Q:

Updated to Xcode5 simulator through get SIGABRT Error

An app I recently started and working its keeps crashing with a SIGABRT message.  The general message at the top of the debugger says:
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIView 0xb651580> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key parentEmail.' 

... At the the bottom it says:
libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb)

Let me know if the "first throw call stack" info is necessary to solve this one. 

A:

Check and make sure that you didnt previously have a button/text field/label previously linked with an action, then deleted that item.  The link still exists.  Check and make sure that all your links match to existing items.
