title: App crashes after updating it
body: <p>I recently sended out an update of my app. Now I got some complaints from people who says that the app is always crashing. When I check it on the simulator and on device everything works properly.</p>
  
  <p>Now my question is, has this something to do with my update.
  Maybe this has something to do with my core database that I'm using or maybe something else?</p>
  
  <p>Hope that anybody can tell me what the problem is?</p>
