This still seems to be a problem. Tried with an Xcode project macos command line tool template, and with a SPM exectuable target. Both show empty concurrency instruments but the time profiler is fine.

We're also relying on this on Xcode 12 so if it's no longer supported it will be a big blocked for us. Not all dependencies work yet on M1 so this seems necessary. https://github.com/braintree/braintree_ios/issues/564

Forcing the ENABLETESTINGSEARCH_PATHS = YES to my dependencies (Kiwi) seems to make them compile, but then the test target fails. Even with that setting turned on in the app and test targets.  note: did not find header 'XCTest.h' in framework 'XCTest' (loaded from '/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator14.0.sdk/Developer/Library/Frameworks') Seems like it's because some libraries still use the old style of import "#import <XCTest/XCTest.h>". I'm not sure anything can be done to fix that.
