Could not attach to pid

Xcode 12.4, when i run the UITest,it show :"Could not attach to pid : “57128”"

+1

this is connected with M1 and the project run from Xcode with Rosetta. I have the issue described every time I run UI test.

If I run the project without Rosetta, the issue does not appear and XCUITest works as expected

attach failed ((os/kern) invalid argument)

If you turn off "Debug Executable" in the Test action of the scheme, are you able to run your UI tests successfully? You may receive a slightly different but more descriptive error if you run your tests with the debugger turned off, or the tests may run successfully.

Either way, please file a Feedback Assistant for this issue. If you could attach the xcresult bundle that is produced from running your tests, as well as a sysdiagnose, that will help us investigate the issue.

  1. To access the xcresult bundle, click on the Report Navigator, then right-click on the Test node and select "Show in Finder".
  2. To capture a sysdiagnose, run sudo sysdiagnose from the command-line.

I've turned off "Debug Executable" and get this error:

That is from the template app with autogenerated UITests
