title: Adding objective c class that uses swift classes to bridging header Projectname_swift.h not found
body: <p>I have an objective-c class that uses swift classes. It all works fine.</p>
  
  <p>I wanted to import the objective-c class into a swift class, so I added its header file to the bridging header. All the sudden I got an error the Projectname_swift.h file is not found.</p>
  
  <p>Any ideas how to resolve this issue?
  Is it actually possible?</p>
