Hey there,

It looks like you have 1/3 close, parts 2 & 3 are as follows:

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

    return (greeting, language)
}

var result = greeting("Tom")
println(result.language)

I agree with Jack. That's how I thought println(result.language) should have worked. Treehouse prompts with the Bummer message saying it returns "Hello Tom"

I put the code in a playground and got the same results.

So I used println(result.1) and the playground showed "English"

I entered the same println(result.1) in the Treehouse exercise and received the Well Done message.

Weird. I'll have to keep looking at this.

Okay. I found my error.

I had: return (greeting, language)

It should be: return (language, greeting)

Then you would be able to use:

prinlin(result.language)```
