Since you appended two additional items, Debug App and Fix Bugs, your array now looks like this

[0] -> "Learn Swift"
[1] -> "Build App"
[2] -> "Deploy App"
[3] -> "Debug App"
[4] -> "Fix Bugs"

Because it wants you to remove "Deploy App", you can't use removeLast, because "Fix Bugs" is the last value. You should use the method "removeAtIndex" instead.
