2,421 PointsStuck on Stage 2 Parameters and Tuples : Task 1
The task is
Challenge Task 1 of 2
Modify the existing greeting function to have an external parameter named person.
I entered this code from what I understand on the introduction of Parameters and Tuples. In Xcode this works well.
func greeting(#person: String) -> String {
return ("Hello \(person)")
}
greeting(person: "Riz")
Got this error message.
Bummer! You need to define a func named greeting that takes one String parameter named person.
I don't understand what is required here. Appreciate the pointers here.

This code snippet worked for me:
It looks like you have language then greeting, not greeting, language in the func paramaters.
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language)
}
var result = greeting("Tom")

For the first part you only need to add the parameter. person: String
func greeting(person: String) {
}

On the second task. I still don't get it. "Bummer! Your result variable has the wrong value in it. Check the task instructions again."
Checked the other forum thread. It seems I got it right but it's not af. I passed the greeting func to the variable results as instructed. Bit lost now.
func greeting(person: String) -> (language: String, greeting: String) {
let language = "English"
let greeting = "Hello \(person)"
return (language, greeting)
}
var result = greeting("Tom")
