Hello, If you add a ManipulationComponent to a RealityKit entity and then continue to add instructions, sooner or later you will encounter a crash with the following error message: Attempting to move entity “%s” (%p) under “%s” (%p), but the new parent entity is currently being removed. Changing the parent/child entities of an entity in an event handler while that entity is already being reassigned is not supported. CoreSimulator 1048 – Device: Apple Vision Pro 4K (B87DD32A-E862-4791-8B71-92E50CE6EC06) – Runtime: visionOS 26.0 (23M336) – Device Type: Apple Vision Pro The problem occurs precisely with this code: ManipulationComponent.configureEntity(object) I adapted Apple's ObjectPlacementExample and made the changes available via GitHub. The desired behavior is that I add entities to ManipulationComponent and then Realitiykit runs stably and does not crash randomly. GitHub Repo Thanks Andre

I work at a school in NYC and have a software idea that could better support the new NYC phone ban law than current market options (i.e. Yondr pouches). Right now at my school, students and staff scan a QR code upon entering the building to indicate that they are in the building. They scan again on the way out to indicate they've left the building. This is super helpful for attendance, particularly in emergency situations (fire drills, etc). Imagine if when students scanned their QR code, it also activated an app similar to Opal or ScreenZen, but with an admin preset whitelisted apps. The idea is that this app would default deny access to all apps on students' phones except the admin preset whitelisted ones such as Phone, Calculator, etc. Depending on the age/needs of the student, other apps like Spotify, or medical apps could also be whitelisted. My question is -- is this idea possible to create? We would need admin preset controls to create the preset whitelist. We can't have stud

When I start a Simulator (iPhone 13 mini) with iOS 26 and activate Use the Same Keyboard Language as macOS, it still sets the keyboard to US (my Mac keyboard is in German). This makes the Mac keyboard unusable. It looks like a bug, because it clearly ignores the settings. When I type “@”, I get “¬”. Restarting the simulator did nothing, changing the settings back and forth also. BTW: Why does every single update of XCode come with a bug nowadays? I always have to spend half a day after an update to fix a problem I didn't have before. Highly frustrating.

Hi Apple Developer Community, I'm developing an eye-tracking application using ARKit's ARFaceTrackingConfiguration and ARFaceAnchor.blendShapes for gaze detection using Xcode. I'm experiencing several calibration and accuracy issues and would appreciate insights from the community. Current Implementation Using ARFaceAnchor.blendShapes (.eyeLookUpLeft, .eyeLookDownLeft, .eyeLookInLeft, .eyeLookOutLeft, etc.) Implementing custom sensitivity curves and smoothing algorithms Applying baseline correction and coordinate mapping Using quadratic regression for calibration point mapping Issues I'm Facing 1. Calibration Mismatch Red dot position doesn't align with where I'm actually looking Significant offset between intended gaze point and actual cursor position Calibration seems to drift or become inaccurate over time 2. Extreme Eye Movement Requirements Need to make exaggerated eye movements to reach screen edges/corners Natural eye movements don't translate to proportional cursor movement Difficulty reaching certain

After returning from the child view to the parent, the latter one will simply disappear. This is the full view. See itemsContent where I perform the navigation. The last tapped rectangle in this example will simply disappear. struct DashboardView: View { @State var viewModel: DahsboardViewModel @Namespace private var namespace var body: some View { ScrollView(.vertical) { LazyVStack(spacing: 24) { ForEach(viewModel.sections) { section in VStack(spacing: 16) { Text(section.title) itemsContent(for: section) } } } } } func itemsContent(for section: DashboardSection) -> some View { ForEach(section.items) { item in NavigationLink { PatternLearningRouter().rootView .id(item.id) .navigationTransition(.zoom(sourceID: item.id, in: namespace)) } label: { Rectangle() .fill(Color.yellow) .frame(width: 80, height: 80) .overlay { Text(item.title) } .matchedTransitionSource(id: item.id, in: namespace) } } } } XCode26 26.0.1(17A400) iPhone 16 Pro, iOS 26.0.1 Note: Only reproduced when I swipe ba

