Swift if statement: I think I know what I am doing, but the quiz does not agree.

The quiz question is :

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 is 

let months = [1, 2, 3]    

for month in months{
    if( month == 1)
    {
    println("Januaray")

    }
    else if( month == 2)
    {
        println("February")

    }
    else if( month == 3)
    {
        println("March")

    }
}

The error reported is Bummer! You need to use an if statement.

Please note I used just if statements in stead of if else as noted above, with the same error.

What am I doing wrong?

Hi Brian,

It looks like you have "Januaray" when it should be "January". Also, Swift doesn't allow you to have parenthesis with your if statements.

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

    }
    else if month == 2
    {
        println("February")

    }
    else if month == 3
    {
        println("March")

    }
}

I guess the fact it was saying I am missing a if statement is what confused me.

let months = [1, 2, 3] 

for month in months{
    if( month == 1)
    {
    println("January")    

    }
    else if( month == 2)
    {
        println("February")    

    }
    else if( month == 3)
    {
        println("March")    

    }
}

Error " Bummer! You need to use an if statement."

I am going to edit my original answer to reflect this, but Swift is evidently very picky with if statements. You cannot use parenthesis with your if statements. Once I changed that (and January of course), I passed the challenge.
