@Dave DeLong pointed out right.

Workaround

  • Find when the exception thrown, which viewController is being loaded.
  • Then check the nib file of the viewController, there must be an IBOutlet attached in xib but might be missed in the viewController.h file or might be some control which was attached is missing in xib file.

Why running in Simulator? Sometimes it ends in messing up.

Just do the steps

  1. Build -> Clean
  2. Build -> Clean All Targets

Now it runs the real code, may be issue got resolve on device also or may be it start throwing exception on simulator also in case if there is really an issue. (I already have mentioned workaround)