The following C code shows different results when build in debug or release mode with Xcode 26.0.1. #include static void print_fval(int16_t *src) { float fval = (float)((((int32_t)*src) << 16) - (1 << 31)); printf(fval: %fn, fval); } int main(int argc, const char * argv[]) { int16_t i16[1] = { 0 }; print_fval(i16); return EXIT_SUCCESS; } In debug mode the output is: fval: -2147483648.000000. In release mode the output is: fval: 2147483648.00000. The 1 << 31 might be questionable but I would expect the same outcome in debug or release mode. The difference is in compiling with optimizations or not, compiler option -O0 vs any other optimization option. Would this be considered a compiler/optimizer bug? Older versions of Xcode (15.4 and earlier) do not have this problem.

Hi, I am trying to load files from the Apple Vision Pro's storage into a Unity App (using Apple visionOS XR Plugin and not PolySpatial package). So far, I've tried using UnitySimpleFileBrowser and UnityStandaloneFileBrowser (both aren't made for the Vision Pro and don't work there), and then implemented my own naive file browser that at least allows me to view directories (that I can see from the App Sandbox). This is of course very limited: Gray folders can't be accessed, the only 3 available ones don't contain anything where a user would put files through the Files app. I know that an app can request access to these Files & Folders: So my question is: Is there a way to request this access for a Unity-built app at the moment? If yes, what do I need to do? I've looked into the generated Xcode project's Capabilities, but did not find anything related to file access. Any help is appreciated!

I see in iPhone built-in apps that action sheets are presented as popovers without arrows over their originating views. Here is an example in Messages and Shortcuts apps. In WWDC 2025 session Build a UIKit app with the new design, the speaker explains that all you have to do is to configurate the popover like we do for iPad. Here is the relevant transcript: 14:33 ActionSheets on iPad are anchored to their source views. Starting in iOS 26, they behave the same on iPhone, appearing directly over the originating view. 14:46 On the alertController, make sure to set the sourceItem or the sourceView on popoverPresentationController, regardless of which device it’s displayed on. Assigning the source view automatically applies the new transitions to action sheets as well! Action sheets presented inline don’t have a cancel button because the cancel action is implicit by tapping anywhere else. If you don’t specify a source, the action sheet will be centered, and you will have a cancel button. iOS 26 p

Hi everyone, Since updating to Xcode 26, I’ve been running into an issue with the new ChatGPT integration inside Xcode. Even though I have an active ChatGPT Plus subscription (GPT-4 or GPT-5) and I’m signed in to my OpenAI account, Xcode doesn’t seem to recognize my paid plan. After reaching the free usage limit, I get the following message: “Over daily limit. ChatGPT in Xcode will be unavailable for up to 24 hours. For higher limits, sign in with a paid ChatGPT account or upgrade to ChatGPT Plus.” The issue is that I am already logged in with my ChatGPT Plus account, and everything works fine on the ChatGPT web app — but inside Xcode, it keeps treating me as a free user. Here’s what I’ve tried so far: • Signing out and back into ChatGPT from within Xcode • Restarting Xcode and macOS • Verifying that I’m logged in to ChatGPT in Safari • Updating both macOS and Xcode to the latest versions None of these steps have resolved the issue. It seems like Xcode isn’t syncing properly with OpenAI authentication, and th

Prerequisite: After the MDM APP issues the command, the camera on the phone is no longer visible (unusable). After upgrading to iOS 26.1, the isSourceTypeAvailable: UIImagePickerControlSourceTypeCamera method keeps returning true when the camera is unavailable. The isSourceTypeAvailable: UIImagePickerControlSourceTypeCamera method on iOS 26.0.1 is normal, returning false when the camera is unavailable and true when it is available.
