How to see the query string of an NSPredicate or an NSFetchRequest?

Question

Is it possible to see the completed query string, with all the variables substituted to their actual values? Would be good for debugging...

You could just log the predicate with NSLog(@"%@", predicate). Most values will show directly, except those that are cast e.g. dates or bool. For those you will have to log the variable separately.

Yes, turn on Core Data debug and you will see the raw sql calls.
