Regarding renaming parameters will break the API. Swift supports giving 
a different name which are used locally:

func copy(_ source: String, to destination: String)

Should be called like this:

copy("foo", to: "bar")

`_` indicates that the argument can not be named when calling the 
function. `to` is the name that is used when calling the function. 
`source` and `destination` are the names used locally in the 
implementation of the function.

This allows to rename a parameter (the local name) without breaking the API.
