It asked you to insert at the second position, which is at index 1 because the indexes start at 0. Also, you don't need to assign it to a variable. This is what passed.

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

todo.insert("Learn iOS", atIndex: 1)
