what can make a value of my todo variable wrong

I am failing to insert an item on my todo list variable

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", atIndex :1)

You are removing the item at index 1 two times. Also, it is the third item in the array that needs to be removed(index 2). It should just look like this: 

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)
