I can't tell what's missing from my code here, and the only error message is "Try Again!" What should I do?

It doesn't tell me what's wrong with my code.

months.swift 
let months = [1, 2, 3]

for index in months {
  if months == [1] {
    println("January")
  } else if months == [2] {
    println("February")
  } else if months == [3] {
    println("March")
  }
  println(months[index])
}

First, change months to index in your if statements. The variable index will take on each value of the array as the for in statement loops over the array months. Second, remove the brackets around the numbers 1, 2, and 3 in your if statements. You do not need the brackets since index is taking the an int value from the months array and [1] is an array itself and not an int. Finally, remove the last println statement println(months[index]).
