Hi , I am currently encountering issues while running a Titanium application using Xcode 16. I would like to request your guidance on resolving the following problems: When running the Titanium app on a real device, I receive the following warning in Xcode and the app does not proceed beyond this point and the app is crashing on launch. warning: (arm64) /Users/Library/Developer/Xcode/DerivedData/Procedures-hamsarmfbtnowbcdocpmydtuafnp/Build/Products/Debug-iphoneos/Procedures.app/Procedures empty dSYM file detected, dSYM was created with an executable with no debug info. Thank you

This is recipe I used to do. Create new project. eg. Storyboard, Objective-C Select Project, Go to Build Settings > Architectures Change "Build Active Architecture Only" to "NO". Build... Go to build directory and check with "lipo" command > lipo -info Products/Debug/my-test.app/Contents/MacOS/my-test Architecture in the fat file: Products/Debug/my-test.app/Contents/MacOS/my-test are: x86_64 arm64 This has been working for Sonoma. However, I followed the same procedure in Sequoia, (Sequoia 15.5 Xcode 16.2), it's showing arm64 only. Architecture in the fat file: Products/Debug/my-test.app/Contents/MacOS/my-test are: arm64 Does anyone have any idea how to build Intel compatible binary in Sequoia dev environment?

I'm trying to copy some files from the Finder on macOS 14 to several Simulator instances running iOS 16 and 17. When I right-click the file in the Finder, I can select Share > Simulator, then a share dialog pops up where I select the relevant Simulator and click on Send. According to this official help topic, the Files app should open allowing me to choose the destination, but instead nothing happens and the shared file is nothing to be seen. What's the issue?

Previously it was needed to attach XCode (16.3) to the AUHostingService. This does not show up in the list of attachable processes any more. Just attaching to Logic Pro skips all breakpoints. I am trying to debug output-configuration as Logic offers versions of our Plugin that employ mono outputs which we do not actually provide. Any hints how I can trace through the plug-ins init code??

I updated Xcode and MacOS recently and haven't been able to compile my Flutter app on iOS devices/simulators since then. The error keeps changing every time I run it but here's one of the output in the terminal after running flutter run: Uncategorized (Xcode): Command SwiftGeneratePch emitted errors but did not return a nonzero exit code to indicate failure Error (Xcode): no such file or directory: '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/Session.modulevalidation' Error (Xcode): stat cache file '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/SDKStatCaches.noindex/iphonesimulator18.0-22A3362- db63dc9361471f152f572502bdbfe70a.sdkstatcache' not found Error (Xcode): unable to rename temporary '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/3F9VRK3CXAUUD/UIKit-1KHQ7M05IF VXC-56601391.pcm.tmp' to output file '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/3F9VRK3CXAUUD/UIKit-1KHQ7M05IF VXC.pcm': 'No such file or directory' Error (Xcode): could not build module 'UIKit' /Users/chiragbhansali/Chirag/Coding/Projects/app/test/build/ios/Debug-iphonesimulator/Flutter.framewo rk/Headers/FlutterAppDelegate.h:7:8 Error (Xcode): could not build module 'Flutter' /Users/chiragbhansali/Chirag/Coding/Projects/app/test/ios/Runner/GeneratedPluginRegistrant.h:9:8 Error (Xcode): failed to emit precompiled header '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/Runner-eifcguceazlwumgsyzegclqdrbqt/Build/Intermed iates.noindex/PrecompiledHeaders/Runner-Bridging-Header-swift_PB6A5GFLTNPC-clang_3F9VRK3CXAUUD.pch' for bridging header '/Users/chiragbhansali/Chirag/Coding/Projects/app/test/ios/Runner/Runner-Bridging-Header.h' Uncategorized (Xcode): Command PrecompileSwiftBridgingHeader emitted errors but did not return a nonzero exit code to indicate failure Uncategorized (Xcode): Command SwiftEmitModule failed with a nonzero exit code Uncategorized (Xcode): Command SwiftCompile failed with a nonzero exit code Could not build the application for the simulator.

