Array Challenge 3/3

I can't figure out why this is wrong it says the value in my todo variable is wrong. It asks me to insert "Learn iOS" in the second position of the array.

arrays.swift 
var todo = ["Learn Swift", "Build App", "Deploy App"]
todo += ["Debug App","Fix Bugs"]
todo.removeAtIndex(1)
let item = todo.removeAtIndex(1)
todo.insert("Learn iOS", atIndex: 3)

Hi Ibrahim Abdul-Karim,

You have a couple of problems which I've mentioned below.

  1. Your first called to removeAtIndex isn't needed as you're not assigning the value to anything
  2. Your second call to removeAtIndex should have a value of 2 as you need to remove the 3rd array value
  3. Your insert call should add the Learn iOS string at index 1 which is the second item in the array
var todo = ["Learn Swift", "Build App", "Deploy App"]
todo += ["Debug App","Fix Bugs"]
let item = todo.removeAtIndex(2)
todo.insert("Learn iOS", atIndex: 1)

Happy coding!
