my answer for task 3 keeps showing that I have the wrong value for my todo variable.

I have examined and re-examined your lesson video and I dont understand what I am doing wrong, any advice?

Ethan Hockridge

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

The problem is you made a slight error in Task 2 and Treehouse didn't catch it.

The array method removeAtIndex() takes an integer parameter: the index of the item you want to remove. What does this method do when you don't supply an index?
