The search function below returns a name if it is found in the array and an empty string if it is not found. Modify the search function to return an optional instead of just a String. In addition, you have to make sure the function returns a nil if the name is not found in the array.
func search(#name: String) -> String? {
let names = ["Doc","Grumpy","Happy","Sleepy","Bashful","Sneezy","Dopey"]
for n in names {
if n == name {
return n
}
}
return ""
}
if let se = search(name:"Doc")
{
println("true")
}
