It says I have the wrong Value?

The Preview has nothing.

arrays.swift 
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)

Hi Kyle,

Your code is correct except for when you're removing the third item from the array, currently you have removeAtIndex;2 which is invalid syntax as the number 2 needs to be wrapped within parentheses.

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)

Happy coding!
