When I use Instruments to record Allocation, the phone will display a dialog box indicating that the phone is unlocked when the screen is locked, as shown in Figure 1. When I have started recording allocation and lock the screen 10s later, the allocation can be recorded normally. For details, see Figure 2. I want to know why. Start recording for 10s and lock the screen on the device. The recording can be performed normally. What is the principle of this?

Instruments freeze when WKWebView is created I create a very simple mac os application If I create a WKWebView like this " (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. self.webview = [[WKWebView alloc] initWithFrame:NSMakeRect(0, 0, 500, 500)]; } " Then the instruments freeze when I record allocations Why? If I remove the creation of WKWebView, everything works fine I'm using Xcode 14.2

I just downloaded Xcode 15 RC and iOS 17 RC on an iPhone Xr. When running the app it seems to run fine however when trying to run in profile mode I get the error: Failed to install embedded profile for com...* : 0xe800801f (Attempted to install a Beta profile without the proper entitlement.) Verify that the Developer App certificate for your account is trusted on your device. Open Settings on the device and navigate to General -> VPN & Device Management, then select your Developer App certificate to trust it. Does anyone have any insight into what the issue may be? There is nothing to select within VPN & Device Management when I navigate there

Steps to reproduce: Open Instruments app Settings Select recording tab (Next to General) Click Open Keyboard Shortcut preferences to produce the aforementioned error. Profiler Version 15.1 (15C65) - Instruments macOs 14.1.2 (23B92) Thanks all.

I'm tracing a process, specifically focusing on the Metal device track, which records frames from other processes like Terminal, WindowServer, and sometimes processes that utilize the GPU. I attempted tracing with all apps closed and only Instruments running. However, it also records traces for Instruments. This behavior wasn't present in previous versions of Instruments. Was there a recent change in Instruments/Xcode 15.0.1? I cannot find any relevant information about this in the release notes either. Is there a way to configure Instruments to record only the running process?

Hi, I have a few traces where I have samples for kernel (and other processes), yet kernel is always 0 for any CPU Counter selected. There are other processes with an equivalent number of samples where the counter values appear. Perhaps there is a bit of 'art' to get the kernel counters to populate? I am trying to understand the workload from the system perspective (not simply the narrower process perspective), and it would be helpful to have the counter values. I've tried running for extended durations, yet that doesn't seem to adjust the counted events. I've adjusted to include "High Frequency Sampling" to resolve issues with VMware counter collection. Yet.. I need help to enable counter values to appear for kernel. Sam
