13,515 PointsYou need to add an else clause when returning nil. You also need to add the parameter "name" as when calling the search method, which is the "argument" that you are missing.
It should look like this after both stages:
func search(#name: String) -> String? {
let names = ["Doc","Grumpy","Happy","Sleepy","Bashful","Sneezy","Dopey"]
for n in names {
if n == name {
return n
} else {
return nil
}
}
return ""
}
if let result = search(name: "Doc") {
println("Found")
}
