I am trying to access the property of a struct within a struct, and I'm sure I'm doing something wrong. E.g.: customers.address.address_line_1. I'm trying to do it this way because it's the model for a JSON response, and address is nested in the response.

struct arrayOfCustomers: Codable {
    var customers: [Customer]
}

struct Customer: Codable, Identifiable  {
    var id: String
    var created_at: String
    var updated_at: String
    var given_name, family_name, email_address, phone_number: String?

    struct Address: Codable {
      var address_line_1, locality, administrative_district_level_1, postalCode: String?
      var country: String?
  }
}

Example of the response:

{
  "customers": [
    {
      "id": "MJAG403GV96BX367R56N4FZJTG",
      "created_at": "2021-11-07T04:18:21.42Z",
      "updated_at": "2021-11-07T23:10:20Z",
      "given_name": "Test",
      "family_name": "Customer",
      "email_address": "email@email.com",
      "address": {
        "address_line_1": "123 Any St",
        "locality": "Somewhere",
        "administrative_district_level_1": "CA",
        "postal_code": "55555"
      },
      "phone_number": "+12025551234",
      "preferences": {
        "email_unsubscribed": false
      },
      "creation_source": "DIRECTORY",
      "segment_ids": [
        "MLPYEYRXNK0KW.REACHABLE"
      ],
      "version": 1
    }
  ]
}

Thank you! That did it.
