Hello, anyone deal with an issue in the App Store Connect (trends section)? Few hours ago I logged in and checked the trends page, but it does not load. It takes a while and then the error: "An unexpected error occurred. Try reloading the page. If the problem persists ..." is being shown I guess it's an Apple issue or am I the only one experiencing this problem? Best, Jackson

When using instruments leaks to record a trace, and then using the xctrace symbolicate command to symbolize it, it will prompt that the symbol file cannot be found. record command like this: ‘ xctrace record --instrument Leaks XXXXXXXX"， only use --instrument parameter nor --template parameter. symbolicate commadn like this: 'xctrace symbolicate --input xx.trace --output ddd. trace --dsym /Users/xxxx/Downloads/dSYM' Below is the symbol translation error message： Gathering trace symbols info [2/2] Succeeded: 2/2 [Error] Cannot resymbolicate this trace: No dSYMs were found or relevant to this trace.

Hello, I see the Instruments app has gotten a nice upgrade for Xcode 16. There is one issue left that has been bothering me though. If my app is installed inside the "Application" folder, and I then try to launch Instruments for a new build of the same app from within XCode, Instruments will run the app installed in "Applications" instead of running the app I just built. The problem with this, is that it's very easy to accidentally profile an old version of your app, and come to the wrong conclusions. I've created a video showing this issue: https://youtu.be/IloFsQQFgSw

Hi, I'm sorry if my question is Hello, I apologize if my question seems worthless to you. I'm just starting out, it's my first day as an apprentice learning this programming language, and I don't have any community or mentor to help me. I searched for my answer in the Forum but couldn't find a solution, so I'm asking my question here. How can I, at the start of a project, choose an emulator device that includes other iPhones besides the 15 and 13? I'm looking for the iPhone 14. I'm currently using Xcode version 15.4. Thank you for your attention to my question. Have a great day.

Hi, Trying to convert the lsaw.csstoredump file in a sysdiagnose directory in to a human readable format. The readme file in sysdiagnose indicates ".csstoredump files: sysdiagnose generates the output of lregister/lsaw in a binary form. To convert these .csstoredump files to text files, use the following command: lsaw dump --file "PATH TO DUMP FILE" > lsaw.txt These files can also be opened in CSStore Viewer." But no such command lsaw exists, at least not on macOS 14. No CSStore viewer either. Any ideas where I can find this utility or convert the file? I know it's in .gz format so have also tried just decompressing it but it is still in a binary format. Also tried running strings on it but not useful. Thanks!

Hello! Is it possible to make App Thinning Size Report for app store distribution with command "xcodebuild -exportArchive -archivePath iOSApp.xcarchive -exportPath Release/MyApp -exportOptionsPlist ExportOptions.plist" ? https://developer.apple.com/documentation/xcode/reducing-your-app-s-size#Automate-the-generation-of-the-app-size-report I tried to do this by specifying "method": "app-store" in ExportOptions.plist, but it doesn't work. I get an empty app-thinning.plist as output. But when I specify "method": "enterprise", it works correctly. Is it true that App Thinning Size Reports are only generated when the archive is exported for Ad Hoc or Enterprise distribution (not for App Store) ?

There is a WWDC session about this cool instrument to detect hangs on-device: https://developer.apple.com/videos/play/wwdc2022/10082/ I very like this tool; it's handy and gives useful stack traces, but the threshold of 250 ms is practically too high to use in a testing environment. It would be better if there was an option like 100 ms or something like that. I think most of the people can see the scrolling hang with a duration of 100-250 ms, and it would be cool to detect such hangs with this instrument. Is there a way to set a lower threshold, or can Apple consider adding such a threshold? Thank you!

Trying to examine performance issues in Xcode Instruments using the Animation Hitches instrument in Xcode 16.0 beta 6 (16A5230g). When connected to my iPhone 15 Pro Max and I try to start a run with my app, it has an error “Failed to split user provided arguments: working directory doesn't exist” with timestamp “(Before Run Started)”. When running the app on an iOS simulator, the instrument runs fine—but I want to profile on a real device.
 Instruments > Settings, Recording Location set to Default and that directory does exist.

