title: Xcode doesn't show the line that causes a crash
body: <p>Every time my app crashes Xcode highlights the UIApicationMain() call in the main() function as the line that caused the crash. In some cases that used to be normal (segmentation fault for example) but the crash I am trying to deal with is a simple SIGABRT with detailed information logged in the console:</p>
  
  <pre><code>*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFDictionary setObject:forKey:]: attempt to insert nil value (key: Date)'
  </code></pre>
  
  <p>Xcode used to show the line just right with older SDKs but since i upgraded to Xocde 4.2 that changed. 
  It is pretty obvious that Xcode knows exactly what caused the crash (or could know), but its still not showing the actual line. Is there any fix or workaround for this?</p>
