Error isn't helpful

Bummer! You didn't println the right values. You printed [January, Febuary, March] and we were looking for [January, February, March].

What is wrong here in my code?

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

for var i = 0; i < months.count; i++ {
    if i == 0 {
        println("January")
    } else if i == 1 {
        println("Febuary")
    } else if i == 2 {
        println("March")
    }
}

The task states

Using a for-in loop and an if statement, print out "January" when you encounter a 1, "February" when you encounter a 2, and finally "March" when you encounter a 3.

you did not use a for in loop, you used a traditional for loop. change your code to use a for in loop. you also need to start the loop at 1, not 0, since your numbers in the array start at 1.

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

Ah, I see (for-in loop missing).

Also, I wasn't spelling "February" correctly. :/

Thanks, Stone!
