 func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return pendingImageString.count + 1 // + 1 for last cell
}

override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

    let cell : CollectionViewCell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as! CollectionViewCell
     cell.btn.tag = indexPath.row

     if indexPath.item = pendingImageString.count {
       cell.imageview = //your static image that is shown in last cell
       cell.cancelButton.isHidden = true
     }
     else{
         let img:NSString = pendingImageString[indexPath.item]
         cell.editImage.sd_setImageWithURL(NSURL(string: imageApikey + (img as String)))
         cell.cancelButton.isHidden = false
     }

}

override func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
     if indexPath.item = pendingImageString.count{
       // update your array with new image file
     }
}

// cancel button action
func buttonClicked(sender: UIButton?) {
    let tag = sender.tag
        // remove object from array and reload collectionview        
}

On click of last cell of the collection view add logic to enter your product in the database then just reload the collection view 

   func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
        if indexPath.row == pendingImageString.count - 1
        {
            //TODO - add item to database and reload collectionview
        }
    }
