Hi Brooks,

This challenge can be a bit tricky especially with how the previous video is explained, however. The only issue with the code you have above is you've called removeAtIndex twice when it only needs to be called once. As the challenge asks, it requires you to remove the item Deploy App from the array which would actually be index 2 as array's always start from an index of zero.

var todo = ["Learn Swift", "Build App", "Deploy App"]
todo += ["Debug App", "Fix Bugs"]
let item = todo.removeAtIndex(2)
todo.insert("Learn iOS", atIndex:1)

Aside from that you were pretty close.

Happy coding!
