5,537 PointsThe problem with your code is that the variable "month" that you create inside the for loop by writing "for month in months" is not an incrementing count variable (meaning it starts at 0 and increases by one every loop) but is a variable that holds the value indexed inside the array every time the loop runs. This means that when the loop runs 1 time its value is 1, since the first value of the array is 1 (it would be 4, per say, if you would have written "let months = [4, 2, 3]", being 4 the first value), 2 when ran for the second time and 3 when ran for the third time. To solve this problem simply access the month variable every single time the loop is run and compare it to your chosen values instead of selecting the value inside the array. Try this code, it should do the job.
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")
}
}
