I would like to retrieve operation lengths of different metal GPU informations in form of xml. I know that exporting is possible using xtrace but how could i export the information of all wire memory statistics for example that are shown in the regarding row inside instruments. It would be helpful to get the xpath something in the GUI of Instruments belongs to. Specifically i am looking at Metal GPU traces. Any help is much appreciated! —toc gives a list of all contents but no description or affiliation with data in the GUI.

Xcode13.2.1 How To Resolve Energy Log

Hi, I'm using XCode 12.5 on Big Sur. When running the Time Profiler, I'm getting an error "required kernel recording resources are in use by another document". I tried restarting XCode and my computer but it still didn't work. Any idea why?

I have 3 devices. One is iPhone 7 plus which system version is iOS 14.8. and the others are iOS 15.1, though one is iPhoneX , one is ipad. When I use xcode to run my app, I find out the memory keeps rasing in iOS 15.1. By using instruments, I could see there're a lot autoreleasepoll content(which is growing more and more). But it doen't happen on iOS 14.8.

I'm in the process of refactoring a humongous monolithic app with multiple extensions into a setup where we have a service library which is linked to each of the targets. However, this causes a significant issue when the service library is being referenced from the notification extension, as that extension has a hard memory limit of 12MB on an iPhone 5s, which we are still supporting, and our memory usage is at about 11MB which is way too close for comfort. When the memory usage surpasses the limit, the notification extension is automatically killed by the system. Profiling with Instruments/Allocations has shown that a significant chunk of that memory is allocated (wasted, really) by the internal AVSecondScreenController.load() class initializer from the AVKit library. My approach is now to try to figure out what causes AVKit to be loaded in the first palce. I have no explicit imports for AVKit in the notification extension and attempts to figure out what triggers it from the service library failed as well. I did add a symbolic breakpoint for AVSecondScreenController.load() which is hit, but the backtrace is useless. Does anyone have any idea how I can pinpoint what causes AVKit to be loaded in the first place? Thanks!

I have a custom Xcode 13.2.1 (13C100) Instrument to which I have recently added os-signpost-point-schema. I notice that the events are marked with a hyphen/dash rather than a ⓢ. See the comparison of the signposts in my custom tool vs the standard “Points of Interest” tool: I have been digging through the documentation and while I am wagering that there is some simple attribute that can be set to dictate which symbol is included within the signpost circle, but it is not jumping out at me. How does one select the symbol used within custom event points in Instruments? FWIW, here is my Instrument: <?xml version="1.0" encoding="UTF-8" ?> <!-- Instruments Developer Help: https://help.apple.com/instruments/developer/mac/current/ --> <package> <id>com.robertmryan.CustomInterval</id> <version>0.2</version> <title>Custom Points of Interest</title> <owner> <name>Robert Ryan</name> </owner> <import-schema>os-signpost</import-schema> <!-- See https://help.apple.com/instruments/developer/mac/current/#/dev536412616 --> <os-signpost-point-schema> <id>custom-point-schema</id> <title>Points</title> <owner> <name>Robert Ryan</name> </owner> <purpose>Provide mechanism for multicolored events posted by `os_signpost`; The string generated by `os_signpost` must be in form of "Label:%d,Concept:%{public}@", where "Label" is string that will control what text appears in the event, and "Concept" is one of the strings listed in https://help.apple.com/instruments/developer/mac/current/#/dev66257045 that dictates the color of the interval.

My team and I have watched all of the WWDC 2018 &amp; 2019 session on signposts and custom instruments, and scoured the internet for documentation and examples... but the resources out there on instruments are thin.It appears from WWDC videos that it should be easy to arrange (other than alphabetical) and add colors to signposts in instruments with either a instruments setup, or a little XML... but without needing Clips. Is this true? Any example code (or just configuration)?

