323 PointsWhy wouldn't this work the same? let item = "Test" todo.insert(newElement: item, atIndex: 2)
Challenge Task 2 of 3 for Collections: Now that we have to fix bugs in our app we cannot deploy it. Please remove the third item ("Deploy App") and assign it to a constant named item.
var todo = ["Learn Swift", "Build App", "Deploy App"]
todo.append("Debug App")
todo.append("Fix Bugs")
let item = "Test"
todo.insert(newElement: item, atIndex: 2)
Why wouldn't this work?
var todo = ["Learn Swift", "Build App", "Deploy App"]

42,016 Pointsthe 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)
