Help, i can not use a for- in loop in conjunction with an if statement.

How do i use a for- in loop in conjunction with an statement

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

you could just use a switch statement

let months = [1 , 2 ,3]

for month in months {
case 1: 
println("January")
case 2:
println("February")
default:
println("March")

}

This may be a late answer for you, but in order for you to use the for in loop, you have to use the .hashValue. 

let months = [1,2,3]

for month in months {
    if month.hashValue == 1 {
        println("January")
    } else if month.hashValue == 2 {
        println("February")
    } else if month.hashValue == 3 {
        println("March")
    } else {
        println("There are only 3 months in this loop")
    }
}
