Xcode debugger doesn't print objects and shows nil, when they aren't

Question

Xcode shows an error when trying to print an object with po , but only for one project.

Answer 1

I have run into this as well and when I found I was in release mode I switch to debug ... no fix. Turns out that I had to do a clean first (cmd+shift+k).

So I think what happens is that after built in release mode not everything is recompiled in develop and so lldb can't properly read the symbols. After cleaning and recompiling in develop it worked for me.
