I checked my code in XCODE and it was working fine for this activity but am I doing something wrong?

var todo = ["Learn Swift", "Build App", "Deploy App"] todo.append("Debug App") todo.append("Fix Bugs") todo.removeAtIndex(2) let item = todo.removeAtIndex(2) todo.insert ("Learn iOS", atIndex: 1)

arrays.swift 
var todo = ["Learn Swift", "Build App", "Deploy App"]
todo.append("Debug App")
todo.append("Fix Bugs")
todo.removeAtIndex(2)
let item = todo.removeAtIndex(2)
todo.insert ("Learn iOS", atIndex: 1)

I don't know what to say. I just tried it again and it passed. Double check you have your answer exactly like this:

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)

Everything is fine with one exception. You need to eliminate the fourth line - todo.removeAtIndex(2).

var todo = ["Learn Swift", "Build App", "Deploy App"]
todo.append("Debug App")
todo.append("Fix Bugs")
// todo.removeAtIndex(2) needs to be removed 
let item = todo.removeAtIndex(2)
todo.insert ("Learn iOS", atIndex: 1)

Still says "Your todo has a wrong variable in it" :\
