Hi, today I upgraded Xcode to Version 16.4 (16F6) and the Simulator to version Version 16.0 (1042.1) since then I get the following message in the debugger with any project when running the simulator: load_eligibility_plist: Failed to open /Users/xxxx/Library/Developer/CoreSimulator/Devices/1B9FA609-7502-42DE-93A8-B856E2618A7F/data/Containers/Data/Application/4FA1B071-A5F1-4E00-B3AC-630E273DD900/private/var/db/eligibilityd/eligibility.plist: No such file or directory I have checked other similar questions but in my case I do not have Cocoapods installed.

Hello, I'm trying to use devicectl to observe Darwin Notifications on my iPhone. Instructions: OVERVIEW: Observe a Darwin notification on a device. Note that this command will wait for 300 seconds by default before exiting. You can override this by providing a different --timeout value. USAGE: devicectl device notification observe --device <uuid|ecid|udid|name> --name <name> ... [--verbose] [--quiet] [--timeout <seconds>] [--json-output <path>] [--log-output <path>] DEVICE OPTIONS: -d, --device <uuid|ecid|udid|name> The identifier, ECID, UDID, or name of the device. COMMAND OPTIONS: --name <name> The name of the Darwin notification. This can be passed multiple times to observe multiple Darwin notifications. OUTPUT OPTIONS: -v, --verbose If given, provide more logging output than normal. -q, --quiet If given, output will include only errors. -t, --timeout <seconds> The overall command timeout in seconds. If this limit is exceeded the command is abandoned as a failure. -j, --json-output <path> An optional path to write a JSON file with command results. Note: JSON output to a user-provided file on disk is the ONLY supported interface for scripts/programs to consume command output. -l, --log-output <path> An optional path to write all logging otherwise passed to stdout/stderr. OPTIONS: --version Show the version. -h, --help Show help information. Executed command: xcrun devicectl device notification observe --device XXX --name com.example.Notification Result: Darwin notification observation started. 300.0 seconds remaining: On iOS, I'm posting a Darwin notification using: CFNotificationCenterPostNotification(center, CFNotificationName("com.example.Notification" as CFString), nil, nil, true) My CFNotificationCenterAddObserver on iOS does receive this notification. But the devicectl does not. Also no results when I remove the observer on iOS. How can I send a notification in such a way that it is picked up by the devicectl observer?

Xcode 16.3 repeatedly logs a same message very frequently, as fast as a single thread can. I use Instruments and Console and find out the log is: Needs flush! by -[DNTBrotliDecoder decodeBytes:length:] in DNTDocumentationSupport. The call is on a single non-main thread. I've tried to clear caches and it seems doesn't change. Yet I don't know exact point when the logging starts since launch. Fortunately, this thread is dispatched at E cores, bringing approximately 2 watts of power load to my Mac. Environments: macOS 15.4 (24E248) Xcode 16.3 (16E140) M4 chip

Hello, I am trying out Xcode Cloud for the first time. I could connect to Github in the initial setup and had a few failed builds (package resolution error), which I resolved fairly quickly. Now whenever I am trying to build, I get the following error: Xcode Cloud is unable to connect to the repository “<respository-name>”. Reconnect the repository to resume builds. I am unable to remove the connection from settings as well because it's stuck in a loading state. Is there a way to fix this?

Hi there, When I deploy my app to the iPhone for testing, I get the following error: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.4gpZFc/extracted/c_mll.app : 0xe8008018 (The identity used to sign the Please ensure that the certificates used to sign your app have not expired. If this issue persists, please attach an IPA of your app when sending a report to Apple. executable is no longer valid.) My account was mistakenly deactivated by Apple last month. After appealing, Apple restored it at the end of last month. Currently, my Apple Developer account seems to be working fine. Today, I recreated the developer certificate and identifier, added the account in XCode, everything seemed fine, and I clicked the XCode button (Start the active scheme). The build was successful, but I got the error: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.4gpZFc/extracted/c_mll.app : 0xe8008018 (The identity used to sign the executable is no longer valid.) Both my certificate and identifier were created just a few hours ago and show no issues. Before my account was deactivated, everything was working fine. I used a regular non-Apple developer account in XCode and performed the same steps, and it worked fine. I looked at relevant posts on the forum and tried the suggestions, but none of them solved my problem.

