Moving UserDefaults to an array

Question

I'm running into an issue while attempting to move a user defaults array into a second array so I may be able to load it into a table view.

my userdefault is just a single field of type Int. I'm able to store data in the UD and when I display it it shows optional values: [176, 177]

I have the following declared at the top level of my view:

let defaults = UserDefaults.standard
   
var intArray = [[Int:Any]]()

In viewDidLoad I have the following:

override func viewDidLoad() {
        super.viewDidLoad()
      intArray = defaults.array(forKey: "Favorites") as? [[Int: Any]] ?? []
      print(defaults.array(forKey: "Favorites"))
   }

The intArray is always empty but when I print the Favorites UserDefault it shows as it does above.

Obviously, I'm doing something wrong here; any help would be greatly appreciated.

Right now, you're trying to decode an array of Dictionaries with Int as a key and Any as a value (the outer set of brackets is the array, the inner brackets with the : is the Dictionary).

If you replace all occurrences of [[Int:Array]] with [Int], your code will work.
