Don't know what I'm doing bad here:
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
}
let result = ["Doc", "Grumpy", "Happy", "Sleepy", "Bashful", "Sneezy", "Dopey"]
if name = search("Doc") {
println("Found")
}

There is a couple of issues with your code, let's going through them.
- You have a named paramater aka
#name, whenever you have named parameters you have to refer to them in your method call - You have reassigned the array from the
searchmethod toresultand haven't used a properif-letstatement
Fixing Problem 1
As I said whenever you have named parameters you need to refer to them, in the case of the search method it's asking for the following.
search(name: "Doc")
Fixing Problem 2
First off you don't need to reassign the array to an result constant, instead you want to use an if-let statement which checks for the optional and executes code inside the if statement if the result isn't nil.
if let result = search(name: "Doc") {
println("Found")
}
By the end you should have the following.
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")
}
Happy coding =)

What are the benefits of using a named function?
