This code works in play ground but does not seem to satisfy the challenge. Please help...

At first I nested the fi let statements, but then I simply added to the existing if let and in the playground it worked. However, I have not satisfied the challenge.

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


search (name: "Doc")

Hi Alex,

Your code is correct except that it does not answer the code challenge.

They are looking for something very specific.

See below.

func search(name 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") { // use if let
    println("Found") // print "Found" if found
}

I hope that helps,

Mike
