Reply to Blender Geometry Nodes to Reality Composer Pro
Hello @SteveTalkowski ! Thank you for your question. The root cause of your issue is a bit technical so I hope you'll bear with me. You're seeing an issue related to the different ways USD can be rendered on your system. Different renderers support different feature sets of the USD spec and unfortunately RealityKit's USD renderer does not support vertex animation. In some contexts, macOS will display USD files using a renderer called Storm (you can search online for Hydra Storm), and this is not the same renderer used by Xcode or your app, which uses RealityKit to render USD. Because Storm supports vertex animation while RealityKit does not, you'll see your animation playing in some contexts and not others, and you won't be able to use this particular type of animation in a RealityKit app. This is confusing, but hopefully the link above helps explain everything. You've authored your asset correctly! Unfortunately, RealityKit does not support this particular type of animation. I recommend sending us f

Source item disappears after swipe-back with .navigationTransition(.zoom)
[Submitted as FB21078443] When using .matchedTransitionSource with .navigationTransition(.zoom), swiping back from the left edge to return from a detail view causes the source item to disappear once the transition finishes. It’s only a visual issue—the item is still there and can be tapped to open again. This doesn’t happen when using the Back button; only the swipe-back gesture triggers it. Also, it only reproduces on a physical device, not in Simulator. SYSTEM INFO Xcode 26.1.1 (17B100) macOS 26.1 (25B78) iOS 26.1 (23B85) iOS 26.2 (23C5044b) REPRO STEPS Run the code below on a physical device, tap an image, then swipe from the left edge to dismiss the detail view. ACTUAL The image zooms back to its origin, then disappears once the animation settles. EXPECTED The image card remains visible.

Reply to Apple-hosted managed asset pack not found on macOS
It appears to be correctly signed. Automatically manage signing is checked, my standard team is set. With those settings, as soon as I assign an app group in Xcode 26.1, it changes to an Xcode managed provisioning profile and my valid Apple Development certificate and does not let me change them. I also checked the build with codesign -dv --verbose=4 and in ~/Library/Developer/Xcode/UserData/Provisioning Profiles to verify and that the profiles update, e.g., when I change the Info.plist. I also tried setting up a fresh sample project from the standard multiplatform SwiftUI app template in Xcode and did not change anything in Signing & Capabilities except setting the app group for the app and download extension. Same minimal app just calling AssetPackManager.shared.assetPack(withID:), same result: on iOS it works, on macOS the URL override is not permitted.

Apple Watch stuck on "Copying shared cache symbols" – blocks real-time testing via Xcode
Hi everyone, I’m a student developer currently building a watchOS app that uses HealthKit and HKWorkoutSession to estimate core body temperature from real-time heart rate data. The app runs well in the simulator, but testing on a physical Apple Watch has been extremely difficult. Each time I try to run the app from Xcode (Version 16.3), the build gets stuck on: “Copying shared cache symbols from MyWatchName (0% completed)” Sometimes it just stops stating connection failure. However, more often no errors are shown, but the sync never finishes. I’ve tried the following without success: Restarting the watch, iPhone, and Xcode Switching networks (Wi-Fi and hotspot) USB wired pairing Resetting developer settings and trust prompts Deleting derived data Rebuilding the project This is especially limiting for a real-time health tracking app where I need to monitor HKLiveWorkoutBuilder data while the screen sleeps — which can’t be tested effectively in the simulator.

Reply to Live Activity Shows Only Black Dynamic Island UI (No Content Rendering) — Widget Extension Receives Updates but SwiftUI UI Is Empty
Thanks for your post. Although you have a comprehensive list of questions, such as tint handling without demonstrating the setup process, it appears that you are using Flutter instead of Xcode. I recommend starting with a tutorial on LiveActivity and configuring it to observe its functionality and the rendering of the Activity UI. This step-by-step approach ensures that you have a thorough understanding of the process and can identify any potential issues. Even thought assumes you are using Xcode. https://developer.apple.com/documentation/activitykit/displaying-live-data-with-live-activities Also I would recommend to go to the 3rd party tool support channel and see if they have a sample or a tutorial to go over the issues. You should check with the support resources provided by the 3rd party to get assistance with their software. Unless another developer in the forums has experience with the third-party and can provide assistance. Albert Pascual

