Needs to show the list of items in label with based on the format coming from response

I have an api call response where i will get the list of items as two format.

"items" : [
      {
        "menu_code" : "NDS",
        "name" : "Monday"
      },
      {
        "menu_code" : "NDN",
        "name" : "Tuesday"
      }
    ]

format 2 is here :

"items" : [
      {
        "unit" : "Nos",
        "name" : "Chapathi\/Pulkas",
        "quantity" : 2
      },
      {
        "unit" : "Cup",
        "name" : "Palya\/Curry",
        "quantity" : 1
      }
    ]

Now i have one label in my collection view. So based the response in my label i needs to show like below example :

name - quantity unit , name - quantity unit, name - quantity unit ...etc based on the count coming from response.

Another format :

name - menu_code, 
name - menu_code, 
name - menu_code ..etc

based on the count coming from response.

My model class :

struct Item : Codable {

    let unit : String?
    let name : String?
    let quantity : Int?
    let menuCode : String?

}

my collection view :

var names:[String] = []
    var qty:[Int] = []
    var unit:[String] = []
    var menuCode:[String] = []

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "HomeCollectionCell", for: indexPath) as! HomeCollectionCell

  cell.productName.text = self.allCategory[indexPath.item].menuName
  let itemsData = self.allCategory[indexPath.row].items

    print(itemsData)

    for dt in itemsData {
       // print(dt)
        let nam = dt.name
        let unt = dt.unit
        let mCode = dt.menuCode
        let qtys = dt.quantity

        names.append(nam ?? "")
        unit.append(unt ?? "" )
        qty.append(qtys ?? 0)
        menuCode.append(mCode ?? "" )
       // cell.ProductsubLabel.text = itemsData


    }
return cell
}

So i have created an array but not sure how to append to label.And also i am not aware to difference the two format and to show in the label.Any help on this.

Thanks in advance !

Update :

third new format :

"items" : [
          {
            "unit" : "Nos",
            "product_name" : "Chapathi\/Pulkas",
            "quantity" : 2
          },
          {
            "unit" : "Cup",
            "product_name" : "Palya\/Curry",
            "quantity" : 1
          }
        ]

A quite efficient solution is to add a description property in the struct which returns the appropriate data. If unit does not exist return the menuCode information otherwise quantity and unit

struct Item : Codable {

    let unit : String?
    let name : String?
    let productName : String?
    let quantity : Int?
    let menuCode : String?

    var description : String {
        let name = self.name ?? self.productName ?? "n/a"
        if unit == nil {
            return "\(name) - \(menuCode!)"
        } else {
            return "\(name) - \(quantity!) \(unit!)"
        }
    }
}

In cellForItemAt map the items to their descriptions and join the array by comma.

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "HomeCollectionCell", for: indexPath) as! HomeCollectionCell

    let category = self.allCategory[indexPath.item]
    cell.productName.text = category.menuName

    let itemsData = category.items
    let subData = itemsData.map {$0.description}.joined(separator: ", ")
    cell.ProductsubLabel.text = subData

    print(subData)
    return cell
}

And delete the four ugly arrays above cellForItemAt
