What exactly is it asking for?

Not sure what to do.

search.swift 
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 = ("Doc") {
   println("Found \(result)")
}

Almost there :

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
}
     // you had to call the function and give it a name in the parameter
if let result = search(name: "Doc") {
println("Found")
}
