Hello, I have a problem with one task in Unwrap app.

"Write code that creates an array containing all the people with the first name Terry."

And I write something like this:

var names = ["Terry Jones", "John Terry", "Terry Crews", "Terry Farrell", "Samuel Terry"]
var terries = [String]()
for name in names {
    if name.hasPrefix("Terry") {
        terries.append(name)
    }
}

In playgorund my code works fine, but Free Coding in Unwrap won't accept this solution.

Where is my bad?

Thanks for help!

Try

var names = ["Terry Jones", "John Terry", "Terry Crews", "Terry Farrell", "Samuel Terry"]
var terries: [String] = [String]()
for name in names {
    if name.hasPrefix("Terry") {
        terries.append(name)
    }
}

It works! Thank you very much!!

But can you explain me why? and why my code is wrong?

Thanks.

Your is not wrong. It just that the "Unwrap" looks for certain "answers" and infering a type it does not do (at the moment).

To be honest. I had a look at the "Unwrap" code at the json file

Okay, Thanks again for help! problem solved :)
