no text input is active. Actual result: App crashes immediately. 3.

Hi there. I want to use Adobe XD for designing and prototyping apps, and I would like to get the UIKit design resources working. I downloaded it and tried to open it with Adobe XD, but it threw this error: There was an error opening the file Apple iOS 26 UI Kit.sketch (Error code: 115) I really prefer to use the UIKit in Adobe XD rather than paying for Figma or Sketch. Thanks. Apple Design Resources

In iOS 26, keyboardLayoutGuide does not provide the correct constraint when using third-party input method. A demo’s source code is attached to FB18594298 to illustrate the issue. The setup includes: An inputAccessoryView above keyboard An input box anchored to the top of the inputAccessoryView using the following constraint: [self.view.keyboardLayoutGuide.topAnchor constraintEqualToAnchor:self.inputBoxContainerView.bottomAnchor] Expected Behavior: Before iOS 26, when keyboard toggled by clicking the input box, the input box should move above the inputAccessoryView. Actual Behavior: However, on iOS 26, when switching to a third-party IME (e.g. 百度输入法baidu，搜狗输入法sogou，微信输入法wechat), then click the input box, the input box is above the keyboard instead of the inputAccessoryView, and is covered by the inputAccessoryView.

I am struggling to change the tint of the back button in an UINavigationItem. In iOS 18.6 it looks like this while on iOS 26 the same looks like this I can live without the Dictionary but I'd like to get the blue color back. In viewDidLoad() I have tried navigationItem.backBarButtonItem?.tintColor = .link but this did not work since navigationItem.backBarButtonItem is nil. My second attempt was navigationController?.navigationBar.tintColor = .link but this didn't work either. I have even set the Global Tint to Link Color but this had no effect either. Does anyone have an idea how to change the tint of the back button in an UINavigationItem on iOS 26?

After reviewing the following Apple Technote, I have confirmed the statement below: https://developer.apple.com/documentation/technotes/tn3187-migrating-to-the-uikit-scene-based-life-cycle In the next major release following iOS 26, UIScene lifecycle will be required when building with the latest SDK; otherwise, your app won’t launch. While supporting multiple scenes is encouraged, only adoption of scene life-cycle is required. Based on the above, I would appreciate it if you could confirm the following points: Is my understanding correct that the term “latest SDK” refers to Xcode 27? Is it correct that an app built with the latest SDK (Xcode 27, assuming the above understanding is correct) will not launch without adopting the UIScene lifecycle, with no exceptions? Is it correct that an app built with Xcode 26 without UIScene lifecycle support will still launch without issues on an iPhone updated to iOS 27?

Setup: I have a segment view with 3 segments, and the last on (at index 2) is disabled. Issue: When I drag the liquid glass handle of the segment view from what was previously selected to the disabled segment, the liquid glass handle freezes mid-air. Workaround: I can still interact with the handle and manually restore its position, or tap on any other segment to restore its position. Notes: I'm using UIKit, and no extra customizations are applied. class ViewController: UIViewController { @IBOutlet weak var segmentView: UISegmentedControl! override func viewDidLoad() { super.viewDidLoad() segmentView.removeAllSegments() let segments = ["Option 1", "Option 2", "Option 3"] for (index, title) in segments.enumerated() { segmentView.insertSegment(withTitle: title, at: index, animated: false) } // Select the first one by default segmentView.selectedSegmentIndex = 0 // Disable the last segment segmentView.setEnabled(false, forSegmentAt: 2) } }

