po, Print Object Description
Textual representation of the instance at hand.
The runtime system provides a default representation, however we can customize it for any type by conforming to the
CustomDebugStringConvertibleprotocol.
Conforming to this protocol changes only the top level description of that type (not the nested properties)
pois actually an alias toexpression --object-description
p, print
In
pwe can see that the result of the expression is assigned to a$Rxvalue that later we can use to reference that object in our debugging.
v, frame variable
vdoesn’t compile any code, and has a different syntax than the language that you’re debugging
po vs. p vs. v
