Why does CoreData Debug logging not work on my Mac app?

I can't get Core Data debug logging working.

I've gone into the arguments tab of my executable in Xcode and added:

-com.apple.CoreData.SQLDebug 1

as per the documentation and this question. And yes, I am on the Mac not on the iPhone.

What I've Tried

• Different compilers (LLVM 1.5 and GCC 4.2)
• Have all debug symbols included
开发者_Python百科
• Building i386 instead of x84_64 architectures

Another project I have shows the SQL debug logs fine. What on earth am I missing here?

Well, it doesn't help that I set the store type to XML. What a numpty. As soon as I changed it back to SQLite all logging resumed perfectly.
