Insert a new item titled "Learn iOS" at the second position of the 'todo' array

So far in the array it looks something like this ["Learn Swift","Debug App","Fix Bugs"]

my job now is to insert Learn iOS

this is how my code looks insert("Learn iOS", AtIndex::(1)

arrays.swift 
var todo = ["Learn Swift", "Build App", "Deploy App"]
todo.append("Debug App")
todo.append("Fix Bugs")
todo.removeAtIndex(2)
let item = (2)
insert("Learn iOS", Atindex: 1)

Your code to insert "Learn iOS" as the second element is correct. What error are you seeing?

The code for the stage before looks wrong, though ... my attempt at this looked like:

var todo = ["Learn Swift", "Build App", "Deploy App"]
todo.append("Debug App")
todo.append("Fix Bugs")
let item = todo.removeAtIndex(2)
todo.insert("Learn iOS", atIndex: 1)

Maybe because i forgot to specify "todo,insert", instead of just insert("")
