Challenge Task 2 of 2 (Optionals)
Question: Using the if-let statement, assign the value from the search function to a constant named result. If the name was found, use println to print out the string "Found". When calling the search function, pass it the name "Doc".
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)")
}
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)")
}

As you are using the "#" symbol in the search function, this tells Swift to use that name as both the local parameter name and the external parameter name so if you call this method you have to put the argument name like this:
if let result = search(name:"Doc"){ }
Furthermore, this challenge is requiring you to output "Found" instead of "Found (result)".
Hope that helps!