When I compile my Xcode project using the xcodebuild command, I observe long incremental build durations. For example, compiling a new, empty project in Xcode only takes around one second. The same project takes 7 seconds to compile using the xcodebuild command. I've noticed that xcodebuild hangs at the "GatherProvisioningInputs" phase. Steps to Reproduce: Create a new Xcode project (iOS app template) Build the project in Xcode with timing summary enabled Build the same project from the command line with the following command: time xcodebuild -destination 'platform=iOS Simulator,name=iPhone 15 Pro,OS=latest' I would appreciate any insights or suggestions on how to improve the build times when using the xcodebuild command. Thank you in advance for your help!

So Xcode has projects. And I breakup my code/libraries/targets into those. So why after 20 years of Xcode, can a workspace, that holds projects not display the same project opened in another workspace? The workspace redirects all output the project would normally generate in DerivedData to a completely different folder by default. What this means is I have to shut one workspace, and then open the other workspace with a different set of projects to see the ones that are shared. The workspace can't build because it can't open the project shared with another one that is open. VS sln files don't have this issue, so why do workspace files.

In Xcode I've: select Product / Scheme / Edit scheme tap on Archive on the left hand side of the select post actions and + to add a new script Then in there I have added a script I want to run on the archive after its created. I'd like to be able to see the output the script churns out as it goes along but doesn't seem possible? If I just add something like echo "hello" to the start of the script then I don't see "hello" visible anywhere when I build an archive (via Product/Archive). I'm looking in the build navigator. Is there somewhere else to look or is it possible to get the logging into the navigator?

We have multiple Jenkins jobs running UI Tests on a Mac with a device attached. This works most of the time but sometimes the tests don't run and the xcreport generated has an error like: BCOVBRDCoverageUITests-Runner encountered an error in BCOVBRDCoverageUITests failed with: Failed to install or launch the test runner. (Underlying Error: Failed to create directory on device 'Brightcove's iPhone 14 Plus' (00008110-000C54912246401E) to hold runtime profiles for application with bundle ID 'com.brightcove.BCOVBRDCoverageUITests.xctrunner': (null). (Underlying Error: The system failed to get the path on the remote device for the provided domain. (Underlying Error: The connection was interrupted.))) Has anyone else run into this? Any ideas on how to get around it? Kicking off another job after seeing this behavior works fine. The failures seem to be random or we haven't noticed a pattern yet.

I am trying to setup a unversal linking for my new developing app. but it look like not function well. did any one have some examples or demo domains suggest to use? In fact finally my app is just internal using, user will not suppose connect to internet , how can I using the universal linking without a website ? Thanks

Hi everyone, (you can answer in french) I’m french-rookie in xcode, and I have a problem: I’m trying to choice my custom font to add it in my Main.storyboard button, but it not works. I have my « Font provided by application » line in my Info.plist, with the name of my font in [0] (See images below) When I’m on storyboard button, I chose « custom » in font selector, then display font list but my custom font doesn’t appear. I already tried to install the font in my mac, but still stucked, nothing change 😭 Could you help me please? Thanks a lot (I specify that I scrupulously followed the way of doing explained on the Apple official page: Adding a Custom Font to Your App )

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.

I am using GoogleMobileAds package dependencies and now when I want to archive and export an app I get this two warnings : Upload Symbols Failed The archive did not include a dSYM for the GoogleMobileAds.framework with the UUIDs [13B55A37-D103-36E1-8D7B-FA4EAB2C8146]. Ensure that the archive's dSYM folder includes a DWARF file for GoogleMobileAds.framework with the expected UUIDs. Upload Symbols Failed The archive did not include a dSYM for the UserMessagingPlatform.framework with the UUIDs [A3941120-02A1-30B5-8C28-BFC0F9496E16]. Ensure that the archive's dSYM folder includes a DWARF file for UserMessagingPlatform.framework with the expected UUIDs. I have updated the packages to 11.9.0 (lasted) and Xcode 16 to 16 RC (lasted also) and I would like to know how to fix this... With Xcode 15 I have no problem !! I can export with no warnings ! But now with Xcode 16 no... Thanks for helping !

