why do we return values such as strings etc

I'm doing swift and wanted to know, basically why do we return values after the function name in some functions and methods and not in others. ?

theres probably a very simple answer. many thanks

um, because we want some function to return values and other not to. It's just how values are passed around (parameters and return values). A language that didn't work this way would probably have to just store values in some global scope to pass them around. It would be horrible to use, and would have scope implications (it's preferable to have things be somewhat insulated and deliberate). (i hope i understood the question)
