Using explicit parameter names

Swift Programming: The Big Nerd Ranch Guide (2nd E 12. Functions

Why there is an update of the printPersonalGreeting and you erase the last one in page 114? The readers like me, who are new programmers misunderstand that
func printPersonalGreeting(name: String) AND func printPersonalGreeting(to name: String)… with also word “to” are NOT the same functions. There name is different: The name of a function is with ( ) also as the book says in page 111.
I think it would be better for the reader to keep together the last also and just change the name in the call
printPersonalGreeting(to: “John”) like I did.
Am I wrong or is it because I am a new programmer?

You are correct, and you are also a rising star :slight_smile:

Example:

func foo (bar:String) {
    print  ("\(#function): \(bar)")
}

func foo (jibber bar:String) {
    print  ("\(#function): \(bar)")
}

foo (bar:"3 is the smallest odd prime.")
foo (jibber:"3 is the smallest odd prime.")

Output:

foo(bar:): 3 is the smallest odd prime.
foo(jibber:): 3 is the smallest odd prime.