Hi, I'm trying to plan some roadmaps out and also have some issues with ios 15.0. Since it's no longer supported by Apple, any word on if/when iOS 15.0 will be removed from the "minimum deployment" version list in Xcode?

Got emailed three .txt crash files. Cannot for the life of me figure out how to get Xcode to do something with them. Tried: renaming .txt to .crash Dropping onto "devices and simulators" window Dropping on to "devices and simulators > select device > View device logs" "Download debug symbols" for the archive in Xcode (says "dowloaded debug symbols" so did it) ... and many other things Xcode 13 simply refuses to respond to the drag-and-drop of the file no matter the file extension and no matter where in Xcode's various windows/tools I drop it. Has anyone done this with a crash .txt file from app review and Xcode 13?

In previous Xcode versions, it was possible to add a folder reference to a project, and in the copy resources build phase it would copy the folder the bundle, rather than the contents (i.e. the folder's contents would be nested inside a directory named after the folder). In Xcode 16.4, when creating a folder reference, the copy resources build phase will copy the contents of the folder to the bundle at the root level (not nested), like the old behavior when creating a group rather than a folder reference. If you look at the raw project.pbxproj file, it shows up as a "File System Synchronized Root Group" rather than a "File Reference". Is there a way to get the old behavior, aside from hand-editing the project.pbxproj file?

I am editing my iOS project in Xcode 16 and want to use the "Swift Compiler - Upcoming Features" section of the build settings to selectively enable the new Swift 6 language features. I have read the instructions for doing this and have dowloaded an Apple sample project and can see that section under the project and target-level Build Settings in the sample project However, when I open my Xcode project in XCode 16 that section does not appear. Is there any way for me to influence how Xcode 16 displays the build settings? In fact, no "Swift Compiler" sections appear at all under my project Build Settings (All | Combined). There is a "User-Defined" section that has the Swift Version, Compilation Mode and Optimization level. The project itself is several years old and was on a very old project version. I have upgraded my project document format to "Xcode 16" but it made no difference. I have compared my project and the sample project in a text editor and both seem to have similar structure. I tried removing unused and outdated settings from my project but that also had no effect. Is there an alternative to deleting my project file and adding the source files to it? I have a large project with multiple targets so that would be something I'd rather not do.

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 struggling to build a driver for iPadOS in a particular project configuration. If I put the driver code and dext target into the same Xcode project which contains the iPad app, all is well. This is the way the Xcode driver template does it. However, I'd like to build and debug the dext on macOS, while eventually deploying on iPadOS. So I put the dext into a different project, which has a macOS target, a minimal iPadOS target and a DriverKit target. I made a workspace which contains both projects. I dragged the macOS project into the iPadOS project so that I can refer to the products of the macOS project (specifically, its driver target) as a dependency of the iPadOS target. Note that the main iPad app target depends on the driver target. So the workspace organization looks like this: Workspace iPad project main iPad app target (depends on driver) test project reference test project test macOS/iPad app target DriverKit dext target When I build the iPadOS target, it builds the dependent driver target in the macOS project, but it fails to link because Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/15.0.0/lib/darwin/libclang_rt.profile_driverkit.a is not found. If I just build the driver target directly in Xcode, there is no such complaint. I looked closely at the build logs, and I see for the failed link, there are these two linker flags set which are not set in the successful case -debug_variant -fprofile-instr-generate I can't seem to control the generation of this flag. I tried turning off the Profile switch in the Scheme editor for the driver, but is makes no difference. When I directly build the driver target, no -fprofile-instr-generate is set and it compiles and links. When i build the driver as a dependency of another target, -fprofile-instr-generate is passed to the linker, which fails. The obvious workaround is to put the driver source code into a separate driver target in the iPadOS project, but I'd rather have just one DriverKit driver for both platforms, with a few settings (such as bundle ID) controlled by a configuration file. Has anyone else encountered this problem, and know of a 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
