else condition Collectionview rows not showing in swift

I am using two collectionviews and showing and hiding them according to conditions

initially i want to show newCollectionview with newArray images

code for collectionviews: with this code isEdit condition working perfectly.. but inatially when i upload images from picker then in cellForItemAt else condition not calling and added images(newArray) are also not showing in newCollectionView

here numberOfItemsInSection else return self.newArray.count is calling and count showing but the images not showing in newCollectionView

struct ImagesModel{

public var image : String?
init(image: String?) {
    self.image = image
}
}


import UIKit

class BidPlaceVC: UIViewController, UITextViewDelegate {

var oldArray = [ImagesModel]()
var newArray = [UIImage]()

override func viewDidLoad() {
    super.viewDidLoad()
    
    let layout = UICollectionViewFlowLayout()
    
    layout.sectionInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
    
    layout.scrollDirection = .horizontal
    let width = UIScreen.main.bounds.width/4.1
    let height = width*1.1
    
    layout.minimumInteritemSpacing = 0
    layout.minimumLineSpacing = 5
    layout.itemSize = CGSize(width: width, height: 100)

    self.newCollectionView.collectionViewLayout = layout
    
    self.oldCollectionnview.collectionViewLayout = layout

    newCollectionView.reloadData()
    oldCollectionnview.reloadData()
 }

 func uploadServiceCall() {

    let param = ["service_request" : bserviceId!, "amount" : amountTf.text ?? "100", "no_of_hours" : "2", "description" : proposalTextView.text ?? ""] as [String : Any]
    var imgData = [Data]()
    for image in self.newArray {
        imgData.append(image.jpegData(compressionQuality: 0.5)!)
    }
    APIReqeustManager.sharedInstance.uploadMultipleImagesWithParam(url: CommonUrl.place_bid, imagesData: imgData, imageKey: "files", parameters: param, vc: self, loaderNeed: true, completionHandler: {(responseData) in
        DispatchQueue.main.async {
            self.newCollectionView.reloadData()
