title: Xcode 6.1.1 LLVM/Yosemite breakpoints not working in Mac OS project
body: <p>I have several projects recently moved up to Xcode 6.1.1 from Xcode 4.6. </p>
  
  <p>The iOS projects debug as expected, but the Mac OS projects do not. Breakpoints have no effect. Code execution continues without stopping.</p>
  
  <p>Is this a known issue? Is there a suggested solution?</p>
