I've been looking for a solution to configure the Apple TV remote(s) from the 5th generation and upwards. Some of the basic functionalities are disabling buttons on the physical remote control while maintaining proper functionality on remote controller apps on iOS devices. There seems to be a lack of relevant entitlements in that category, and without it I can't seem to figure out a way to make it work. Any ideas on the matter? Maybe a workaround that allows to configure the Apple TV to work with other remotes? Thank you in advance to anyone that put in thought to my query.

When my CPMapButton is selected/focused, I would like to be able to provide a focusedImage to correctly show the button when the blue focus is shown. Currently I have: What do I need to do to create an image that works more like the panning interface buttons?

There is an issue with SwiftUI where it is incorrectly instantiating the navigation destination view with a new identity for a navigation stack that is being removed. Here is a minimal reproducible example: struct ContentView: View { @State private var signedIn = false var body: some View { if signedIn { navigationStack(isSignedIn: true) } else { navigationStack(isSignedIn: false) } } private func navigationStack(isSignedIn: Bool) -> some View { NavigationStack(path: .constant(NavigationPath([1]))) { EmptyView() .navigationDestination(for: Int.self) { _ in VStack { Text(isSignedIn ? "Signed In" : "Signed Out") .foregroundStyle(Color.red) Button(isSignedIn ? "Sign Out" : "Sign In") { signedIn = !isSignedIn } } .onFirstAppear { print(isSignedIn ? "signed in" : "signed out") } } } } } struct OnFirstAppearView: ViewModifier { @State private var hasAppeared = false var onAppear: () -> Void func body(content: Content) -> some View { content .onAppear { if hasAppeared { return } hasAppeared = true onAppear() } } } extension View { func onFirstAppear(_ onAppear: @escaping () -> Void) -> some View { ModifiedContent(content: self, modifier: OnFirstAppearView(onAppear: onAppear)) } } When you launch the app it will print "signed out", but when you tap to Sign In it will print "signed out" and "signed in". This shows that onAppear is incorrectly being called for a view that is disappearing and worse yet, it is with a new identity. The onFirstAppear modifier was created to help with detecting the identity change of the view. Tested on Xcode 16.4, on simulator using iOS 18.5 and also on physical device using iOS 18.5.

When a user swipes up to see the app switcher, I put a blocking view over my app so the data inside cannot be seen if you flick through the app switcher. I do this by receive notifications（UIApplicationDidBecomeActiveNotification, UIApplicationWillResignActiveNotification） But on my iPhone 16 Pro, iOS 18.4.1 test device, Face ID authentication via LAContext may not always result in App lifecycle notifications.This caused my blocking view not to be removed. any ideas about the notification changes caused by Biometric authentication？

I have a SwiftUI view that I have wrapped using UIHostingController for use within UIKit. Requirement: Within the UIKit environment, I want to get all the subviews of this SwiftUI view and determine whether the images within those subviews have finished loading. For UIKit views, we can use view.subviews to get all the subviews and do the check. However, for SwiftUI views, I found that the view.subviews turns out to be an empty array, making it impossible to do further checks. So the question is How can I get the subviews of a SwiftUI view?

