How can I save an array to UserDefaults, and then retrieve that array and print

Question

Here is my code. It seems an error. Can anyone please help.

class PopUpVC: UIViewController {
  var myArray1 = ["1","2","3"]
  var myArray2 = [String]()
  UserDefaults.standard.set(myArray1, forKey: "array")

  override func viewDidLoad() {
    super.viewDidLoad()
    self.myArray2 = (UserDefaults.standard.string(forKey: "array") as? [String])!
    print(self.myArray)
  }

That answer is just wrong. You don't retrieve an Array of Strings using `Userdefaults.string(forKey:)`, you do it using `array(forKey:)` or `object(forKey:)`, then cast it to `[String]`. Have you even tested that code? It wouldn't even compile, since you are trying to give a `[String]` default value to a `String?` variable. – Dávid Pásztor Aug 30 '17 at 10:14
i have used is not `String(forKey:)` I used is `StringArray(forKey:)` – Gregory Wilson Pullyattu Aug 31 '17 at 11:29
Yeah that's correct i was accepted your edit. – Krishnarjun Banoth Aug 31 '17 at 12:07
