title: Xcode5 debugging on device - EXC_BAD_ACCESS
body: <p>I updated to new MacOS(Maverics) and to Xcode5. When i try to run and debug on device (ipad mini, iphone4 and 5), application starts and when I hit break point and click on step over or continue I get:
   <code>EXC_BAD_ACCESS code =1, address 0x0</code>. </p>
  
  <p>It is quite strange because it happens on line where is: 
  <code>NSLog(@"Something");</code>...</p>
  
  <p>I tried to give my code to other colleagues and everything works without any problems ...</p>
  
  <p>I tried to reinstall Xcode, reboot all devices and install all available updates - situation is still same.</p>
  
  <p>Any tips on this? 
  thanks</p>
  
  <p>Edit:
  I found that, Bad Access is problem only on older ios versions. IOS 7 devices are okay. </p>
