What does it mean your 'todo' array has the wrong value in it?

I added to my Array "learn ios" in the second position and its telling me i did it wrong. ex: todo.insert("Learn ios", atIndex: 1)

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", atIndex: 1)

You might just be able to insert a new string to a index which is empty. As I can see in your code your Index[2] might be empty because you called the "removeAtIndex(2)" method. Try to insert it into the Index 2 instead of Index 1 as you did in your Insert Method

Perhaps because it is supposed to be iOS not 'ios'. This is the answer.

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)