Hi everyone, I'm developing a visionOS app using SwiftUI and RealityKit, and I'm encountering an issue with the pivot points of primitive shapes created in Reality Composer Pro. Scenario: When I use Reality Composer Pro within Xcode to add primitive shapes (such as cubes, capsules, etc.) to my scene, the pivot points for these objects seem to be set incorrectly. The pivot is located far from the actual object, which affects transformations and positioning. Question: Is there a way to correct or adjust the pivot point for primitive shapes created in Reality Composer Pro? Additional Information: I’ve attached a screenshot illustrating the issue with the pivot point being misaligned. Any guidance on how to resolve this would be greatly appreciated. Thanks in advance for your help! Best, Siddharth

Hello, I'm trying to use the itmstransporter installer (iTMSTransporter_installer_linux_aarch64_3.3.0.8.sh ) I downloaded from my Mac using the following command: iTMSTransporter -m downloadInstaller -arch aarch64 -os Linux -destination ~/Downloads when I move it on the Linux machine and I run it I receive the terms to be approved, I write Yes and return, then it asks "Continue? [yes or no] " and again I write yes and return, but immediately the command quit without any output. Any idea what's happening?

Hello, I've upgraded both of my Apple TVs to tvOS 18. Since then, my app developed with SwiftUI has become almost unusable due to severe lag, particularly when scrolling in a LazyVStack. On the A1625 (Apple TV HD), the lag can last up to 20 seconds, while on the A2843 (Apple TV 4K, 3rd generation, Wi-Fi + Ethernet), it’s about one second. I can consistently reproduce the issue with this minimal example: @main struct MyApp: App { var body: some Scene { WindowGroup { ScrollView { LazyVStack { ForEach(0..<1000) { nb in Button("Item \(nb)") {} } } } } } } Using Instruments, I found that the hang is related to this call: 389.00 ms 71,4 % 6.00 ms +[_UIFocusRegionEvaluator __regionsByEvaluatingOcclusionsForBaseRegions:occludingRegions:baseRegionsCanOccludeEachOther:inSnapshot:] Unfortunately, I can't attach the Instruments trace directly here, but you can download it from this link: https://drive.google.com/file/d/1sEIwXhr7_ajjRHZevCIW6jNOlPjaeU6L/view?usp=sharing Important notes: The same screen, when written in UIKit, runs smoothly on both devices. After performing a factory reset on the older device, the performance issue disappeared. However, as you can imagine, I’m already receiving complaints from users who are understandably unwilling to reset their devices. Does anyone know of a workaround until this is addressed by Apple?

I cannot my AirPods 3rd gen to my phone it won’t play videos or music when connected. Screen bugs out some times doesn’t see when I swipe. Too many bugs .

Hi there, In a project that I am working on, whenever I try running instruments for allocations to see the memory allocations that are happening under the hood, I see the statistics, and the traces updating, however the chart never updates. I have made new projects on the machine, and I have tried different Xcode versions, and they all show the chart just fine. I have tried running the project on other machines with no success. I have double checked the arguments and options on the active schema I am trying to profile with the schema of a new project and they are identical. Here is a picture of how it looks: My questions are as follows: What properties and settings can disable the chart from showing up? What diagnostic steps recommended that I should take? I can not share a reproducible as this is the only project I have with this problem and it is not mine, but please tell me if there is anything else I can provide in order to debug this. All the best Parsa

Can somebody help me find the official documentation for instruments? Google brings you to this forum, then the link at the top of this forum for Instruments documentation brings you to the Xcode page, which links to these Apple developer docs, wherein a search returns nothing for "Instruments". Searching these Xcode docs for "Instruments" returns only this specific use case on analyzing HTTP traffic.

Recently, we reworked a crucial part of our app and managed to half the amount of CPU cycles our app requires (according to Xcode Instruments). Nonetheless, when using the Time Profiler component in instruments, it shows that the CPU time spent was either higher or the same (depending on execution). The main time-consuming factor here: libsystem_pthread.dylib - the amount of CPU time spent by this library has doubled from original implementation to reworked implementation. Therefore, I'm having a few questions: How should I interpret this result? How is this even possible if the CPU clock cycles halved? What is the better metric here, the CPU cycles or the time profiler? How can I reduce the impact of that said library? What does that library do and how can I influence its performance? Thanks in advance.

What exactly is included/calculated in the following metrics within RealityKit Trace - RealityKit Metrics - 3D render attributes: 3D Mesh Triangles Total Triangles Submitted 3D Mesh Vertices Total Vertices Submitted As the second part of the question, what differentiates between: 3D Mesh Triangles vs Total Triangles Submitted 3D Mesh Vertices vs Total Vertices Submitted

When I was using Instruments to test the Display on my phone, I discovered a long-duration frame. Below that frame, there were some gaps in the vsync queue. As I understand it, vsync signals should appear consistently and steadily. How can this behavior be explained? My phone is iPhone 15 Plus and iOS 18.

First of all, you cant unlock the device, even if you know the password. Thats one thing. Then, you cant use your main device to navigate trough the device you are controling. You basically can’t do shit to be honest. And Siri is on a bad mood this days. That’s what I have to say to you my friends. Eu amo vocês. beijos. Consertem essa porra. E o “Eye Tracking” está bugado também. Não funciona direito.
