I just printed an NSArray in the debugger and this is what it returned:

<_PFArray 0x12ff90200>(
   // some data was in here
)

But what is a _PFArray?

It's a subclass of NSArray used by the Core Data framework.

NSArray is a class cluster. This pattern is used extensively in the implementations, and largely discussed in other questions too. One example here: NSDate isMemberOfClass: [NSDate class] returns false?

So, in short, it is a subclass used to an specific internal purpose. Long answer, check the linked answer to begin reading on the subject.
