It’s an exception, so use the Xcode breakpoints panel to add an all-exceptions 
breakpoint: press the + button at the bottom left of the pane, choose “Add 
Exception Breakpoint”, press “Done” in the bubble that pops up. Now Xcode will 
stop in the debugger whenever an exception gets raised. (It may not have logged 
anything about the exception to the console yet, though; some of those messages 
are logged by the code that _catches_ the exception, which won’t have been 
reached yet.)

IMHO everyone should enable exception breakpoints in all their projects. They 
are a life-saver for debugging.