Apple terminated my account without even validating their "Evidence"
I truly believe Apple doesn't care about false positives when terminating developer accounts. They keep the doors closed and appeal is futile. Background I'm an independent mobile game developer for 5+ years. I share my games on social media and get organic users, so everything is transparent. My latest game is a relaxing ball game. It has tap mechanics and players should tap when a ball hits to a xylophone-like bars. In addition, game had level editor feature that players can create their levels, publish and create their videos and share on social media (like geometry dash) A publisher approached me and proposed me to publish my game on their account. I said ok, because I don't have any budget and operational resource. A few months after, Apple terminated publisher's account without telling any specific reason. They said fraud. After 15 days, I got account termination message: Evidence of Dishonest or Fraudulent Activity Your account is associated with terminated developer accounts and/or accounts engaged in

Reply to AlarmKit and power button.
Thanks for the post. It is intriguing to note that you are utilizing the AlarmManager property alarmUpdates. Could you please provide the Xcode version you are currently using? Although I have not personally utilized this property, as described in the documentation, it allows you to receive notifications when an alarm alerts, snoozes, or dismisses. Therefore, it is possible to retrieve updates at AlarmManager.shared.alarmUpdates. Could you kindly share a focused sample project that demonstrates the issue you are encountering with obtaining these updates? I recommend referring to the sample provided in the documentation: https://developer.apple.com/documentation/alarmkit/alarmmanager/alarmupdates-swift.property About the focused project: If you're not familiar with preparing a test project, take a look at Creating a test project.

Reply to Xcode and Reading documents from a URL connection.
I do use URLsession. From what I could find with research online and even checking with ChatGPT for more specific questions on the topics that seemed to be what I needed to allow the app to connect to a website and use URL links to download docx files for the app. The problem that I am seeing is I am not sure if I am using the URLsession correctly or if there are additional steps I need to take when it comes to accessing this Documents Directory that is on the mobile device itself to access the documents. From my own testing when Io run the app I try checking documents on the mobile device but nothing looks to update so my guess is I am not using the URLsession function correctly. I am a beginner still with using swift and Xcode so I am trying to learn as much as I can for working on this project. My Project is setup with multiple .view scripts to handle different parts of the app itself. They are setup as follows: ContentView This script is used for viewing the app itself where I have buttons displa

Reply to Apple-hosted managed asset pack not found on macOS
Ah, that’s helpful information. We log the message about not permitting development overrides when the app isn’t signed with a development profile. Can you confirm that your app is code-signed for development with a valid provisioning profile when you run it from Xcode? In particular, ensure that it isn’t ad-hoc-signed (i.e., “sign to run locally”).

Reply to Can an independent watchOS app be listed under the same iOS app store title of an IOS app?
Yeah, when you create an independent watchOS app and an iOS companion app (see TN3157 for the terminology), the watchOS app will be embedded into the iOS app bundle and be code-signed together. Unless you figure out a way to create the iOS app bundle and make sure it has the right structure, content, and code signature, you will need to put the two targets in one project and let Xcode do all that.

Creating an URL bookmark in macOS 26.1 of a Windows NTFS fileshare returns a bookmark with access to the local drive
Since macOS 26.1, creating bookmark data based on a NSOpenPanel URL, does not return the expected bookmark data when the selected source concerns a Windows NTFS fileshare. When the returned data is being resolved, the returned URL points to the local drive of the current Mac. Which is of course super confusing for the user. This issue did not occur in macOS 26.0 and older. In essence, the following code line with 'url' based on an URL from a NSOpenPanel after selecting the root of a Windows NTFS share, creates an incorrect bookmark in macOS 26.1: let bookmark = try url.bookmarkData(options: .withSecurityScope, includingResourceValuesForKeys: nil, relativeTo: nil) I have tested this on two different Macs with macOS 26.1 with two different Windows PC both hosting NTFS files shares via SMB. My questions: Have anyone else encountered this issue in macOS 26? Perhaps even with other fileshare types? Is there a workaround or some new project configuration needed in Xcode to get this working?

Reply to LLDB and environment variables in Xcode
Xcode doesn't pass these environment variables to lldb when it runs it, nor does it preprocess the .lldbinit files to insert these variables. We don't pass them to lldb as there's too much chance one of them really wouldn't be appropriate for lldb and cause hard to diagnose problems. And since .lldbinit files can contain arbitrary user expressions, preprocessing can also cause problems. Instead, the suggested way to do this is to make a target specific lldbinit file - as you have done - and in that file bring in all the .py files you need using command script import --relative-to-command-file ./my_python_files/my_python_file.py That allows you to give the paths to all your python files relative to the target-specific .lldbinit file without having to know where any of them actually are. Note, the same option exists for sourcing other files of lldb commands using command source.
