How can I fetch value from CoreData to Variable?

CoreData:

Item

• userName
• userSurname

Fetch request

@FetchRequest(
        sortDescriptors: [NSSortDescriptor(keyPath: \Item.timestamp, ascending: true)],
        animation: .default)
    private var items: FetchedResults<Item>

How can I apply last added userName in Items value to var X ?

Thanks to @vadian

var x = items.last?.userName ?? ""
