title: Swift classes not found in Objective-C project
body: <p>I am working on an iOS project developed using Objective-C. I need to integrate some Swift files in it. So, did following:</p>
  
  <ol>
  <li>Added a new Swift file named "temp", so that <code>MyProject-Bridging-Header.h</code> is added by my Xcode IDE (Version 9.1).</li>
  <li>Added the Swift files, which I want to use, to the project.</li>
  <li>Changed target setting <code>Defines Module</code> to YES.</li>
  <li>Similarly, "Product Module Name" is set to "MyProject".</li>
  <li>I can see the <code>MyProject-swift.h</code> a file name for the setting "Objective-C Generated Interface Header Name".</li>
  <li>Added import statement for <code>myProject-swift.h</code> in one of my Objective-C .m files <strong>and was able to build the project successfully.</strong></li>
  <li>I checked in Finder that <code>myProject-swift.h</code> was created.</li>
  <li>Ensured the @obj prefix in the Swift classes declaration.</li>
  </ol>
  
  <p>Still, when I try to use any of the Swift classes, then I get compile time error "User of undeclared identifier".</p>
  
  <p>What can be the reason for the issue? Am I missing something?</p>
