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

p prints value of primitive variable or value of a reference
po try to call -description for that object and print returned string

There is also **v command** in lldb. Explaining using example.

protocol Activity {} 
struct Trip: Activity { 
var name: String 
var destinations: [String] 
} 
let cruise: Activity = Trip(...)

Using v command 
(lldb) v cruise.name
(string) cruise.name = "print name"
//As it uses dynamic resolution

Using p command
(lldb) p cruise.name
//execution interrupted
