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 nil
}

Your return type of String
needs to be an optional, this can be accomplished by simply adding a question mark to the end of the type.
func search(#name: String) -> String? {
// ...
}
Happy coding!