I have a grid setup where I'm displaying multiple images which is working fine. Images are ordered by the date they're added, newest to oldest. I'm trying to set it up so that the user can change the sort order themselves but am having trouble getting the view to update. I'm setting the fetch request using oldest to newest as default when initialising the view, then when its appears updating the sort descriptor struct ProjectImagesListView: View { @Environment(\.managedObjectContext) private var viewContext var project : Project let columns = [ GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible()) ] @FetchRequest var pictures: FetchedResults<Picture> var body: some View { ScrollView { LazyVGrid(columns: columns) { ForEach(pictures) { picture in NavigationLink(destination: ProjectImageDetailView(picture: picture)) { if let pictureData = picture.pictureThumbnailData, let uiImage = UIImage(data: pictureData) { Image(uiImage: uiImage) .resizable() .scaledToFit() .frame(height: 100) } else { Image("missing") .resizable() .scaledToFit() .frame(height: 100) } } } } } .navigationBarTitle("\(project.name ?? "") Images", displayMode: .inline) .onAppear() { guard let sortOrder = getSettingForPhotoOrder() else { return } guard let sortOrderValue = sortOrder.settingValue else { return } NSLog("sortOrderPhotos: \(String(describing: sortOrder.settingValue))") if sortOrderValue == "Newest" { NSLog("sortOrderPhotos: Change from default") let newSortDescriptor = NSSortDescriptor(keyPath: \Picture.dateTaken, ascending: false) pictures.nsSortDescriptors = [newSortDescriptor] } } } func getSettingForPhotoOrder() -> Setting? { let fetchRequest: NSFetchRequest<Setting> = Setting.fetchRequest() fetchRequest.predicate = NSPredicate(format: "name = %@", "photoSortOrder") fetchRequest.fetchLimit = 1 do { let results = try viewContext.fetch(fetchRequest) return results.first } catch { print("Fetching Failed") } return nil } init(project: Project) { self.project = project _pictures = FetchRequest( entity: Picture.entity(), sortDescriptors: [ NSSortDescriptor(keyPath: \Picture.dateTaken, ascending: true) ], predicate: NSPredicate(format: "project == %@", project) ) } }

Is is possible to use the camera in ASWebAuthenticationSession? We want to support signing in with a QR Code in our custom OAuth flow but the browser can't seem to access the camera.

Hello, I've been trying to figure this thing for a while now, but I've not able to find any resolution. I've a UIAlertController object presented as UIAlertControllerStyleActionSheet. It's fairly straightforward code: UIAlertController *listSheet = [UIAlertController alertControllerWithTitle:NSLocalizedStringFromTableInBundle(@"Please Select a Report", nil, [LDKLocalizationTool currentBundle], @"Chart report selector") message:nil preferredStyle:UIAlertControllerStyleActionSheet]; [self.charts enumerateObjectsUsingBlock:^(ChartDefinition *chart, NSUInteger idx, BOOL *stop) { UIAlertAction *anAction = [UIAlertAction actionWithTitle:chart.graphLabel style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) { // handler logic }]; [listSheet addAction:anAction]; }]; // Set the anchor point for the AlertController UIPopoverPresentationController *popoverPresenter = [listSheet popoverPresentationController]; if (popoverPresenter) { popoverPresenter.sourceView = sender; popoverPresenter.sourceRect = [sender bounds]; } // Display the AlertController [self presentViewController:listSheet animated:YES completion:nil]; However, when presented, the action sheet shows up as shown in the attached screenshot. There are no autoLayout constraints or anything like that to cause issues with layout. I'm not sure why it's causing this issue. Any suggestions or help is much appreciated! iPadOS version: 18.4 Xcode version: 16.3 M4 Mac with macOS 15.5

Looking at the superclass of CPImmersiveScene is surprisingly is a UIWindowScene. Is this intentional? Should I treat it as a window scene, and provide an UIWindow for it? Or is it only an implementation detail for managing the internal CPSceneLayerEventWindow and UITextEffectsWindow?

I got 3 PKCanvasView, 2 below the Major one. Users draw lines on the top one, then sync the last stroke to the one underneath. If the stroke crosses two PKCanvasView, we replace the stroke with a bezier curve. If a stroke doesn't cross regions, we sync the stroke to the one below it(B) as if it is drawn directly on B. The problem is if the B is inside a UIScrollview with a zoom scale not 1, the stroke from major to B will shrink or grow. Does anybody have a solution for this please? What I did Also put the major canvas into a uiScrollview, and make sure the zoomScale is the same as the B. for scale >=1, it works as expected, for scale < 1, sometimes it works, sometimes it doesn't. for example, 0.5, 0.6, 0.8, 0.5 doesn't work, 0.6, 0.8 works, I don't know why. What it costs It cost me 16*4 hours for these days. I didn't find a solution. Hopefully, some one can solve it.

