title: Xcode 4.2 not debugging properly
body: <p>I've imported an iPhone app that I have developed for iOS and am now maintaining it. I've came across a couple of bugs when trying to add to the iPhone's calendar, which I'm happy to try and sort out myself with a bit of debugging.</p>
  
  <p>One problem is that when I go to run the application on the iPhone simulator, it seems to run an older version of the app than the one I am running. I've removed and added another button since then and the old button is still showing when I run it in the simulator. However, when I compile and run this on a device, it loads the correct version and displays the correct version number in the 'about' view.</p>
  
  <p>But... my main problem is that it doesn't seem to debug on the device properly. The app actually works fine except for the calendar problems, but if I put a few breakpoints in so I can see exactly where this is going wrong, it just doesn't seem to step through! The app pauses, and Xcode says the app has paused! I can press step over and continue execution etc and it appears to work, but I can't see it stepping over the code, nor can I hover over variables to see their values.</p>
  
  <p>I've tried reinstalling Xcode multiple times (I did have a problem installing an older version, so I had to wait until the next version was available before Xcode would install).</p>
  
  <p>The stress is: Today is my last day at work, and I'd really like to get this app ready for iOS 5 before I leave.</p>
  
  <p>Has anyone seen these symptoms before? Is there a debug setting that I've missed? Or is it a corrupted installation?</p>
  
  <p>I wish I could help people a bit with more information, but I don't even know where to start looking here. Any code I can post? any settings? (not too familiar with this, I'm a .NET guy usually).</p>
  
  <p>Thanks!</p>
