Area: visionOS 26.4 · AVFoundation · AVCapture · External/UVC video Classification: Suggestion / API Enhancement Request (also: Incorrect/Missing Documentation) Device / OS: Apple Vision Pro, visionOS 26.x. Xcode 26.4.1, XROS26.4.sdk. Summary On visionOS, a third-party app cannot display two UVC USB cameras (connected through a powered USB-C hub) at the same time. Every AVFoundation path that would enable this on iPadOS is either unavailable or fails at runtime on visionOS, and there is no public non-AVFoundation fallback (no IOUSBHost, no DriverKit, no usable CoreMediaIO, no MFi path for generic UVC devices). This is a real capability gap relative to iPadOS and macOS, and Camo Studio on iPadOS (App Store ID 6450313385) demonstrates the two-camera USB-hub use case is legitimate and valuable for spatial-video/hybrid-capture workflows on Vision Pro. Steps to reproduce Connect a powered USB-C hub to Apple Vision Pro with two UVC webcams attached. Build a visionOS app that uses AVCaptureDevice.D

Pulling my hair out here. After upgrading to Xcode Version 26.4.1 (17E202) I've started getting unable to create tasks to copy stub binary: can't determine architectures of binary: /Applications/Xcode.app/Contents/Developer/Platforms/WatchSimulator.platform/Library/Application Support/MessagesApplicationStub/MessagesApplicationStub: Cannot open file handle for file at path: /Applications/Xcode.app/Contents/Developer/Platforms/WatchSimulator.platform/Library/Application Support/MessagesApplicationStub/MessagesApplicationStub: The file “MessagesApplicationStub” doesn’t exist. No matter what I do when trying to run the build (worked in previous versions). I've tried fresh install from App Store, direct package download, removing the SDKs, even previous versions and no matter what I get

Hello everyone. I need help! I'm using Xcode solely to create an archive of a mobile application created with WinDev Mobile. When everything is working correctly, I simply retrieve the application's generated version from WinDev Mobile, launch the archive creation process, and add a new version to TestFlight! Then I can test the application on the iPhone. The current problem is that the application crashes, without any error message, in a specific use case. Hoping to get some help with this crash, I had the idea to test the application using Xcode. Once launched, a crash occurs if I follow the same process. There's an error message, which I'll paste below. What does this error mean? How can I relate it to my WinDev Mobile code? Have a good day.

I am running Tahoe 26.4.1 on a MacBook Air, M4, 2025. In System Settings, I have an item heading of Software Update Available. Clicking on that brings up Command Line Tools for Xcode 26.4. The only available choices are to Update Now or Cancel. In the past, I was developing a game, but have quit working on that, and deleted Xcode and Command Line Tools. Wanting the Command Line Tools ... line to disappear from System Settings, I called Apple Support, and at their request have followed the steps in https://developer.apple.com/documentation/xcode/installing-the-command-line-tools to delete this entry in System Settings, namely the 2 sudo's in that article under the section Uninstall the command line tools. This did not cause the Command Line Tools for Xcode 26.4 line in System Settings to disappear (as I was told by Apple support that it would, because I would be deleting the receipt). In Terminal, I did indeed receive a response of No receipt for 'com.apple.dt.commandlinetoo

Hello, I'm experiencing a navigation bar positioning issue with my UIKit iPad app on iPadOS 26 (23A340) using Xcode 26 (17A321). The navigation bar positions under the status bar initially, and after orientation changes to landscape, it positions incorrectly below its expected location. This occurs on both real device (iPad mini A17 Pro) and simulator. My app uses UIKit + Storyboard with a Root Navigation Controller. A stack overflow post has reproduce the bug event if it's not in the same configuration: https://stackoverflow.com/questions/79752945/xcode-26-beta-6-ipados-26-statusbar-overlaps-with-navigationbar-after-presen I have checked all safe areas and tried changing some constraints, but nothing works. Have you encountered this bug before, or do you need additional information to investigate this issue?

I'm converting my game from SceneKit to RealityKit. It has a SpriteKit overlay that according to Explore advanced rendering with RealityKit 2 I can add with the code below. The code runs fine if the SKScene only contains a SKSpriteNode (see the commented out line), but when I add a SKShapeNode with a fillColor instead, the app crashes with this error: -[MTLDebugRenderCommandEncoder validateCommonDrawErrors:]:5970: failed assertion `Draw Errors Validation MTLDepthStencilDescriptor uses frontFaceStencil but MTLRenderPassDescriptor has a nil stencilAttachment texture MTLDepthStencilDescriptor uses backFaceStencil but MTLRenderPassDescriptor has a nil stencilAttachment texture ' I don't know enough about low-level graphics and stencils yet to figure out a quick solution, so I would appreciate if anyone could share an easy fix or explanation of what's wrong. Thanks! class ViewController: NSViewController { var device: MTLDevice! var renderer: SKRenderer! override func loadView() { let arView = AR

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...

My Claude Agent component version was 2.1.81, it prompted me for an update the other day from the original release version 2.1.59. But now that I've installed Xcode 26.4.1 it's back to thinking 2.1.59 is the newest version. With every Xcode release it feels like there's a new regression or weird surprise with coding intelligence (26.4 was Claude losing its OAuth token every 8 hours or so). It really feels like this stuff needs more eyes on it. Filed as FB22529202

I have an iOS project based on SwiftUI in which almost all code is organised in Packages. With Xcode 26.2 and 26.3, I can preview all SwiftUI views without issues. With Xcode 26.4, the same previews don't work, in the canvas appears this error message: Cannot preview in this file. Could not find target description for “TaskListView.swift”. The explanation is: The list of source files that produce object files did not contain this file to be previewed. Check to make sure it is not excluded using the EXCLUDED_SOURCE_FILE_NAMES build setting. If I add a SwiftUI view to the main project files (not in a package), the preview works as expected. Is it an Xcode 26.4 regression? Or do I need to modify some configuration file?
