Using array subscripting, retrieve the string "bread" from the array and assign it to a variable named cart. Help!

I attempted to removeAtIndex() and I looked up documentation on subscripting. I made it work in both instances in my own playground, but I can't seem to move forward with the work on treehouse. Please Help!

data_collections.swift 
var shoppingList = ["toothpaste", "bread", "eggs"]

if shoppingList.count > 0 {
    var cart = shoppingList[1]
}

Hi Matthias,

You're doing fine. There's no need for the conditional test. 

var cart = shoppingList[1]

That should be fine!

Steve.

Steve is right, you don't need the test to pass the code challenge, in fact putting that in there is why it's getting rejected. That said, it's good practice to checks of that flavor in the "real world".