Hi all, I'm facing a strange timeout problem in my application. I've opened another thread for that [Receiving "The request timed out." when using NSURLSession].(https://developer.apple.com/forums/thread/696762) Based on Xcode 13 Network Instruments, when a network request receives a timeout, all the subsequent ones receive the timeout too. Those requests are hitting the same host / domain that works with HTTP/1 (head of line blocking?). Instead, other request that do not involve this domain are working correctly. I've collected a trace but I cannot understand the meaning of "No Connection" and the red color of the box under inspection. Are you able to clarify their meaning and when this scenario could happen? Thanks, Lorenzo

Is it possible to use the new http traffic instrument with combines dataTaskPublisher? How can I set a label to the task?

Hey,i got an issue with Instruments 7.1 when i try to profile my app. It works great in simulator, but when profiling on the device my symbols only show up as addresse:The menu item File -&gt; Symbols only after i stopped recording, not before. This is what i get:when i try to locate and select the dSYM in DerivedData -&gt; MyApp -&gt; Build -&gt; Products -&gt; Debug-iphoneos i just get the error message: The specified path didn't locate a dSYM for any of the selected libraries.Any help would be really great 🙂

In the App we saw a 4 seconds loading time while launching the App. Sometimes this time up to 8 seconds but the average time is 4 seconds. What could be the reason? In the AppDelegate there isn't server calls. The breakpoint inside the AppDelegate function didFinishLaunchingWithOptions is taking 4 seconds to get in. I have some api calls but they are launched after the breakpoint in the AppDelegate. The Api calls responses are working faster. In Instruments I have some blocked time, is it normal? Is something wrong in the log?

I have seen that I can export table data from traces containing Allocations, Leaks, and VM Tracker instruments using xctrace export on the command line in XCode 13 release notes. But I still cannot see the table data when I use xctrace export --input ***.trace --toc. How can I export given .trace using supplied query to the XML file format that can be later read and post-processed

I'd like to confirm the battery usage of an app I am developing on iOS, specifically on Xcode 13 and iOS 15. (Note: This app previously showed no issues with battery usage on previous versions of iOS.) Previously, it seems that there were two ways to gather energy usage information: #1. On the device under Settings > Developer > Logging As per Apple's documentation described in the section titled "Log Energy Usage Directly on an iOS Device". However, on iOS15, I can't find any options for logging under Developer or anywhere under settings even when searching. #2. Profiling via Instruments using the "Energy Log" template As per the same documentation from Apple described in the section "Use the Energy Diagnostics Profiling Template". While it is still available in Xcode 12, this template is missing in Xcode 13. Naturally, it's also not possible to profile an iOS15 device with Xcode 12. Digging through the Xcode 13 release notes, I found the following: Instruments no longer includes the Energy template; use metrics reporting in the Xcode Organizer instead. (74161279) When I access the Organizer in Xcode (12 or 13), select an app and click "Energy" for all versions of the app, it shows the following: Apple's documentation for "Analyzing the Performance of Your Shipping App" says: "In some cases the pane shows “Insufficient usage data available,” because there may not be enough anonymized data reported by participating user devices. When this happens, try checking back in a few days." Well over a year into production and having sufficient install numbers, I have a feeling that waiting a few days might not do much. I would like to determine if this is a bug in my app or a bug in iOS15. How can energy usage data be gathered using Xcode 13 on iOS 15?

When I try to run my iOS app through the Leaks instrument in the simulator, very shortly after launch, without fail, it will stop with the error "An error occurred trying to capture Leaks data"All the disclosure says is "Error retrieving leak information." I can't find any other information. Checking the console view, it just shows a normal run up until "&lt;End of Run&gt;"I've tried doing a clean build, deleting my derived data, uninstalling the app from the simulator, restarting Xcode, rebooting. I have no idea what to do.

Hello, I'am trying to analyse a hang with our App and asked the customer to do a ktrace artrace ("sudo ktrace artrace") on his system. The problem is that the macOS symbols are missing when I open the trace with Instruments on my system. the customer is running macOS 11.6.1, I'am running macOS 12.0.1. I asked the customer to do a sudo ktrace symbolicate but that does not help. This is a very important workflow for me to analyse sluggishness and hangs on systems, any help is welcome! :-)

"xcrun xctrace record --device " commands starts recording info through instruments and store it in a file but sometimes it run properly and sometimes says following "Waiting for device to boot" I have also tried xcode 13.1 CLT Checked on multiples devices Changed cables as well
