Challenge Question 2 of 3: - arrays.swift

Getting this error message - Bummer! item should have the value "Deploy App" but is Debug App

My answer below: var todo = ["Learn Swift", "Build App", "Deploy App"] todo.append("Debug App") todo.append("Fix Bugs") todo.removeAtIndex(2) let item = todo.removeAtIndex(2)

What am I doing wrong.

when you remove a value then call it in a constant the constant will point to the wrong value so remove the

todo.removeAtIndex(2) hope it works

Frederick, Agree with Ramiro. You were close. Just delete your penultimate line - todo.removeAtIndex(2) Your final line combines the two - let item = todo.removeAtIndex(2) . The way you wrote it, the third item was already removed before you assigned "item" to the third item, which was no longer "Deploy App", but was now "Debug App."
