I dont understand what i am doing wrong, could someone please advise?


func search(#name: String) -> String? {
    let names = ["Doc","Grumpy","Happy","Sleepy","Bashful","Sneezy","Dopey"]
    for n in names {
        if n == name {
            return n
if let notFound = n("Snow White") {
println("Found \(notFound)")

Since your second if-else loop is outside of your function you need to call the function again not the variable n.

Try this code:

if let notFound = search(name: "Snow White") { println("found") }

else { println("not found") }

Hope this helps!
