Time Profiler "Required Kernel Recording Resources Are in Use" Error

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?

  • faced the same problem with iPhone 11 Pro on iOS 14.6: XCode Version 12.5 (12E262) Mac OS Big Sur 11.3.1

    Enabling/Disabling BitCode didnt help Profiling same app on the simulator (i.e. iOS 14.5, iPhone 8+ Simulator) works fine.

I’m facing same issue in Xcode (Ver.12.5) on Big Sur (Ver. 11.2.3). I can workaround this issue by quitting Instrument completely (even from dock) in my case.

Hi everyone, sorry for the late reply, we believe this should be fixed in Xcode 13. Could you download the newest version from the AppStore (13.2) and see whether this fixes it for you? If you still encounter the issue, please file a Feedback.

  • @JoachimKurz - I had this problem in Xcode 12.5.1. Using Xcode 13.2.1 fixed it. Thanks!
