enum instance method and method outside of the parentheses

Hi I'm a bit lost , please can someone explain in basic terms, why we call enum instance method inside parentheses and other methods outside of the parentheses relating to the same enum (or struct/class I guess).

what are the differences and what do each one do ?

many thanks

Can you provide a code example of what you are describing?

Hi Stone , thanks .sorry i haven't got any code at the moment . what I'm asking is ...

when an enum is written you can create a instance method which sits underneath the enum.

why do we do that and other times create a method/function outside of the parentheses of the enum ?

I've probably missed some basic principle of methods at some stage .

are you curious about enums in swift or objective C?

swift I'm doing enums and optionals but its probably a general question i guess for swift enums and struct etc . more to do with methods and their positioning .
