Это файл Doc, созданный в Postman методом записи и URL «link/services.php». Это файл заголовка.

 @Headers({"Content-Type: application/json"})
        @POST("services.php")
        
Observable<Division> divisionListApi(@Body HashMap<String, String> map);
map.put("method", "My_List");
 

После Поколения Почтальонов Я Получил Это Ниже.

 {"err_code":9,
"message":"My List ",
"list":[
{"ForestDivision":"Yam(T)"},
{"ForestDivision":"Rewar(T)"},
{"ForestDivision":"Ro(T)"},
{"ForestDivision":"Bh(T)"},
{"ForestDivision":"Ka(T) "},
{"ForestDivision":"Ambal(T) "},
{"ForestDivision":"Fari(T)"}]
}
 

Я сделал запрос, отправив сообщение mehod, это правильный способ создания кода в
swiftui.

     import Foundation
    import  Combine
    
    struct  File: Decodable, Hashable {
        var error_code : Int
        var message : String
        var list : [lisst]
    }
    
    struct lisst: Decodable, Hashable {
        var ForestDivision: String
    }    
    
    class fetchResults : ObservableObject{
        
        @Published var fetchedRes : [lisst]?
    
    func getData(completion: @escaping (File) -> ()){
        print("Fetch")
    
        let parameters = "{ I dont Know }"
 

       let postData = parameters.data(using: .utf8)
        var request = URLRequest(url: URL(string: 
 "URl")!,timeoutInterval: Double.infinity)
    
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    
        request.httpMethod = "POST"
        request.httpBody = postData
    
        let task = URLSession.shared.dataTask(with: request) { (data, _, _) in
            let resultList = try! JSONDecoder().decode(File.self, from: data!)
                            print(" ")
                            print("ID: (resultList.error_code)")
                            print("VOLUME: (resultList.message)")
                            print("READINGS: (String(describing: resultList.list))")
                            print(" ")
            print("SUCCESS: Got data - (data! )")
            DispatchQueue.main.async {
                       completion(resultList)           // << here !!
                    }
        }
        task.resume()
    }
        
    }
 

Также как писать в представлении Swiftui.
Чтобы Правильно Работать в режиме списка.

     import SwiftUI
    import  UIKit
    
    struct DivisionList: View {    
        @ObservedObject var res = fetchResults()    
        var body: some View {    
            NavigationView {
                Text("Nothing Here")
                
                List(res.fetchedRes ?? [], id: .self) { resp in      // Error Here
                    ForEach(res.list, id: .self) { course in
                        VStack {
                            Text(res.for)                             // Error Here
                        }
                    }
                }                       
                .navigationBarTitle("Data")
                    .onAppear(perform: {
                        self.getData                                        // Error Here
                    })
            }
    
            }
        }    
    
    struct DivisionList_Previews: PreviewProvider {
        static var previews: some View {
            DivisionList()
        }
    }
