Everything else seems fine but I'm unsure on how to write the code to check for an odd number.

let oddNumber = numberToCheck % 2 != 0
The above will evaluate to true or false.
Hope this helps you pass the challenge!

I think the easiest method is to use the Remainder Operator, %. You should be able to do something along the lines of:
if your_number % 2 == 0 {
// even number handling
} else {
// odd number handling
}
That will check to see if your_number is evenly divisible by two and, thus, is an even number.
Post back if you are still stuck or have further questions.
Happy coding,
Ken
