title: How to use the debugger with nested static libraries in Xcode?
body: <p>A project that I've inherited has the following structure:</p>
  
  <p>Project A produces a static library.</p>
  
  <p>Project B produces a static library and links with library A.</p>
  
  <p>Project C produces the executable and links with library B.</p>
  
  <p>When I run app in debug mode, I can successfully debug code within the executable (project C) and the static library from project B. I can't, however, debug anything in the Project A library -- my breakpoints are ignored. I've checked and made sure that debug symbols are enabled and not stripped. Is there something else I'm missing?</p>
  
  <p>Thanks</p>
