I am trying to do the challenge where it asks me to assign the result to a variable preceded with if let. The error comes from the site which asks me if I have used println() again?

can someone please tell me what am I supposed to do here?

Thank you

func search(#name: String) -> String? {
    let names = ["Doc","Grumpy","Happy","Sleepy","Bashful","Sneezy","Dopey"]
    for n in names {
        if n == name {
            return n
    return nil

if let result = search(name: "doc"){

Hi Abdullah,

You're very, very close. Just make sure to capitalize the string you're passing in to search (in this case, "Doc").

Aw that was only it. Thank you!
