You usually take care of these sorts of errors with exceptions when an application is being created rather than at runtime.
Yes, but fatal errors are usually the type that can bring down the entire program, such as running out of memory or dividing by zero. An out-of-bounds exception often doesn't have to kill the program. Of course, if the developer wants it to kill the program, then they can override -[NSApplication run] to catch the exception and quit.
