if statement

You are provided with a constant array named months that contains 3 consecutive numbers starting at 1. 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.

i can't figure this challenge out :(

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

for month in months{
  println(month)
}

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

The last case of your if is invalid. If you want to add another condition you should use "else if" followed by the condition. If you want to add a "catch all remaining cases" you should use "else". You cannot use "else" with a condition.

Try this:

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

Hope this helps

While this will resolve the issue, this is also giving the impression that any month other than month 1 and 2 will equal march. Best to do the else if in this case.
