iOS Swift Functions and Optionals Optionals What is an Optional?

Somehow the code works correctly on my Xcode but doesn't on this framework.

Is there a problem when compiling the code, it seems to work right on my Xcode.

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

    return nil

if let result = search(name: "Doc"){
    println("Found \(result)")

Hi Emir,

The challenge just wants the string "Found" to be printed out if the test passes (rather than "Found" and the name itself.)

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

Hope this helps!

That works! Thank you very much.
