Why is "var result = greeting("Tom")" incorrect? It works in the playground.

I can't tell if I'm totally misreading the challenge or what.

This seems dumb as the code you've provided is valid as far as I can tell, but can you try swapping the order of your arguments in the greeting function? i.e. have greeting then language (and remember to update the order in the return statement too).

This really shouldn't matter, but it might be that the Treehouse challenge specifically is being picky even though your code is technically fine. I did the challenge quickly and did nothing differently from you other than the above, and it worked fine.

...Or, maybe I'm being blind and missing something else :)

That worked. Thank you so much. I feel a bit silly since it was so easy.

You need to initialize the two constants language and greeting. This is what the code should look like...

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

return (greeting, language)

} var result = greeting("Tom")

Sorry Kyle, that doesn't seem to be helping me at all. It's not accepting that, either.

I need help with task 3 for this challenge! "Using the println statement, print out the value of the language element from the result tuple." Where is this result tuple? I have done the 2 previous tasks right.

Thanks

You will most likely be able to get better help for your problem if you make your own question on the forums :)
