iOS Swift Basics Collections Modifying an Array

I have no idea what's wrong in it.

Question is not that clear to me.

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:2)

Hey there,

good job so far! There are only two small problems in your insert method. Firstly you have to separate the arguments with a comma instead of a colon. The other problem is that you have to insert "Learn iOS" at the second position, which means that you have to insert it at the index 1 because the index of arrays starts at 0.

Like so:

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)

I hope that helps! :)
