Still having trouble with this Challenge. They were looking for [January, February, March] but instead, my print reads as [January 1, February 2, March]
where does the 1 & 2 in my print come from and how to resolve it?
I'm sorry for the re-post of this. just desperately need the help.
Thank you!
let months = [1, 2, 3]
for month in months {
if month == 1 {
println("January")
} ; if month == 2 {
println("February") }
if month == 3 {
println ("March") }
else {
println(month)
}
}

It helps if you format your code with the normal indentation. I don't know if XCode Playgrounds have an autoformatter, but I did it manually for your code:
let months = [1, 2, 3]
for month in months {
if month == 1 {
println("January")
}
if month == 2 {
println("February")
}
if month == 3 {
println ("March")
} else {
println(month)
}
}
The extra numbers are coming from the final else clause. Remove that and you should be good to go.
The way I formatted it, it might be clearer that the else only applies to the last if condition, not the first two. If you wanted to chain together all of the if statements so that the final else did apply to them all, you'd need to use several else ifs:
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)
}
}
