Can't seem to figure it out?

Can someone explain it more to me?

Thanks,

months.swift 
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"]
} else {
println[month]
}
}

You are very close. Your first issue is that you have incorrectly written your println functions by using brackets instead of parenthesis. i.e. println["January"] instead of println("January"). Then, you can delete that final else clause because it is unnecessary. The code should end after println("March") }.

no problem. So the final solution should be this. See if yours matches.

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")
    }
}
