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.

Sorry if this is a dumb question. I’m still a beginner. I created an Xcode Playground app with Microphone and Speech Recognition capabilities enabled, along with a backup Info.plist. However, when running the app on Mac Catalyst, a real device, or the iOS and iPadOS simulators, it crashes right after the Speech Recognition permission popup and again after the Microphone permission popup. For extra context, the app initially worked fine in the Swift Playgrounds app, but that environment uses an outdated SDK, so it no longer supports some of the features I’ve implemented. I’m also struggling to find clear, beginner-friendly documentation that explains how AVAudioEngine works, which is making it hard to understand what’s going wrong and how to debug it.

In the XCode 16 beta, it isn't possible to create a new StoreKit configuration file because the templates list doesn't contain that option. Adding the storekit extension to a file crashes XCode or doesn't have an effect at all. But, loading an existing file still works.

I'm working on a FileProvider which allows access to encrypted files in Dropbox; I can successfully read and present the decrypted files, so I know it's basically working. But I'm having problems getting FileProvider to re-enumerate a folder when its encryption status changes. When the FileProvider receives an update notification saying a folder is now encrypted, I use signalEnumerator to re-enumerate the folder: FileProviderExtension.manager?.signalEnumerator(for: existingItem.itemIdentifier, completionHandler: { (ourError : Error?) -> Void in       if let ourError = ourError {           log("notifyCallback: mount / unmount failed re-enumeration: \(ourError)")       } else {           log("notifyCallback: mount / unmount signalled re-enumeration; pending")       } }) The log reports that the re-enumeration is pending... but as far as I can tell, neither enumerateItems nor enumerateChanges is called on the folder's item unless a Finder window is actually open for that folder. This means that, when an app other than Finder tries to access the files through the filesystem, it doesn't see the updated set of filenames. (For further reference: I've added code to both enumerateItems and enumerateChanges, so that if the call has been triggered by a recent folder-encryption notification, it retrieves a complete set of items from the Dropbox folder. If a retrieved file has an encrypted filename, it reports it as a modified item and returns its filename in-clear; if the filename isn't encrypted, it doesn't return the item (for enumerateItems) or returns it as a deleted item (for enumerateChanges). This approach seems to work successfully for listing folders with a constant state; it's only if the user encrypts / decrypts a folder without currently having a Finder window open inside that folder that I'm not seeing a refresh.) Any advice on how I can force a re-enumeration without a Finder window currently being displayed?

Hi, I have a recurrent problem with an Xcode workspace that I cannot figure out how to solve: When I command-click a symbol (or press ctrl-cmd-J) to find its definition, and when that definition is in a header file belonging to a custom static library, Xcode opens a header located in the derivedData folder rather than in the project's source codes. The exact location of this file is not in the main 'Build' folder but rather in a folder that seems dedicated to indexing: derivedData/myProject/Index.noIndex/Build/Products/Debug/Include/theHeader.h Consequently the file opened by Xcode is uneditable, I have to close it and reopen the source using another method. Even when the correct header is already opened, and I try again, Xcode reopens the wrong file so that it's opened twice with different paths. In the config file of the main application project, I reference the sources of these static libraries like this: HEADER_SEARCH_PATHS = ${SRCROOT}/myLibrary1/Sources ${SRCROOT}/myLibrary2/Sources ${SRCROOT}/myLibrary3/Sources However, removing this doesn't fix the issue and I don't see any other related-settings. Any idea to fix this annoying issue would be greatly appreciated, thanks!