Hi everyone, We're developing an AR app using Unity with Vuforia for object detection. Our app works well in full-screen mode, including detection and post-detection phases. However, we're facing a specific issue in iPad Split View multitasking mode. Problem: The AR camera (Vuforia-based) freezes during object detection if another app is opened in Split View. Post-detection, everything works fine in Split View. The problem only occurs during detection. Testing Environment: iPadOS 16+ Unity with Vuforia plugin Using EnableMultitaskingCameraAccess() method with AVFoundation to support camera multitasking AR scene is set up properly with detection capabilities in full-screen

I am having issues loading my model from a Swift Package with the following structure: | Package.swift | Sources | - | SamplePackage | - | - Core | - | - | - SamplePackageDataStack.swift | - | - | - DataModel.xcdatamodeld | - | - | - | - Model.xcdatamodel ( <- is this new? ) As mentioned, I am not required to list the xcdatamodeld as a resource in my Package manifest.

If I create a playground project that uses a JSONDecoder I get the following error. The LLDB RPC Server has crashed. The crash log is located at ~/Library/Logs/DiagnosticReports and has a prefix 'lldb-rpc-server'. Please file a bug and attach the most recent crash log. I have raised feedback for this, FB17702087, but I hope that there may be a workaround. The code I am using to try and get this to work is from The Apple Developer Documentation - JSON Decoder var greeting = "JSON Test 3" struct GroceryProduct: Codable { var name: String var points: Int var description: String? } let json = """ { "name": "Durian", "points": 600, "description": "A fruit with a distinctive scent." } """.data(using: .utf8)! let decoder = JSONDecoder() let product = try decoder.decode(GroceryProduct.self, from: json) print(product.name) // Prints "Durian" A screenshot of the playground showing the error The crash log (the file type has been changed to txt as ips file types cannot be selected for upload. lldb-rpc-server-2025-05-28-140832.txt

We've encountered a critical issue with the new linker of CLT16 (version 16.1.0.0.1.1729049160) that prevents proper initialization of BLOCK DATA. BLOCK DATA are used to initialize global variables in our Fortran code, and its failure to initialize those variables leads to a program crash. This affects our community of more that thousand scientists worldwide. The current workaround is using the -ld_classic linker option. However, this option is deprecated and will be removed in a future release, as described in the Xcode release note. I've attached a minimal example that reproduces the problem using GNU gfortran with the following instructions (the attached main.f.txt and bd.f.txt need to be rename to main.f and bd.f, respectively): gfortran -c bd.f gfortran -c main.f ar rv libtest.a bd.o main.o gfortran -ld_classic -o good.x -L. libtest.a gfortran -o bad.x -L. libtest.a Running the two programs, one can see that the BLOCK DATA are not initialised without the option ld_classic, $ > ./good.x 3.7273802569289098 2.8083922366048202 $ > ./bad.x 0.0000000000000000 0.0000000000000000 We kindly request your attention to this matter and a prompt solution or alternative workaround.

Hi, I am currently working on a MacOS App, where I need the undistortion function of opencv. But after I tried to add opencv to my project, I get following error: unexpected service error: The Xcode build system has crashed. Build again to continue. Cleaning the build folder also doesn't help. Does anyone have an idea what could be the issue? Ryan

I'm trying to write performance tests with Xcode 15, but it's not working: even though setting a baseline seems to work (baseline data files are created), Xcode seems to ignore that baseline altogether whenever the test is run. As a result, performance tests never fail, no matter how bad performance gets. The source editor persistently displays a “No baseline average for Time” message. Has anyone else encountered this? Figured out how to sidestep the issue? Of note, the issue is easily reproduced: create a new (macOS in my case) app project with tests, add a dummy performance test; run the test once and save its baseline, and despite this subsequent tests will always succeed, even if you significantly slow the dummy test down. (I've filed this as FB13330139)

Hello, FWIW I've been developing enterprise iOS apps going on 10 years and haven't seen a bug like this. It's a major blocker. Any advice is welcome. Pulled latest from my team's repository . I ran into a build issue. Reinstalled cocoa pods, resolved swift packages, cleared cache, and then tried to update my iOS simulators... Since then, everything is bricked. Can't side load an app or download a simulator. When I try to download simulator, as suggested by Xcode, I receive the following error: Registering simulator runtime with CoreSimulator failed.

I've cleared caches. I cleared project builds and all old simulators. I've reverted to much older previous commits after trying above just in case (even though I've verified no one else on my team is experiencing this issue). Nothing works.

