Modify the definition of the function named greeting to return a String and replace the println statement with a return statement. The function should return a greeting. For example, if you pass in a string "Tom" then the return string would be: "Hello Tom".
func greeting(person: String) {
println("Hello \(person)")
}

Modify the definition of the function named greeting to return a String and replace the println statement with a return statement.
This challenge is asking for couple of things
- replace the println statement with return statement.
- since the println has been replaced with return, you should also set the proper return type for this function.
func greeting(person: String) -> String { // function now has return type String
return "Hello \(person)" // replaced println with return statement
}
Hope that helps.

Treehouse Guest TeacherHello William,
To tell the function the type you want to return, you'll add the following to the method signature.
func greeting(person: String) -> String
Instead of calling println, you'll want to use the return keyword like so.
return "Hello \(person)"
I hope this helps.

returnstatement, you can simply use the following.return "Hello \(person)"William Li