Hi; Here is a simple program that reads a file and counts number of 1s bits in it. The file it reads, simple.txt, is a static text file, resides in the file system, and nothing is touching it during the program execution. The file's length is 436 bytes. When the program is run in the terminal it produces consistent results. Each run counts 1329 1s bits. It behaves differently when run in Xcode. A simple command-line tool project having a single file. Running the program multiple times, via Command-R, produces something strange. That is each execution randomly produces one of two results. One is expected 1329 1s bits, another one shows 1333 1s bits. That is it counts four bits more. Again, each run randomly produces one of those two results. And it happens only when I run the program in Xcode. I tried a different sample text file and experienced the same behavior, but the difference in 1s bits count was five bits. Any idea of how this behavior can be explained? func countOnes(in byte: UInt8) -> Int { var nOnes = 0 var mask: UInt8 = 0x1 while mask != 0 { if (byte & mask) > 1 { nOnes += 1 } mask <<= 1 } return nOnes } func countOnes(in buffer: UnsafeMutableRawBufferPointer, length: Int) -> Int { var nOnes = 0 for byte in buffer[0...length] { nOnes += countOnes(in: byte) } return nOnes } var fd = try FileDescriptor.open("sample.txt", .readOnly) var buffer = UnsafeMutableRawBufferPointer.allocate(byteCount: 4096, alignment: 4) var nBytes = try fd.read(into: buffer) var nOnes = 0 while nBytes > 0 { nOnes += countOnes(in: buffer, length: nBytes) nBytes = try fd.read(into: buffer) } buffer.deallocate() try fd.close() print(nOnes) My machine Darwin MacBookPro 24.6.0 Darwin Kernel Version 24.6.0: Wed Oct 15 21:08:19 PDT 2025; root:xnu-11417.140.69.703.14~1/RELEASE_ARM64_T8103 arm64 macOS Sequoia 15.7.2 Xcode 26.1.1 (17B100) Thanks, Igor

I've been working on UI Tests for a month or two and things have been great. But I believe there was a recent update to Xcode [running Version 26.2 (17C52)] and since then about 80% of the time when I try to view the test results so I can see the screenshots and video, Xcode crashes hard and I have to open it again. I've tried cleaning the Build folder and Derived Data and all sorts of stuff like that. Restarted Xcode, restarted my computer, etc. Any idea of how I can avoid these crashes?

Hi, I'm interested in trying out Xcode Assist to help with things like complicated refactors or writing tests cases. The ChatGPT and Claude options both share your code with third parties, which is not acceptable for my use case. Has anyone used a fully local model for Xcode Assist? I see that you can select one in the Apple Intelligence section of Xcode's Preferences screen, but don't really know where to start. Are there local models that work well with Xcode Assist and that truly keep your source code private?

Hello, I’ve been experiencing a persistent issue in Xcode since version 26.0, and it is still present in 26.2. When using the split view to display two files side by side, the area in the top‑right corner of the window (the inspector / options panel) starts flickering continuously. This happens regardless of whether I’m using the light or dark theme, and even with the Liquid Glass effect disabled in macOS settings. None of these changes have any impact on the issue. I have already submitted a bug report through Xcode (Feedback Assistant), but the issue is still present as of today. The flickering makes the interface difficult to use and visually very distracting. I’ve attached a video to clearly show the issue. I will review the attachment at the time I publish this post. Thanks in advance for any help or feedback.

Our apps, such as iCMTGIS PRO, provides the ability for users to open a job file received as an email attachment. Our apps use application:openurl:option to get the URL for the job file (*.pmp). We use [URL path] to convert it to NSString format. Then we use fopen to read the .pmp job file in "read only" mode. On iPad Air (5th generation) running iOS Version 18.6.2, our apps are able to read the .pmp job file. However, on iPhone 11 running iOS: 26.2, using fopen to read the .pmp file, we get a NULL value and are not able to correctly read the .pmp file.

Apple made them both, and for some reason they are acting like each is speaking a foreign language. Once you plug the iPad in, shouldn't the "trust this computer" kick in and allow the iMac to turn on developer mode? I'm the dumbest person in the world when it comes to Code, but this is a no brainer! And the fact that the iPad is in Developer mode, is the most frustrating part. This needs a fix.

Out of nowhere I got some red banner on top of my iPhone 13 mini / iOS 17.5. I cannot pin point the root cause of this. What I can say is that it only happens to Simulators of a certain type, e.g. iPhone 12 and 13 mini, but not iPhone 14 for example. I have installed Xcode 26.1.0 and 26.1.1, out of which 26.1.0 is selected: $ xcode-select -p /Applications/Xcode-26.1.0.app/Contents/Developer And following runtimes: $ xcrun simctl runtime list == Disk Images == -- iOS -- iOS 17.5 (21F79) - CF933623-A258-44F8-B248-C0F25C0C343B (Ready) iOS 26.1 (23B80) - D11C3CDC-EE3D-44CC-8B92-9B7D00B54B0B (Ready) Total Disk Images: 2 (14.6G) Installing the newer 26.1 23B86 runtime doesn't help either.

