I keep getting the same message on this Challenge: "You need to call the 'Insert' method on the array." Nothing works?

Challenge: Insert a new item "Learn iOS" at the second position in the todo array.

Keeps saying I need to call the 'insert' method on the array. I try:

todo.insert("Learn iOS", atIndex: 2) I've done various number and syntax combinations. It doesn't seem to like them? Seems ok in the play ground.

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

todo.insert("Learn iOS",2)

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)

Try this

Hello Alain:

I've modified your code so that it can be properly displayed. Didn't change anything in your answer.

Good answer !

Hello David:

SO close, the only thing is that the second position has an index of 1. But you are doing a great job.

Remember, that arrays have indexes starting from 0. Meaning the first position will always be 0.

Good luck.
