How to add Multiple Section UICollectionViewCells in one view

I’m trying to build multiple section uicollectionview in the same view the first collection view working fine but when I added the second one the app crashed (lldb),
both are custom cells define a suprate classes i used if statement as showing in this Answer: https://stackoverflow.com/a/44692356/8386142?stw=2 the code is clear no errors it just crashed like there is something wrong with constraints (lldb)
here is the code that I used to build it the

import UIKit

struct areaCustomCellData {
    var lable: String
}

struct storesCustomCellData {
    var lable: String
}

class Search: UIViewController {

    let data = [
     areaCustomCellData(lable: "شرق النيل"),
     areaCustomCellData(lable: "بحري"),
     areaCustomCellData(lable: "امدرمان"),
     areaCustomCellData(lable: "الخرطوم"),
    ]

    let storesData = [
     storesCustomCellData(lable: "شرق النيل"),
     storesCustomCellData(lable: "بحري"),
     storesCustomCellData(lable: "امدرمان"),
     storesCustomCellData(lable: "الخرطوم"),
    ]

    let areaCView: UICollectionView = {
       let layout = UICollectionViewFlowLayout()
        layout.scrollDirection = .horizontal
       let cv = UICollectionView(frame: .zero, collectionViewLayout: layout)
        cv.translatesAutoresizingMaskIntoConstraints = false
        cv.register(customCell.self, forCellWithReuseIdentifier: "areaCell")
        cv.backgroundColor = UIColor(red: 245, green: 245, blue: 245, a: 1)
        cv.showsHorizontalScrollIndicator = false
       return cv
    }()

    let storesCView: UICollectionView = {
       let layout = UICollectionViewFlowLayout()
        layout.scrollDirection = .vertical
       let cv = UICollectionView(frame: .zero, collectionViewLayout: layout)
        cv.translatesAutoresizingMaskIntoConstraints = false
        cv.register(customCell2.self, forCellWithReuseIdentifier: "storesCell")
        cv.backgroundColor = UIColor(red: 245, green: 245, blue: 245, a: 1)
        cv.showsVerticalScrollIndicator = false
       return cv
    }()

    override func viewDidLoad() {
        super.viewDidLoad()

        self.view.backgroundColor = UIColor(red: 245, green: 245, blue: 245, a: 1)
        view.addSubview(areaCView)
        view.addSubview(storesCView)

        storesCView.delegate = self
        storesCView.dataSource = self
        areaCView.delegate = self
        areaCView.dataSource = self

        setUpLayout()
        setUpNavBar()
        setUpSearchBar()

    }

    func setUpLayout(){
        areaCView.topAnchor.constraint(equalTo: view.topAnchor, constant: 120).isActive = true
        areaCView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
        areaCView.trailingAnchor.constraint(equalTo: view.trailingAnchor,constant: -20).isActive = true

    }

        return 2
    }

        return (section == 0) ? data.count : storesData.count
    }
