10,476 PointsFor the first part of this challenge they wanted you to make the function an optional and be able to return nil since thats the point of an optional
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 ""
}
Then they wanted you to use an if-let statement like such
if let result = search(name: "Doc") {
println ("Found")
}
