Hey all, I'm kinda stuck on this question. This questions asked to modify the codes into an optional and to return a nil if the name is not found in the array.
Here are my codes :
func search (name: String) -> String? {
let names = ["Doc","Grumpy","Happy","Sleepy","Bashful","Sneezy","Dopey"]
for n in names {
if (n == name) {
return name
}
}
return nil
}
I've ran the codes on XCode and it was fine. Im not sure what's wrong.
func search (name: String) -> String? {
let names = ["Doc","Grumpy","Happy","Sleepy","Bashful","Sneezy","Dopey"]
for n in names {
if (n == name) {
return name
}
}
return nil
}

It appears you've accidentally altered the argument name which should be named aka it should have a pound # in-front of it.
func search(#name: String) -> String?
Happy coding!

I think the problem is in where you have written your "return nil" code, as you should not touch the default return "" line, while you dealt correctly with the optional.
I give you this hint:
We have a situation where we want to return the name IF it exist, if it does not exist (ELSE) we want to return nil.
