iOS Swift Basics (retired) Collections Modifying an Array

The answer in this challenge is not correct. Index location for "Deploy App" is 2 not 1. Only accepts 1. Pls correct.

I checked this on Xcode.

arrays.swift 
var todo = ["Learn Swift", "Build App", "Deploy App"]
todo += ["Debug App","Fix Bugs"]
todo.removeAtIndex(1)
let item = todo.removeAtIndex(1)

Hi Greg,

As explained in the video the removeAtIndex method removes the given value index from the Array therefore we can't call it twice as we would be removing the values Build App and Deploy App, instead you just need to call it once and use the index number of 2 since Deploy App is the 3rd item in the array.

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

Happy coding!

Thanks Chris! I see that now. This and the next challenge had me so confused. Then I realized I was removing the value twice and thought, "I'm and idiot." That's why the call it learning, huh. Thanks again.

Indeed, the learning process never ends.
