title: Can't use Swift classes inside Objective-C unit test
body: <p>I have followed <a href="https://stackoverflow.com/questions/24206732/cant-use-swift-classes-inside-objective-c/27251979#27251979">this</a> recipe in order to use a Swift class in an existing Objective-C project <code>MyProject</code>. That works fine. </p>
  
  <p>However, I'm still not able to use the same Swift class in the same project's unit tests. The compiler marks the line where my Objective-C unit test says <code>#import "MyProjectTests-Swift.h"</code> with <code>file not found</code>. </p>
  
  <p>If tried changing the test target's <code>Product Module Name</code> from its default <code>MyProjectTests</code> to <code>MyProject</code> as suggested in a comment to <a href="https://stackoverflow.com/questions/24367982/objective-c-test-class-using-swift-code">this</a> (unanswered) question. However the compiler now marks the line where my Objective-C unit test says <code>#import "MyProject-Swift.h"</code> with <code>file not found</code>. </p>
  
  <p>So how can one integrate Swift classes into (XCTest) unit tests that are written in Objective-C? Does Apple provide any recipe?</p>
