Right now, NSException::GetSummary() has the following output:
"name: $exception_name - reason: $exception_reason"
It would be better to simplify the output by removing the name and only
showing the exception's reason. This way, annotations would look nicer in
the editor, and would be a shorter summary in the Variables Inspector.
Accessing the exception's name can still be done by expanding the
NSException object in the Variables Inspector.