When renaming A.value, it also causes the value inside the conditional compilation in checkRename to be renamed. How to resolve or avoid this situation? class A { let value = "1" } class B { var value = 0 } func checkRename() { var b = B() #if os(iOS) b.value = 456 #elseif os(macOS) b.value = 789 #endif } Xcode Version 15.4 (15F31d).

I have been working for a while now. Never encountered this issue. After accepting the invite from the organization. The organizations does not appear at developer apple account. But can see the organization at app store connect. Yes i have checked the account permissions. I have the admin role and developer role etc is checked everything is correct. This is not just me happening with my colleague as well.

I just want to rant why is Xcode such a bad ide and I wish Apple can do a better job on Xcode. Here's why: The preview is so slow. Most of the times it's just faster for me to test on a real device. It is so slow, and many times I need to force quite after it's being unresponsive for sometimes. When I'm working on larger projects, the loading time becomes extremely slow especially when there's other clients that might be reading the same files like a Git client or simply iCloud. The breakpoint is so slow. I don't know why, is it an iOS thing? But when I'm on ASP.Net the breakpoints are super fast. For Xcode it takes a long time to pause and show data. It's so big I don't know why it is so hard for Apple to make their ide better. The community has been unsatisfied with Xcode for a long time. There's many tricks on the internet that you can find to help you resolve some issues with your project that's actually related to Xcode. Instead of using these tricks, Apple should just fix these issues. Learn from Intellij!

I'm running a macOS 15.2 guest on a macOS 15.1.1 host with UTM. I'm trying to install Xcode from within the App Store but cannot login to the App Store. When I enter credentials and click 'Sign In' I get the Error 'An unknown error occurred'.

On my M4 Mac running macOS 15.5 using Xcode 16.4 & Xcode CLT 16.4, Swift code in my Swift Package Manager 5.9 project (https://github.com/mas-cli/mas) builds fine against some included Objective-C headers via the following command line: swift build -c release But cannot find modules for the included Objective-C headers when building inside Xcode 16.4 or with the following command line on the same Mac: xcodebuild -scheme mas -configuration Release -destination platform=macOS,arch=arm64,variant=macos The error is: Sources/mas/AppStore/AppleAccount.swift:9:16: error: no such module 'StoreFoundation' How can I get Xcode / xcodebuild to work? Note that the project is normally built by running: Scripts/build which runs: swift build -c release after running the following script, which must be run before any build (swift, Xcode, or xcodebuild) because it generates a necessary file (Sources/mas/Package.swift): Scripts/generate_package_swift I've tried moving the Objective-C headers into include subfolders of their existing module folders, using double quotes instead of angle brackets for the #import statements, having module.modulemap files in the include subfolders or their parent module folder, and moving the module folders one level up the file hierarchy, to no avail. I've also tried various changes to the root-level Package.swift (not the generated one deeper in the hierarchy, which isn't inclined in the build configuration), like making separate library targets for each of the Objective-C modules, various swiftSettings & linkerSettings, etc. Maybe some of those changes would have helped, but maybe they were in incorrect combinations. Thanks for any help.

We got an app for iPad which has two targets one for the App itself (MainApp target ) and another one for the Driver ( Driver Target ) using DriverKit. The app works fine in Development, but I'm trying to distribute it with adhoc. I've requested the Distribution Entitlement to Apple, after getting it, the App Id for the Driver has the following Capabilities: DriverKit, DriverKit (development), DriverKit USB Transport (development), DriverKit USB Transport - VendorID, In-App Purchase Now in the profile section, I've created a adhoc profile for the Driver AppId (Identifier). Obviously I've also created an Adhoc profile for the Main AppId Finally in the Signing & Capabilities Section I set up the profiles for MainApp target, int the Debug one I set up the Development one and int the Release one I set up the adhoc one. I do the same in the Driver Target, but when I set up the Adhoc one in the Release, I've got a warning: Xcode 14 and later requires a DriverKit development profile enabled for iOS and macOS. Visit the developer website to create or download a DriverKit profile Also interestingly the Signing Certificate section says: None I also set up the Capabilities for the Driver Target: DriverKit USB Transport - VendorID DriverKit USB Transport ( Development ) Inside these capabilities I set up the vendor ID as dictionary The problem is, if I try to Archive the app I will get the previous Warning message as error: Xcode 14 and later requires a DriverKit development profile enabled for iOS and macOS. Visit the developer website to create or download a DriverKit profile. Any idea what I'm missing? Thanks
