returns.swift 
func greeting  (person: String) -> String {
    print ("Hello \(greeting)")
    return person
}

Hi Ross,

There are a couple of mistakes in your syntax.

  1. We need to return the name of the person. Right now you are returning the gretting function which is not right.

  2. You need to remove the print statement and just return the greeting like this.

func greeting(person: String) -> String {
    return ("Hello \(person)") // return the name of the person
}

I hope that helps,

Mike

PS: Thanks to the awesome resources on Team Treehouse, I launched my first app.

Now you can practice writing Swift code directly on your iPhone :-)
