I need to switch it off but I'm having trouble finding how. If any of you have Xcode 5, please be a dear and help me out. Thank you!

Why do you want to switch it off? If you need to keep an object in memory, then assign it to a global variable that can keep it in reference. Disabling reference counting is a sure fire way to have serious memory leaks...

FWIW, I designed and built a reference counting garbage collection suite for C++ that allowed us to have 10M lince of application code, and zero deletes (at the application level), yet no memory leaks. It is a subject I have spent considerable time on research and development.
