Hey guys, I can't figure out whats wrong in my code here for the task 2 of 2 in Swift Functions ans Optionals...
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 } return "" }
if let result = search("Doc") { println("Found") }

if let result = search(name: "Doc"){
println("Found");
}

And you're missing the label 'name' in the last line :)
If you put all of this in a Playground and click through the errors you'll get helpful hints.
I might also suggest that you rewrite the function in a 'cleaner' manner. Not being critical, just trying to help. You are obviously close to the right track here :)

Thanks guys. :)
It is written cleaner but when I copy/pasted it it seemed to all come out weird... sorry about that.
