iOS Swift Basics (retired) Collections Modifying an Array

How do I properly "removeLast" and "removeAtIndex", etc? I am having trouble understanding the objective here.

I can’t seem to figure out what Im doing wrong here. I have basically coped line for line what the guy in the video did but I keep getting error messages like...

"You need to call the 'removeAtIndex' method on the array.”

and when I add it, I get more error messages.

Any help is much appreciated. I can usually reverse engineer things if I have the correct answer.

arrays.swift 
var todo = ["Learn Swift", "Build App", "Deploy App"]

todo.append("Debug App")

todo.append("Fix Bugs")

let item = todo.removeLast("Deploy App")

todo.removeAtIndex(2)

.removeLast() likely doesn't take a parameter, since it removes the last one :) Simply remove the string parameter from it and see if it works.
