I recently upgraded to Xcode 4 and have not yet figured out how to have exceptions and error messages logged to the run console.
Example: In Xcode 3, [[NSArray array] objectAtIndex:1] results in the following being logged to the console.
2011-08-10 10:27:22.061 App[28662:40b] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSArray objectAtIndex:]: index 1 beyond bounds for empty array'

This exception does not log anything to the console in Xcode 4.
I am able to view the call stack by adding an exception breakpoint - however, continuing past the exception breakpoint does not log anything to the console (not even a vague SIGABRT or EXC_BAD_ACCESS message).
I have "Log Exceptions" and "Enable Zombie Objects" checked in the Edit Scheme window's Diagnostics tab, but it hasn't helped. Are there any other settings I could possibly be missing?
Thanks so much.
