title: Missing symbol names while profiling in Instruments 7
body: <p>I don't see any symbol names when I'm profiling application for iOS 8.</p>
  
  <p>If I run profiler on simulator with iOS 9 everything works fine. Then I close instruments and switch to simulator with iOS 8.4 and I can see only hexadecimal addresses which reference to assembler or 'unavailable' content. Other threads are unnamed and everything, including system names are shown as binary pointers.</p>

  <p>Instruments can't find dSYM file, so I tryied to re-symbolicate app as <strong>File ▸ Symbols...</strong> then I select missing symbols and there is option to locate dSYM file.</p>

  <p>After select dSYM file, I get this message.</p>

  <p>And it's over. I also tryied restart PC, rebuild application, clean project, delete Derived Data, reopen XCode and Instruments, reindexing files <a href="https://stackoverflow.com/questions/12112394/missing-symbol-names-when-profiling-iphone-app-in-instruments">from this post</a> but it has no effect.</p>
  
  <p>Thanks.</p>
