how to do this

I have no idea what I'm doing wrong

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 culprit = search(name:"Grumpy"){
    println("N Found: \(culprit)")
}
}

You have the placement of your curly braces wrong. You don't want that last bit, "if let culprit..." inside of your method.

It should look like this:

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 culprit = search(name:"Grumpy"){
  println("N Found: \(culprit)")
}
