I can't figure out what is missing from my code for the Challenge. For some reason it is responding by "Cannot invoke == with an argument list of type ([Int], IntegerLiteral...
Can I get some help please and thank you.
let months = [1, 2, 3]
for month in months {
if months == 1 {println("January")
}
else if months == 2 {println("Febraury")
}
else if months == 3 {println("March")
}

You're very close, but take another look at what you're checking. The error message says you can't use == to compare [Int] to an integer (it says integer in a complicated way, but that's what it means). Note the square brackets in [Int]. That means you're trying to check to see if an array is equal to an integer.
As you iterate through the months array, you need to check if your working variable, month is equal to the integer in question.
let months = [1, 2, 3]
for month in months {
if month == 1 {
println("January")
}
// etc...
Note I also changed the formatting a bit - this is how you'll typically see people write blocks of code like this - it's more readable too.
Good luck!

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")
}
}
