Control Flow, If Statement Challenge (Swift)

Question

Hey guys, I am stuck on this challenge and have no clue on what to do to fix the code. Can anyone help, please?

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.

My code:

let months = [1, 2, 3]

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

Thanks in advance!

you are missing the variable name on your else if statement comparison. you have else if == 2 but you need to have else if month == 2.

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

if you get compiler errors in the challenge, click the preview button and see what the error message says. Most of the time its pretty helpful. In this case it showed:

swift_lint.swift:11:15: error: unary operator cannot be separated from its operand
    } else if == 2 {

which told me exactly where the error was.
