Can't run unit tests in Xcode 8 with earlier unit test configuration : <p>I ran into this issue after upgrading to Xcode 8. When running the tests I get this error at run time:</p>

<p><code>/Users/&lt;me&gt;/work/&lt;appname&gt;/Build/Intermediates/&lt;appname&gt;.build/Debug-iphonesimulator/&lt;appname&gt;UnitTests.build/Script-231C35D610AC1F5000D830C2.sh: line 3: /Applications/Xcode.app/Contents/Developer/Tools/RunUnitTests: No such file or directory</code></p>

<p>The sh script in the error message is trying to access the RunUnitTests tool and  fails. I assume this tool has been removed in Xcode 8. It seems that for my project Xcode tries to run tests in a way that is no longer supported. If I create a brand new project no such script is created and I can run tests.</p>

<p>Any idea what settings I need to update in my project to get the tests running again? I tried the 'Update to recommended settings' checklist but it doesn't solve this issue.</p>