Hi, I have a SwiftUI View, that is attached to a 3D object in Reality View. This is supposed to be a HUD for the user to select a few things. I wanted a sub menu for one of the top level buttons. But looks like none of the reasonable choices like Menu, Sheet or Popover work. Is there a known limitation of RealityKit Views where full SwiftUI cannot be used? Or am I doing something wrong? For example, Button { SLogger.info("Toggled") withAnimation { showHudPositionMenu.toggle() } } label: { HStack { Image(systemName: "rectangle.3.group") Text("My Button") } } .popover(isPresented: $showHudPositionMenu, attachmentAnchor: attachmentAnchor) { HudPositionMenuItems(showHudPositionMenu: $showHudPositionMenu, currentHudPosition: $currentHudPosition) } This will print "Toggled" but will not display the MenuItems Popover. If it makes any difference, this is attached to a child of a head tracked entity.

Adding .chartScrollableAxes(.horizontal) to a chart prevents chartYAxisLabel from being positioned top right, over Y axis. We want the label at top right, over the Y-axis, but with chartScrollableAxes it is always top right relative to the initial chartXVisibleDomain, which puts it in the middle of the chart if chartXVisibleDomain < full x domain. import SwiftUI import Charts struct ContentView: View { @State private var numbers = (0..<100) .map { _ in Double.random(in: 0...100) } @State var visibleDomain : Int = 50 var body: some View { Chart(Array(zip(numbers.indices, numbers)), id: \.1) { index, number in LineMark( x: .value("Index", index), y: .value("Number", number) ) } .chartScrollableAxes(.horizontal) .chartXVisibleDomain(length: visibleDomain) .chartScrollPosition(initialX: 70) .chartYAxisLabel(position: .topTrailing, alignment: .center) { /* We want the label at top right, over the Y-axis, but with chartScrollableAxes it is always top right relative to the initial chartXVisibleDomain, which puts it in the middle of the chart if chartXVisibleDomain < full x domain */ Text("units") .foregroundStyle(.red) .fontWeight(.bold) } .padding() } } #Preview { ContentView() }

Can I adjust the color properties of disclosure carets in an Outline Disclosure List view (with NavigationLinks for the list entries) in visionOS? I have color for these carets using .foregroundStyle(.accent) and it works, however, I want to change the “brightness” of those accented color carets.

Since iOS 26, hidesBottomBarWhenPushed no longer works. We have numerous screens in our app which depend on being able to extend content to the bottom of the screen, and this feels like a bug. Consider this example, running the exact same code across iOS 18 and iOS 26. On iOS 18, pushing the button pushes a view controller and the tab bar disappears, on iOS 26, however, pushing the view controller does not hide the tab bar. I've filed this as FB18543961 and attached the sample project.

I just put the TextField on UI and call the NSTextField setString, but it is memory usage is increasing. StoryBoard Objective C put TextField and button to UI set TextField variable to "ABC" in ViewController.h @property (weak) IBOutlet NSTextView* ABC; on button event function //dispatch_sync(dispatch_get_main_queue(), ^{ [_ABC setString:str]; //}); How to block the memory usage increase? Also I was check on Instruments app, and there are many malloc 48bytes, its count is almost same with setString count. Thank you!

I'm trying to create a .pkg installer with productbuild/pkgbuild. But I'd also like to add my custom installer plugin to this. I'm using the following script. I'd like to add my bundle into this script. Since there are no official docs from apple how to do this nor there are a lot of updated resources, here are some things I have tried. adding the following line to Distrubtion.xml <bundle id="pluginid" path="path/to/myplugin.bundle"/> adding component tag to pkgbuild also doesn't do anything --component "path/to/myplugin.bundle" The bundle itself is build with XCode - it is a simple UI for user to type some input in Apple provides documentation for Distribution.xml file, which supports different UI elements but doesn't support text input - docs I have been also looking at this tutorial , it is very outdated but i could still fit it to my needs except the part where the .bundle file needs to be inserted into .pkg. Note - there is no option to view the contents of .pkg file build with pkbuild/productbuild How can i do this process correctly? I would like to link my installer pane plugin to a generic .pkg(with licenses and so on). I'd appreciate any kind of help!

