How to parse single value from web URL of JSON array as Text in SwiftUI

I want to parse single value of email from array. I can able to parse image_url, app_name and app_title but don't know how to parse array of value as Text.

I have sample web JSON as show below.

{
  "image_url": "file:///Users/developer/Desktop/ios_icon.png",
  "app_name": “Developer - iOS App",
  "app_title": “Coding is my life”,
  “developer”: [
    {
      "email": “iosapps@gmail.com",
      "web”: "https://iosapps.wordpress.com",
      "about”: "https://iosapps.wordpress.com/about/“
    }
  ]
}

Here is my tried code:

import SwiftUI

struct JSONParser: View {
    @State private var jsonData: JSONData?
    
    var body: some View {
        VStack(spacing: 20) {
            Spacer()
            VStack {
                ZStack {
                    Circle()
                        .foregroundColor(Color("colorThirdaryLight").opacity(0.1))
                        .frame(width: 120, height: 120)
                        .shadow(radius: 4)
                    AsyncImage(url: URL(string: jsonData?.imageUrl ?? "")) { image in
                        image
                            .resizable()
                            .aspectRatio(contentMode: .fit)
                            .clipShape(Circle())
                            .padding()
                    } placeholder: {
                        Circle()
                            .foregroundColor(.secondary)
                    }
                    .frame(width: 120, height: 120)
                }
                Text(jsonData?.appName ?? "")
                    .bold()
                    .font(.title3)
                    .padding()
                Text(jsonData?.appTitle ?? "")
                    .font(.footnote)
                    .multilineTextAlignment(.center)
                Text("\(String(describing: jsonData?.developer))")
                    .font(.footnote)
                    .multilineTextAlignment(.center)
                    .padding(.top)
            }
            .padding()
            .background(Color(red: 242/255, green: 242/255, blue: 247/255))
            .cornerRadius(16)
            Spacer()
        }
        .padding()
        .task {
            do {
                jsonData = try await getJSONData()
            } catch GHError.invalidURL {
                Toast.regular(msg: "URL is invalid!")
            } catch GHError.invalidResponse {
                Toast.regular(msg: "Invalid response!")
            } catch GHError.invalidData {
                Toast.regular(msg: "Invalid data!")
            } catch {
                Toast.regular(msg: "Unexpected error!")
            }
        }
    }
    
    func getJSONData() async throws -> JSONData {
        let endPoint = "https:jsonparse.com/xxxxxxxxxxxx"
        
        guard let url = URL(string: endPoint) else {
            throw GHError.invalidURL
        }
        
        let (data, response) = try await URLSession.shared.data(from: url)
        
        guard let response = response as? HTTPURLResponse, response.statusCode == 200 else {
            throw GHError.invalidResponse
        }
        
        do {
            let decoder = JSONDecoder()
            let json = try decoder.decode(JSONData.self, from: data)
            return json
        } catch {
            throw GHError.invalidData
        }
    }
}

struct JSONParser_Previews: PreviewProvider {
    static var previews: some View {
        JSONParser()
    }
}

struct JSONData: Codable {
    let imageUrl: String
    let appName: String
    let appTitle: String
    let developer: [Developer]
    
    enum CodingKeys: String, CodingKey {
        case imageUrl = "image_url"
        case appName = "app_name"
        case appTitle = "app_title"
        case developer = "developer"
    }
}
extension JSONData {
    init(from decoder: Decoder) throws {
    let values = try decoder.container(keyedBy: CodingKeys.self)
      imageUrl = try values.decode(String.self, forKey: .imageUrl)
      appName = try values.decode(String.self, forKey: .appName)
      appTitle = try values.decode(String.self, forKey: .appTitle)
      developer = try values.decode([Developer].self, forKey: .developer)
  }
}
struct Developer: Codable {
    let email: String
    
    enum CodingKeys: String, CodingKey {
        case email = "email"
    }
}
extension Developer {
  init(from decoder: Decoder) throws {
    let values = try decoder.container(keyedBy: CodingKeys.self)
    email = try values.decode(String.self, forKey: .email)
  }
}

enum GHError: Error {
    case invalidURL
    case invalidResponse
    case invalidData
}

Last Text("\(String(describing: jsonData?.developer))") parsing as below.

optional([App.Developer(email: "iosapps@gmail.com")])

I want to parse only mail ID from JSON array.

Please Let me know how can I achieve it. Thank in advance..
