Unable to check "If" Conditions for two Collectionview Arrays in swift

I have Two collectionviews. 1)newCollectionview 2) oldCollectionview

if i add any image in newCollectionview then

• initially i need to show newCollectionview with newArray images

if i am coming from isEdit

• if isEdit == true

  if oldArray.isEpty == false -----> oldCollectionview with oldArray

  if i add only new images where oldArray images are not present

  if newArray.isEpty == false -----> newCollectionview with newArray

  if i add new images where oldArray images are present

  if oldArray.isEpty == false && newArray.isEpty == false -----> oldCollectionview and newCollectionview

for that condition i have tried like below: with this code i am not able to show initially newArray with newCollectionview and even if isEdit true then also if there are images in oldArray then only i am able to show newArray with newCollectionview... if i add more then oldArray images to newCollectionview then those images are not showing in newCollectionview but those are added in JSON but not showing in newCollectionview... why?

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


if isEdit{

    if oldArray.isEmpty == false{

       if collectionView == oldCollectionview{

        return  oldArray.count
         }
    }

    if newArray.isEmpty == false{
        if collectionView == newCollectionView{
           return  self.newArray.count
         }
    }

    if oldArray.isEmpty == false && newArray.isEmpty == false{

        if collectionView == oldCollectionview{
         return  oldArray.count
          }
         if collectionView == newCollectionView{
            return  self.newArray.count
          }
    }
}
else{

    if collectionView == newCollectionView{
       return  self.newArray.count
     }
}
return newArray.count
}




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

if isEdit{

    if oldArray.isEmpty == false{

        if collectionView == oldCollectionview{

            let cell = oldCollectionview.dequeueReusableCell(withReuseIdentifier: "FilesCollectionCell", for: indexPath) as? FilesCollectionCell

            let img = "\(CommonUrl.bidsAttachment)\( self.oldArray[indexPath.item].image ?? "")"
            cell?.imgView.getImage(withUrl: img, placeHolder: #imageLiteral(resourceName: "home"), imgContentMode: .scaleAspectFill)
        }

    }
    if newArray.isEmpty == false{
         if collectionView == newCollectionView{

            let cell = newCollectionView.dequeueReusableCell(withReuseIdentifier: "FilesCollectionCell", for: indexPath) as? FilesCollectionCell
             cell?.imgView.image = self.newArray[indexPath.item]

             return cell!
         }

     }

    if oldArray.isEmpty == false && newArray.isEmpty == false{

        if collectionView == oldCollectionview{

            let cell = oldCollectionview.dequeueReusableCell(withReuseIdentifier: "FilesCollectionCell", for: indexPath) as? FilesCollectionCell
            let img = "\(CommonUrl.bidsAttachment)\( self.oldArray[indexPath.item].image ?? "")"
            cell?.imgView.getImage(withUrl: img, placeHolder: #imageLiteral(resourceName: "home"), imgContentMode: .scaleAspectFill)
          
               return cell!
        }
        if collectionView == newCollectionView{

           let cell = newCollectionView.dequeueReusableCell(withReuseIdentifier: "FilesCollectionCell", for: indexPath) as? FilesCollectionCell
            cell?.imgView.image = self.newArray[indexPath.item]

            return cell!
        }

    }
}
else{
    if collectionView == newCollectionView{

       let cell = newCollectionView.dequeueReusableCell(withReuseIdentifier: "FilesCollectionCell", for: indexPath) as? FilesCollectionCell
        cell?.imgView.image = self.newArray[indexPath.item]

        return cell!
    }
    
}
return UICollectionViewCell()

}
}

please do help with condition check
