title: Compile errors don't show up when using XCTest with swift
body: <p>it doesn't seem like anyone has had this issue before but I'm using Xcode 7.3.1 and started adding some UI Test Cases with swift. When I use swift there are no compile errors or warnings that show up. So when I do something wrong it just says "Build Failed" but doesn't say why. Nothing shows up anywhere. </p>
  
  <p>Yet when I make the tests in objective C it works just fine with the compile errors and warnings and NSLocalizedString works too...</p>
  
  <p>Does anyone know how to make Xcode show the compile errors and warnings on tests that use swift?</p>
