Use Userdueflts on a struct

[timswift]

My code below uses a struct to organize the data. However when I go to the next view controller and return to the original one all of the data is deleted. How can I use user defaults to save the data to the label.

             import UIKit
class ViewController: UIViewController {
@IBOutlet var c: UITextField!
@IBOutlet var a: UITextField!
    @IBOutlet var label: UILabel!
    var contacts = [Person]()
    
    @IBAction func save(_ sender: Any) {
        contacts.append(Person(name: a.text!,  phone: Int(c.text!)!))
        let sortedContacts = contacts.sorted {
            ($0.name, $0.phone) < ($1.name, $1.phone)
        }
        label.text = contacts.count == 0 ? "" : sortedContacts.map {$0.description}.joined(separator: "\n")
        
        Person.myStruct.append(label.text!);}

    struct Person {
        var name: String
        var phone: Int
        static var myStruct = [String]();
        var description: String {
            return   "\(name),\(phone)"
        }}}

Hi @timswift,
There are a couple of options for you, you can save the data into a DB or persist to a text file or when you present the new viewController ensure that the UI elements are not released.

It is not a very good idea to store data in the UI elements like UILabel, etc.

Lastly, code helps to see what you are doing

cheers,
