XCode 10 rebuilds entire app plus UI tests when running a single logic test

I have a scheme with an app target, UI test target and a logic test target.


In Xcode 9, when running a single logic test, it only rebuilds the logic tests.


In XCode 10, it rebuilds the entire app (thousands of files), plus the UI test target, and the logic tests, when running a single logic test.


Am i the only one experiencing this? I guess it has to do with the new build system?


Workaround: Create a seperate logic test scheme and add the logic tests to that. Not cool though, as i cannot trigger the logic tests from testing the main app scheme any more, and i would like the logic tests to be on my main app scheme as always.
