I don't know what I'm doing wrong here. I watched the video 3 times and still am at a blank with this Challenge Task 2 of 2.
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
}
if let result = search("Doc") {
println("Found \(result)")
}

39,021 PointsMake sure you click on the "Preview" button when you get an error. Swift errors are occasionally actually helpful! In this case it's very clear what's wrong. Try submitting your exact same code again and check out the compiler error.
Also, looking at challenge 2 of 2, you're just supposed to return "Found". Not "Found Doc".
Edit: per Chris Upjohn's suggestion, here's the solution:
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
}
if let result = search(name: "Doc") {
println("Found")
}
