small question about day 39. heres the code that i have an issue with:

let data = Data(input.utf8)
let decoder = JSONDecoder()
if let user = try? decoder.decode(User.self, from: data) {
    print(user.address.street)
}

1) what does Data(input.utf8) mean? does it transform json into utf8? 2) i forgot what decoder parameters were exactly, is User.self specifying where we want to put the decoded data into? and is data what we are decoding?

Thank you very much, this forum is amazing.

1) .utf8 the encoding of the input Data (i.e. how to read it) 2) User is the struct that decoder will use in order to decode the data

Your struct (User in this case) should match the json you are decoding in order to succesfully return the results.
