Build a simple iphone app with Swift, creating a data model, challenge task 2 0f 2

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. My code:

var shoppingList = ["toothpaste", "bread", "eggs"]
var cart = shoppingList.removeAtIndex(1)

Bummer! You need to use subscripting to access the array element.

I can not figure out what is wrong in the last line of my code, it works in playground though. I would much appreciate a little help.

The method "removeAtIndex" will remove the string "bread" from the array and assign it to the variable "cart", which is not the task you are assigned. Read carefully: "retrieve the string". It is only asking you to retrieve the string with the use of subscripting.

So, to do this, you need to access the string you want with the use of array index.

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

Hope this helps.
