title: How to debug an iOS app crash at launch time, breakpoint only in assembly file
body: <p>I'am facing an issue with an app currently in development.
  The problem is that the App crash at launch time when it was in background for a while, and only in that case.
  Launching the app while it was killed doesn't lead to crash, from debugger or from phone.
  Launching the app while it was in background for about 5-10 min doesn't lead to crash, while debugging or not.
  Launching the app while in backgorund for about 15-20 min lead to a crash. Using debugger and breakpoint on exception gave me this file :</p>