Hello! I'm making a list of app icons for users to choose, but when I increase or decrease the font size, the image is still in the same spot and isn't centered vertically with the text. I have it initialized with a frame with hard-coded values, but I was wondering if there was a better way of doing it, such as with constraints or some sort of image scaling. I've provided code blocks and an image of what is happening. ImageView Configuration // App Icon Image UIImageView *appIconImageView = [[UIImageView alloc] initWithFrame: CGRectMake(12.5, 17, 22.5, 22.5)]; // Configurations UIImageSymbolConfiguration *multicolorConfiguration = [UIImageSymbolConfiguration configurationPreferringMulticolor]; UIImageSymbolConfiguration *sizeConfiguration = [UIImageSymbolConfiguration configurationWithScale: UIImageSymbolScaleSmall]; UIImageSymbolConfiguration *appIconConfiguration = [multicolorConfiguration configurationByApplyingConfiguration: sizeConfiguration]; appIconImageView.preferredSymbolConfiguration = appIconConfiguration; appIconImageView.contentMode = UIViewContentModeScaleAspectFill; self.appIconImage = appIconImageView; [appIconImageView release]; ImageView Constraints [self.appIconImage.firstBaselineAnchor constraintEqualToAnchor: self.contentView.firstBaselineAnchor constant: 5.0], [self.appIconImage.leadingAnchor constraintEqualToAnchor: self.contentView.layoutMarginsGuide.leadingAnchor], // Label [self.colorLabel.leadingAnchor constraintEqualToAnchor:self.appIconImage.trailingAnchor constant: 10], [self.colorLabel.trailingAnchor constraintEqualToAnchor:self.contentView.layoutMarginsGuide.trailingAnchor], [self.colorLabel.topAnchor constraintEqualToAnchor: self.contentView.layoutMarginsGuide.topAnchor], [self.colorLabel.bottomAnchor constraintEqualToAnchor: self.contentView.layoutMarginsGuide.bottomAnchor], Image

We are seeing a strange lifecycle issue on multiple MDM-managed iPads where application(_:didFinishLaunchingWithOptions:) is not called after the device is idle overnight. Even if we terminate the app manually via the app switcher, the next morning the system does not perform a cold launch. Instead, the app resumes directly in: applicationDidBecomeActive(_:) This causes all initialization logic that depends on didFinishLaunching to be completely skipped. This behavior is consistent across four different supervised MDM devices. Environment Devices: iPads enrolled in MDM (supervised) iOS version: 18.3 Xcode: 16.4 macOS: Sequoia 15.7.2 App type: Standard UIKit iOS app App: Salux Audiometer (App Store app) Expected Behavior If the app was terminated manually using the app switcher, the next launch should: Start a new process Trigger application(_:didFinishLaunchingWithOptions:) Follow the normal cold-start lifecycle Actual Behavior After leaving the iPad idle overnight (8–12 hours): The next launch skips didFinishLaunching The app resumes directly in applicationDidBecomeActive No new process is started App behaves as if it had been suspended, even though it was manually terminated Logs (Relevant Extracts) Day 1 — Normal cold launch [12:06:44.152 PM] PROCESS_STARTED [12:06:44.214 PM] DID_FINISH_LAUNCHING_START launchOptions=[] [12:06:44.448 PM] DID_FINISH_LAUNCHING_END We then used the app and terminated it via app switcher. Day 2 — Unexpected resume without cold start [12:57:49.328 PM] APP_DID_BECOME_ACTIVE No PROCESS_STARTED No didFinishLaunching No cold-start logs This means the OS resumed the app from a previous state that should not exist. Reproducible Steps Use an MDM-enrolled iPad. Launch the app normally. Terminate it manually via the multitasking app switcher. Leave the device idle overnight (8–12 hours). Launch the app the next morning. Observe that: didFinishLaunching does not fire applicationDidBecomeActive fires directly Questions for Apple Engineers / Community Is this expected behavior on MDM-supervised devices in iOS 18? Are there any known OS-level changes where terminated apps may be revived from disk/memory? Could MDM restrictions or background restoration policies override app termination? How can we ensure that our app always performs a clean initialization when launched after a long idle period? Additional Information We have full logs from four separate MDM iPads showing identical behavior. Happy to share a minimal reproducible sample if required.
