Hey! It seems like the focus state is not working. I even tried copying the example from the documentation directly into a new view and it didn't select the different textFields. Anybody that can see anything that I am missing? struct LoginForm: View {     enum Field: Hashable {         case username         case password     }     @State private var username = ""     @State private var password = ""     @FocusState private var focusedField: Field?     var body: some View {         Form {             TextField("Username", text: $username)                 .focused($focusedField, equals: .username)             SecureField("Password", text: $password)                 .focused($focusedField, equals: .password)             Button("Sign In") {                 if username.isEmpty {                     focusedField = .username                 } else if password.isEmpty {                     focusedField = .password                 } else {                 }             }         }     } }
