so this is my response and now i will show you my model class

struct Jigyasa : Codable {
    let image3 : String?
    let image1 : String?
    let name_english : String?
    let images : String?
    let name_hindi : String?
    let jigyasa_id : String?
    let image5 : String?
    let image4 : String?
    let name_sanskrit : String?
    let image2 : String?

    init(image3: String?,image1: String?,name_english: String,images: String?,name_hindi: String?,jigyasa_id: String?,image5: String?,image4: String?,name_sanskrit: String?,image2: String?) {
        self.image3 = image3
        self.image1 = image1
        self.name_english = name_english
        self.images = images
        self.name_hindi = name_hindi
        self.jigyasa_id = jigyasa_id
        self.image5 = image5
        self.image4 = image4
        self.name_sanskrit = name_sanskrit
        self.image2 = image2
    }
}

and below is my code for fetch data and populating collectionView

var jigyasaData = [Jigyasa]()

func jigyasaCatList(){
    let preferences = UserDefaults.standard
    let uid = "u_id"
    let acTkn = "acc_tkn"

    let u_ID = preferences.object(forKey: uid)
    let A_Token = preferences.object(forKey: acTkn)

    let params = ["user_id": u_ID!, "access_token": A_Token!]
    print(params)
    Alamofire.request(apijigyasacategorylist, method: .post, parameters: params).responseJSON(completionHandler: {(response) in
        switch response.result{
        case.success(let value):
            let json  = JSON(value)
            print(json)
            self.jigyasaData.removeAll()
            let data = json["jigyasa_category_list"]
            if data == []{

            }else{
                data.array?.forEach({ (jList) in
                    let jigarray = jList["jigyasa"]
                    if jigarray == []{

                    }else{
                        jigarray.array?.forEach({ (jUData) in
                            let j_uData = Jigyasa(image3: jUData["image3"].stringValue, image1: jUData["image1"].stringValue, name_english: jUData["name_english"].stringValue, images: jUData["images"].stringValue, name_hindi: jUData["name_hindi"].stringValue, jigyasa_id: jUData["jigyasa_id"].stringValue, image5: jUData["image5"].stringValue, image4: jUData["image4"].stringValue, name_sanskrit: jUData["name_sanskrit"].stringValue, image2: jUData["image2"].stringValue)
                            self.jigyasaData.append(j_uData)
                        })
                    }
                    self.collView.reloadData()
                })
            }
        case.failure(let error):
            print(error.localizedDescription)
        }
    })
}


func numberOfSections(in collectionView: UICollectionView) -> Int {
        return 1
}

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return jigyasaData.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! JigyasaCollectionViewCell
    let photo = jigyasaData[indexPath.row].images
    let fileUrl = URL(string: photo!)
    cell.imgView.sd_setImage(with: fileUrl, placeholderImage: UIImage(named: "ic_PlaceHolder"), options: .refreshCached, completed: nil)
    cell.imgView.layer.cornerRadius = 10
    cell.lblTitle.text = jigyasaData[indexPath.row].name_hindi
    cell.imgView.layer.shadowColor = UIColor.gray.cgColor
    cell.imgView.layer.shadowOffset = CGSize(width: 0.0, height: 0.0)
    cell.imgView.layer.shadowRadius = 2.0
    cell.imgView.layer.shadowOpacity = 0.3
    return cell
}

now i will show you expected output and current output which i am getting from my code

![Currently i am getting output like this][]

![][And Now i want output like this]

someone please help me how to get images by section in collectionView

my previous question is for how to fetch data from json and now this question is for after getting data while populating collectionView i am facing issue so please help me i am stuck with this issue

Answer 1

I used your json file to in my empty file and I have parsed data.you can pass as this

Make Model as this

  import Foundation

  struct JigyasaModel: Codable {
  let jigyasaCategoryList: [JigyasaCategoryList]
  let message, success: String

 enum CodingKeys: String, CodingKey {
    case jigyasaCategoryList = "jigyasa_category_list"
    case message, success
}
}

// MARK: - JigyasaCategoryList
 struct JigyasaCategoryList: Codable {
let status, updatedDate, createdDate, jigyasaCategoryImageID: String
let jigyasaSanskrit, jigCateID: String
let jigyasa: [Jigyasa]
let updatedBy, createdBy, jigyasaHindi, jigyasaEnglish: String

enum CodingKeys: String, CodingKey {
    case status
    case updatedDate = "updated_date"
    case createdDate = "created_date"
    case jigyasaCategoryImageID = "jigyasa_category_image_id"
    case jigyasaSanskrit = "jigyasa_sanskrit"
    case jigCateID = "jig_cate_id"
    case jigyasa
    case updatedBy = "updated_by"
    case createdBy = "created_by"
    case jigyasaHindi = "jigyasa_hindi"
    case jigyasaEnglish = "jigyasa_english"
}
}

// MARK: - Jigyasa
struct Jigyasa: Codable {
let image1: String
let nameEnglish: String
let image5: String
let nameSanskrit: String
let images, image2: String
let nameHindi: String
let image4, image3: String
let jigyasaID: String

enum CodingKeys: String, CodingKey {
    case image1
    case nameEnglish = "name_english"
    case image5
    case nameSanskrit = "name_sanskrit"
    case images, image2
    case nameHindi = "name_hindi"
    case image4, image3
    case jigyasaID = "jigyasa_id"
}
}


 var jigyasaData = [JigyasaCategoryList]() ///--  this array

if let file = Bundle.main.url(forResource: "JsonFile", withExtension: "json")   {
    do {
        let data = try Data(contentsOf: file)

         // let data  = JSON(value)

         let decoder = JSONDecoder()
         let user = try decoder.decode(JigyasaModel.self, from: data)
         print(user.jigyasaCategoryList.count)       
          jigyasaData = user.jigyasaCategoryList
          collectionView.reloadData() //-- reload collection view

         }
    catch {
              print(error.localizedDescription)
           }
         }




 //--- collection view data source 

func numberOfSections(in collectionView: UICollectionView) -> Int
{
     return jigyasaData.count

}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {

    return  jigyasaData[section].jigyasa.count
}


  func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as? Yourcell


    let imagStrng = jigyasaData[indexPath.section].jigyasa[indexPath.row].image3
    return cell 
}
