Print 2 joined arrays in alphabetical order and in descending order

[timswift]

Right now my code prints its string array in alphabetical order. What I would like to do is is organize the array in a way like [a,1],[a,2],[b,4). Alphabetical order then in the int descending order. Right now you can see in my photo bellow what the code bellow is doing.

  var yourArray = [String]()
var number = [Int]()

class ViewController: UIViewController {

    @IBOutlet var labez: UILabel!
    @IBOutlet var textA: UITextField!
    @IBOutlet var textB: UITextField!

    @IBAction func store(_ sender: Any) {
        yourArray.append((textA.text!))
        number.append(Int(textB.text!)!)



        let d = yourArray.enumerated().map { (index,string) -> String in
            guard  number.count > index else { return "" }
            return "\(string )\(" ")\(number[index]) "
        }


        let sortedArray:[String] = d.sorted { $0.localizedCaseInsensitiveCompare($1) == ComparisonResult.orderedAscending }


        labez.text = sortedArray.map { " \($0)" }.joined(separator:"\n")

    }

      !string.isEmpty,
      let numberString = numberTextField.text,

    let newitem = Item(string: string, number: number)
    itemArray.append(newitem)
    
    let sortedArray = itemArray.sorted()
    
    let output = sortedArray.reduce("") { (result: String, item: Item) -> String in
      return "\(result)\n\(item.string) \(item.number)"
    }

    outputLabel.text = output
  }
