Issue displaying array data inside UIAlert View

Essentially I would like to parse the JSON received from a url and display the data inside of alert popup.

I am able to do this with a simple array below but don't know how this can be done with an JSON array from a URL.

Currently working:

let jsonObj:[String: Any] = ["error": [                  "email": ["The email has already been taken."],                  "phone": ["The phone has already been taken."]]                  ]  if let errorMsgs = jsonObj["error"] as? [String: [String]] {      let errMsg = errorMsgs.values.map { $0.reduce("", +) }.joined(separator: "\n")      print(errMsg)      self.presentAlert(withTitle: "Try again", message: errMsg)        }  

JSON Array:

var structure = [Struct]()  private func fetchJSON() {          guard let url = URL(string: "url.com")              else { return }          var request = URLRequest(url: url)          request.httpMethod = "POST"          request.httpBody = "code=\(codeValue)".data(using: .utf8)          URLSession.shared.dataTask(with: request) { data, _, error in              guard let data = data else { return }              do {                  self.structure = try JSONDecoder().decode([Struct].self,from:data)              }              catch {                  print(error)              }              }.resume()      }        struct Struct: Decodable {          let id: Int          let reasons: String      }  

Sample JSON Array:

[    {      "id": 1,      "reasons": "Test"    },    {      "id": 3,      "reasons": "Test"    }  ]  

How can I get the reasons string from the array to populate in the alert similar to above.
