im trying to dispaly array object come from api response as [[String: Any]] at table view
and thats my struct

class CategoriesDep: NSObject {



    var depName: String

    var depImage: String

    var subName = [subData]()



    init?(dict: [String: JSON]) {



        guard let image = dict["main_department_image"]?.imagePath, !image.isEmpty else { return nil }



        self.depImage = image

        self.depName = (dict["main_department_name"]?.string)!









    }



    struct subData {

        var dep: String

        init(dic: [String: Any]) {

            self.dep = dic["sub_department_name"] as! String



        }

    }

}

Please check below code to parse your json

class CategoriesDep: NSObject {

    var depName: String

    var depImage: String

    var subName = [subData]()



    init?(dict: [String: Any]) {



        guard let image = dict["main_department_image"] as? String, !image.isEmpty else { return nil }



        self.depImage = image

        self.depName = (dict["main_department_name"] as? String)!

        subName = 

        for subDict in (dict["sub_depart"] as? [[String:Any]] ?? ){

            subName.append(subData(dic: subDict))

        }



    }



}

struct subData {

     var dep: String

     var image :String

     var id : String

     init(dic: [String: Any]) {

          self.dep = dic["sub_department_name"] as! String

          self.image = dic["sub_department_image"] as! String

          self.id = dic["sub_department_id"] as! String

     }

}

and if you want to access subdata struct out side of CategoriesDep class then declare structure outside CategoriesDep class

Parse your given json Respoise like

       let json =  [

            [ "sub_depart" : [

                [ "sub_department_name" : "hos", "sub_department_id" : "6", "sub_department_image" : "23.jpg"

                ]

                ],

              "main_department_id" : "2",

              "main_department_name" : "main ",

              "main_department_image" : "14.jpg"

            ],

            ]

        var catDepart : [CategoriesDep] = 

        for dict in json {

            catDepart.append(CategoriesDep(dict: dict)!)

        }

        print(catDepart[0].subName[0].dep)

You could use Codabel protocol to be more swifty ;) and cleaning up the code.

let jsonString = "[{"sub_depart" : [ {"sub_department_name" : "hos", "sub_department_id" : "6", "sub_department_image" : "23.jpg" } ], "main_department_id" : "2", "main_department_name" : "main ", "main_department_image" : "14.jpg"}]"



struct CategoriesDep: Codable {



    let mainDepartmentName: String

    let mainDepartmentImage: String

    let mainDepartmentId: String

    var subDepart: [SubData] = 

}



struct SubData: Codable {



    let subDepartmentName: String

    let subDepartmentImage: String

    let subDepartmentId: String

}







if let jsonData = jsonString.data(using: .utf8) {



    let decoder = JSONDecoder()

    decoder.keyDecodingStrategy = .convertFromSnakeCase

    var departments: [CategoriesDep]? = try? decoder.decode([CategoriesDep].self, from: jsonData)



    ...



}

Note the decoder.keyDecodingStrategy = .convertFromSnakeCase here which is mapping the underscore (snake_case) API property names to your camelCase ones.

If you need different property names you have to implement CodingKeys enum to map them.
