Q: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".
Not sure why this isn't the right answer... I can't compile the code either because it shows an error message.
func greeting(person: String)->String {
println("Hello \(person)")
return greeting("Tom")
}

Replace the print statement with a return statement and then call the function.
func greeting(person: String)->String {
return "Hello \(person)"
}
greeting("Tom")
