What's the difference between “p” and “po” in Xcode's LLDB debugger?

Question

Example. I write the following string in my old project and a new, clear one:

UIInterfaceOrientation k = [UIApplication sharedApplication].statusBarOrientation;
         


        

Answer 1

• Use po, p, & v to print variables

  • po ends up compiling & executing twice, once to evaluate your expression and again to get the object description.

  • v doesn’t compile at all: can’t evaluate any expression but does allow property accessing and does recursive dynamic type resolution so each property is treated as the actual runtime type.
