Hi, I am trying to do the challenge and it keeps on saying, "Bummer1 You need to define team let. Help me please!

Why would it want me to define item when I do not have it?

~thanks

arrays.swift 
var todo = ["Learn Swift", "Build App", "Deploy App"]
todo += ["Debug App", "Fix Bugs"]
todo.insert("Learn iOS", atIndex: 1)

the task states: Please remove the third item ("Deploy App") and assign it to a constant named item.

according to the documentation, swift arrays have a method called removeAtIndex:

removeAtIndex(_:)

Removes the element at the given index and returns it.

so we can remove the item and assign that item that was removed to a constant in one step:

var todo = ["Learn Swift", "Build App", "Deploy App"]
todo.append("Debug App")
todo.append("Fix Bugs")
let item = todo.removeAtIndex(2)
