Variable has wrong value

func greeting(person: String) -> (language: String, greeting: String) { let language = "English" let greeting = "Hello (person)"

return (language, greeting)

}

var result = greeting("Tom")

Why does the result variable not have the right value?

tuples.swift 
func greeting(person: String) -> (language: String, greeting: String) {
    let language = "English"
    let greeting = "Hello \(person)"

    return (language, greeting)
}

var result = greeting("Tom")

Sassyn,

Sorry for the error, It appears that the test wants a specific order for greeting and language. You will need to swap the order like so.

     func greeting(person: String) -> (greeting: String, language: String) { //greeting then language
     let language = "English"
     let greeting = "Hello \(person)"

     return (greeting, language) //greeting then language
     }

     var result = greeting("Tom")

Regards,

Chris
