I have been working on a project before this year's new OSX and Xcode update and I was able to build the project with little trouble. But since updating to any of the beta software, including the latest version of Tahoe 26.0 and Xcode26-beta4 I have not been able to build this same project. I have tried reseting package cache and updating to the latest package versions. As well I have deleted the derived data and cleaning the build folder. The following error output is one of 55 errors I am getting. It seems like the modules for the XRSimulator are redefinitions from those for MacOSX. I don't know how to limit or redirect the definition of the modules to just those for the XRSimulator (this is a VisionOS project). I also tried all of this on different betas of Xcode with all the same result. This bug is causing a problem with the 16.4 version of Xcode as well. I would really really appreciate anybody's help on this. in file included from /Applications/Xcode.app/Contents/Developer/Pl

Hi All, I'm new to IOS development/Xcode and would appreciate any/all advice/guidance on this unexplainable issue. Please excuse my potential usage of wrong terms. I have a project that was handed to me in a near completed state and there is a UI bug in the program that I am trying to fix. It is opening multiple instances of a View Controller Scene in the wrong dimensions, causing instanced layers that act independently of each other rather than a simple page re-routing like regular front end development. Upon investigating the codebase I have noticed the following potential source: The storyboard was originally modeled after an IPhone 16 Pro Max, however the main device we will be creating the app for is an iPad 11 mini. Upon changing the simulated device, the view models for most of my XXXViewControllerScenes are not rendering the correct size. Here are some examples: Image1 ) When selecting the RootNavController (scene 1) > all storyboard scenes render the correct size (at least thats what it v

It seems that beta 3 broke StoreKit Testing when running against an iOS 26 simulator device. Specifically, when validating product IDs, the debug console displays messages like the following: [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for:

When navigationTransition returns through the return gesture, the original view disappears。 The same problem occurs when using the official example。 https://developer.apple.com/documentation/swiftui/enhancing-your-app-content-with-tab-navigation xcode Version 16.4 (16F6) macOS 15.5

We developing Native App with C++17 for iOS. We override global new and delete operators. This App deallocate all allocated memories correctly by Run on Xcode (Command + R), but exception occurs launch from xcrun or App icon on iPhone. I debugged the exception. Overriding new operation was called correctly, but overriding delete operation was not called. The default delete was called. I'm not sure why is that. STEPS TO REPRODUCE Build xcode project. Run xcrun devicectl device install app --device Run xcrun devicectl device process launch --console --device PLATFORM AND VERSION iOS Development environment: Xcode 16.4, macOS macOS Sequoia 15.5 Run-time configuration: iOS 18.5 main.cpp I attached is sample code to reproduce this problem. main.cpp

FB18383742 Setup 🛠️ Xcode 16.4 (16F6) 📱 iPhone 13 mini (iOS 18.0.1) ⌚️ Apple Watch Series 10 (watchOS 11.3.1) Observations As AccessorySetupKit does not request Core Bluetooth permissions, when a watchOS companion app is installed after having installed the iOS app, the toggle in the watch settings for Privacy & Security > Bluetooth is turned off and disabled After removing the iPhone associated with the Apple Watch, Bluetooth works as expected in the watchOS app Upon reinstalling the iOS app, there's a toggle for Bluetooth in the iOS ASK app's settings and the ASK picker cannot be presented 🤨 From ASK Documentation: AccessorySetupKit is available for iOS and iPadOS. The accessory’s Bluetooth permission doesn’t sync to a companion watchOS app. But this doesn't address not being able to use Core Bluetooth in a watch companion app at all 🥲 Reproducing the bug Install the iOS + watchOS apps Launch iOS app, tap start scan, observe devices can be discovered (project is set up to find heart rate

Hi, I’m seeing a crash when running my app on iOS 18 simulators or devices using Xcode 26 beta 3. My app’s minimum deployment target is iOS 17, and the crash does not happen when running from Xcode 16.4. The crash occurs specifically at this line: return UIStoryboard(name: storyboard.rawValue, bundle: nil) .instantiateViewController(withIdentifier: view.rawValue) Crash Details: ** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named _TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView_ because no class named _TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView_ was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)' *** First throw call stack: (0x191c3321c 0x18f0cdabc 0x191c91ea0 0x19d740774 0x19d740a18 0x19d740cac 0x194626680 0x194dbc784 0x19d740890 0x19d740cac 0x1949aadd8 0x19d740890 0x19d740a18 0x19d740cac 0x19480

I'm trying to run sample Trails app from the documentation, unaltered. When I do the build, I get a Command ValidateAppShortcutStringsMetadata failed with a nonzero exit code error. How do I debug this? I'm trying this on Xcode 16.4.
