You inverted the 2 parameters greeting and language so when you call the function passing the string "Tom" it is associated to the parameter "language".

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

    return (greeting, language)
}

var result = greeting("Tom")
