Don't know if i am doing this right

I really don't know if i am doing "Creating a Data Model" correctly.

The question is: We are at the grocery store and we picked up the bread. Using array subscripting, retrieve the string "bread" from the array and assign it to a variable named cart.

and this is what i wrote:

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

var cart = ["",]

shoppingList.text = cart["bread"]

Hi Daniel,

You're almost there, if you remember back to the introduction to Swift course arrays are based upon integer indexes which means unlike an dictionary we need to use a number between 0-2 because arrays start at the zeroth index.

var shoppingList = ["toothpaste", "bread", "eggs"]
var cart = shoppingList[1]

Happy coding!
