Overview I have the following view hierarchy that mixes SwiftUI and UIKit: AccordionView └─ VStack ├─ Text ├─ Button └─ UIViewRepresentable └─ UIStackView ├─ UILabel └─ UILabel When tapping the button, the UIViewRepresentable hides and shows its content. This all works as expected. However, in certain circumstances the view's sizing is rendered with the correct size, but the text can often render incorrectly, despite the frame seemingly looking as though it has enough room to render the text. More info Below you can see the UILabel has the correct frame height (the light grey background and coloured borders) but the text is rendered as though it has infinite width along one line. There's a few configurations of my view hierarchy that seem to have this effect. I've added a playground to the bottom of this post of various configurations to show what does and doesn't work, just copy and paste to see for yourself... It seems of the ones that don't work, there's a couple of reasons why that may be: HostedView and TextViewContainer do not do the following (I think we only need to do one of these things for auto layout/stack views to work effectively): a) implement an intrinsic content size b) return a 'good' size for systemLayoutSizeFitting(). UIHostingController shouldn't use intrinsic size (although I'm sure it should) Something related to setting setContentCompressionResistancePriority() or setContentHuggingPriority() but having played about with this it doesn't seem relevant here... I've played around with everything I can think of here but can't find a solution that works for all, although I'm 99% sure it's one or all of the points above. If there are any UIKit gurus out there that can help that would be great! Ive already spent so much time on this 🫨 Playground Swift Playground

[Submitted as FB21958289] A minimal SwiftUI app logs framework warnings when a bottom bar Menu is used with the system search toolbar item. The most severe issue is logged as a console Fault (full logs below): Adding 'UIKitToolbar' as a subview of UIHostingController.view is not supported and may result in a broken view hierarchy. Add your view above UIHostingController.view in a common superview or insert it into your SwiftUI content in a UIViewRepresentable instead. This appears to be a framework-level SwiftUI/UIKit integration issue, not custom UIKit embedding in app code. The UI may still render, but the warnings indicate an internal hierarchy/layout conflict. This occurs in simulator and physical device. REPRO STEPS Create a new project then replace ContentView with the code below. Run the app. The view uses NavigationStack + .searchable + .toolbar with: ToolbarItem(placement: .bottomBar) containing a Menu DefaultToolbarItem(kind: .search, placement: .bottomBar) EXPECTED RESULT No view hierarchy or Auto Layout warnings in the console. ACTUAL RESULT Console logs warnings such as: "Adding 'UIKitToolbar' as a subview of UIHostingController.view is not supported..."

Since iOS 26, navigationController?.toolbar no longer appears in the view hierarchy, and UIToolbar itself is not visible in the view tree. Is there currently any supported way to access the toolbar’s container view or its underlying view hierarchy? However, the API itself is not deprecated. https://developer.apple.com/documentation/uikit/uinavigationcontroller/toolbar

Hello. I have an 12 year old app that still has some objective-c code in it. I have a place where i have a flip animation between 2 view controllers that looks like this: [UIView transitionFromView:origView toView:newViewController.view duration:0.5 options:UIViewAnimationOptionTransitionFlipFromRight completion:nil]; It has looked like this since 2012 at least. In our production release, it works prior to 26.1, but in 26.1 and 26.2, the flip is off-center and looks weird. it's like both edges flip the same way. It's a little bit hard to explain. If seen at least 2 other app store apps that i have installed behave this way too, from 26.1 and onwards. Anyone else seen this? Is there anything that can be done about it? Thankful for thoughts.

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()

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?