I have a dark background and the initial look of the nav bar is showing like there is a light background. See picture. Has anyone experienced this or know of a solution? If I scroll the table up, it will fix itself and start behaving as I'd expect.

Bringing my iPad app to Mac Catalyst as iPad idiom. Primary interface is a UISplitViewController. Two things I think are bugs unless someone replies with a fix. SplitViewController is setup in two column with left column as sidebar: split.setViewController(primary, for: .primary) split.setViewController(secondary, for: .secondary) split.preferredDisplayMode = .oneBesideSecondary split.preferredSplitBehavior = .tile split.presentsWithGesture = true #if targetEnvironment(macCatalyst) split.primaryBackgroundStyle = .sidebar split.displayModeButtonVisibility = .never #endif The displayMode button aligns vertically with the navigation bar and below the 3 window control buttons (close, minimize, full screen), whereas on other macOS apps using SplitViewController such as Apple Notes app, the displayMode button aligns vertically and just to the right of the the 3 window control buttons (close, minimize, full screen). I downloaded the Apple Example app called Menus that is supposed to be a prime example of a Mac Catalyst app, and I see author must have faced the same bug and instead created their own displayMode button and placed it on the UITitlebar's toolBar. In my secondary ViewController which is a subclass of a UITableViewController, tapping a row, calls show and in a SplitViewController, that pushes another detailVC onto the Nav stack as expected. The UIWindowScene's UITitlebar which appears over the top of the secondary VC looks correct. This detailVC is a subclass of a UITableViewController. Finally, tapping a row in the table of the detailVC calls show but this time, the ViewController is actually a UIHostingViewController wrapping a SwiftUI View. At this point the UIWindowScene's UITitlebar changes appearance and takes on the same lightened color similar to the sidebar (primary) appearance. With UITitlebarTitleVisibility set to hidden and if I set the titlebar.toolbar to nil, (which removes the UITitlebar, there is no appearance issue. Running on iPad, with no UITitlebar, there is no odd lightening experienced when the UIHostingController is shown. I think this has something to do with the UIHostingController within Mac Catalyst.

So I'm dealing with a really obtuse crash that appears to be a stack overflow in an internal SwiftUI code path creating a Color.Resolved. I haven't found anyone one else with this issue online, and I cannot get it to reproduce on my own device. Interestingly enough, it is only happening on 1 device in the field (according to XCode crash logs). Here are some lines from the crashed thread. You can see that my code is never called, and it appears to be starting in some Array equality check checking the equality of colors (which I can't think of anywhere in my app I am doing anyway). You can see from this trace here that it appears to be a recursive call through Color.Resolved and NSColor.withColorAppearance. I don't have any idea how to solve this, but it keeps happening with at least one in-the-field device across multiple app updates. So my whole app is open source on github at https://github.com/msdrigg/roam, but I don't even use NSColor explicitly anywhere except for here which doesn't match the stack trace. I also tried changing the accent color of the app with defaults write com.msdrigg.roam AppleAccentColor -integer 1 to see if that somehow caused the crash, but my app opened up totally fine (and respected the change). Besides this, the only places I think I could be using dynamic colors is I when define an AccentColor and a WidgetBackground color for my app using xcassets, and then I use these colors from SwiftUI. In most of my app I stick to the system colors (Color.gray and such).

A document-based app with NavigationSplitView shows duplicate file navigation controls on iPad. This can be easily replicated by creating a multiplatform app in Xcode. The template app shows this behaviour when running on iPad. This looks very much like a bug.
