Our team is currently handling hang issues and logs received by the Organizer during our project. Regarding the xCode Organizer, we’d like to ask a few questions: The hang rate is presented as a bar chart for each app version. Is there any way to get detailed information for each versions? For example, what percentage of the hang rate is attributed to users on different iOS versions? We've encountered a situation where the hang logs have decreased, but the hang rate has increased. Could you explain why this might occur? I was wondering how the hang rate is sampled. For instance, does it record all users who experience a hang, or only those under specific conditions? The situation is that we can see only a handful of hang logs (around 13), but we have hundreds of thousands of DAUs. This ratio seems quite off. Could you explain what might cause us to receive such a small number of logs for each version?

Hey, In the UI of the Instruments app, I can change the recording mode to immediate. Is that possible when using xctrace? It seems to use deferred as a default. I've tried to create a template, set the recording mode to immediate, and use that template for recording. However, that doesn't seem to work. At least the exported TOC of the .trace will have the following summary: <summary> <start-date>2025-01-11T13:00:11.365+01:00</start-date> <end-date>2025-01-11T13:00:30.525+01:00</end-date> <duration>19.160279</duration> <end-reason>Target app exited</end-reason> <instruments-version>16.0 (16A242d)</instruments-version> <template-name>core_animation_fps</template-name> <recording-mode>Deferred</recording-mode> <time-limit>12 hours</time-limit> </summary> This issue might be related to: https://developer.apple.com/forums/thread/735948 Thanks a lot!

Hello, I would like to obtain the average CPU usage of a trace I ran through instruments by looking at the cpu profiler. Is there any way to do this? Or should I be using another instrument.

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.

I'm having an issue with my swiftui macOS application where it is continually consuming more memory over time and after a couple of hours will grind to a halt. I've watched a few videos now on how to use Xcode Memory Graph and Instruments to identify the source of a leak (I assume it is a leak). These videos all provide very obvious issues as examples but mine seems more elusive and I don't know how to identify which part of my code is the cause of the issue. After running instruments I see the following but the leaked objects are not always consistent: Xcode Memory Graph shows NSSet as the culprit which is shown under CoreFoundation (not my App). I really am a beginner here and because it's not showing me somewhere in my app that I can go and investigate I'm really stuck.