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...

Xcode 26.2 RC has been out for over 24 hours and it's still not possible to submit apps.

Has anyone been able to use Google Gemini with Intelligence in Xcode? I got the Claude models working in there but as much as I try I can't see any Gemini models.

Hey all, I recently updated to Xcode 26.2 and I'm having the hardest time trying to download the corresponding iOS simulator. I installed Xcode from developer downloads and the app did not come loaded with an iOS simulator. When trying to download from Components in Settings, I only get the following message: Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 User Info: { checkConfiguration = 1; } I also tried downloading via Terminal but also get a download failed message. I am on the latest macOS and have over 600 GB of disk space available. In previous versions, I was able to download the iOS simulator directly from Developer Downloads, but anything after 26 is not there. Any suggestions?

Gitlab runner on M4 Mac Mini 2024, XCode 26.2, supported platforms: iOS, native UIKit swift project. Cocoapods. Trying to run tests via fastlane: run_tests(workspace: 'Project.xcworkspace', destination: "platform=macOS,id=#{deviceId}", scheme: "Release", clean: true) And having an error: $ xcodebuild -showBuildSettings -workspace Project.xcworkspace -scheme Release -destination platform\=macOS,id\=01234567-0123456789B9001C 2>&1 [12:23:53]: Could not read the "SUPPORTED_PLATFORMS" build setting, assuming that the project supports iOS only. [12:23:54]: Found simulator "iPhone 16 Pro (18.5)" The tests runs just fine in xcode on "My Mac (Designed for iPad)" device on the very same machine. Compared the output of xcodebuild -showdestinations in terminal: $ xcodebuild -showdestinations -workspace Project.xcworkspace -scheme Release Available destinations for the "Release" scheme: { platform:macOS, arch:arm64, variant:Designed for [iPad,iPhone], id:01234567-0123456789B9001C, name:My Mac } { platform:iOS, id:dvtdevice-DVTiPhonePlaceholder-iphoneos:placeholder, name:Any iOS Device } { platform:iOS Simulator, id:dvtdevice-DVTiOSDeviceSimulatorPlaceholder-iphonesimulator:placeholder, name:Any iOS Simulator Device } { platform:iOS Simulator, arch:arm64, id:A7E98A79-B29B-4E9A-8103-ECBA55ABC0C6, OS:26.2, name:iPhone 17 Pro } But when I launch this command in gitlab runner, I get this: Available destinations for the "Release" scheme: { platform:iOS, id:dvtdevice-DVTiPhonePlaceholder-iphoneos:placeholder, name:Any iOS Device } { platform:iOS Simulator, id:dvtdevice-DVTiOSDeviceSimulatorPlaceholder-iphonesimulator:placeholder, name:Any iOS Simulator Device } { platform:iOS Simulator, arch:arm64, id:A7E98A79-B29B-4E9A-8103-ECBA55ABC0C6, OS:26.2, name:iPhone 17 Pro } I suspect gitlab runner to ruin some ENV variable, probably. So I googled the most common issues on the internet and tried everything I found: LANG: "en_US.UTF-8" LC_ALL: "en_US.UTF-8" unset CFProcessPath And none is worked. I also compared the printenv output in terminal and gitlab runner, didn't found anything suspicious. Ran out of ideas. How can I troubleshoot this?

The profile expiration date is approaching, and no amount of inquiries will solve it. Create a new profile Download a new profile from Xcode Press archive, press Distribute App, press Enterprise, and distribute Invalid expiration date in profile of summary of review app.ipa content I've tried everything that comes out by Googleing profiles, such as regenerating profiles, erasing caches, updating Xcode, updating macOS, deleting existing profile information, etc. Expiration date different from the expiration date of the profile created in that menu is displayed. The expiration date of the profile I created is December 8, 2026, and the previous certificate is January 22, 2026. However, the profile information of the generated ipa is February 12, 2026. So I can't distribute this app because I'm scared, and the expiration date is coming up. Users should have a period of time to update. Get me a novice developer who's choking up.

The Send to Device in Reality Composer Pro no longer works for me. The progress spinner keeps spinning... Happens with Wifi and Developer Strap (first gen). Any known workarounds / ways to recover?
