title: Decoding Nested JSON Elements (SwiftUI)
body: <p>I am trying to parse the JSON data below into the structs that are shown.  I am having a helluva time trying to figure out how to get at the "nested" elements, such as elements "title:", "content:", and "excerpt:".    Whenever the code runs, it barfs while parsing the nested elements.</p>
  
  <p>I've looked at the Apple Developer stuff and reviewed the Playground here:  <a href="https://developer.apple.com/documentation/foundation/archives_and_serialization/using_json_with_custom_types" rel="nofollow noreferrer">https://developer.apple.com/documentation/foundation/archives_and_serialization/using_json_with_custom_types</a></p>
  
  <p>I also tried using quicktype.io to create the data models from the sample JSON, however, in the header of the exported file from quicktype it has the line: "let blogItem = try? newJSONDecoder().decode(BlogItem.self, from: jsonData)", however, I get a compile error that jsonData is not recognized and I'm not able to find any reference to it.</p>
  
  <pre><code>struct BlogSection: Codable, Identifiable {
      var id: Int
      var slug: String
      var link: String
      var title: [BlogTitle]
      var content: [ContentData]
  }
  
  struct BlogTitle:  Codable, Equatable, Identifiable {
      var id: UUID
      var rendered: String
  }
  
  struct ContentData: Codable, Identifiable{
      var id: UUID
      var rendered: String
  
  }
