Using the if-let statement, assign the value from the search function to a constant named result. If the name was found,

please help, I'm stuck and don't know 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 name

           }





        }

    return nil 
}

if let person = search(name: "Doc")  {
println (" \(found) was Found")


}
