modifiying an array 2

The challenge tells me I need to add a new item into the array, but when I try to call the insert method, it states that I am not calling the method. I can't seem to figure this out and I'm pretty sure its probably something simple that I am missing.

arrays.swift
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")

insert requires a second parameter, atIndex. There's no way for the compiler to tell at which index your element should be inserted if we don't specify it.

todo.insert("Learn iOS", atIndex: 1)

Hope that helps :)
