Ошибка инициализации UINib приводит к EXC_BREAKPOINT (код = 1, субкод = 0x1a3a6e6d4)

Question

У меня есть приложение для магазина, разработанное в swift 3, и я перешел на swift4 и внес некоторые изменения. В моем приложении все элементы, которые будут инициализировать UINib, вызовут ошибки, которые я не могу отследить по их причине. Xcode ide показывает эту ошибку во время выполнения:

EXC_BREAKPOINT (код = 1, субкод = 0x1a3a6e6d4)

Когда я вызываю такие строки:

let uiNib = UINib(nibName: "ProductCollectionViewCell", bundle: Bundle(identifier: "ProductCollectionViewCell"))

Я сделал это с помощью try / catch, но xCode сказал error block is unrreachable because no errors are thrown.

Обновление:

-------------------------------------------- -------------

Я нашел ошибку из-за этого выражения:

Bundle(identifier: "ProductCollectionViewCell")  

Когда я заменил связку с Nil приложение продолжало и работало без ошибок. Поэтому мне интересно, почему это работает в Swift3, а не в Swift4? ----------------------------------------------- ----------

Вот реализация ProductCollectionViewCell:

ProductDetailsCollectionViewCell.swift

import UIKit
import Alamofire

class ProductDetailsCollectionViewCell: UICollectionViewCell {

    var request: Alamofire.Request?

    @IBOutlet var AlbumImage : UIImageView?
    @IBOutlet var nameLbl: UILabel!
    @IBOutlet var amountLbl: UILabel!

    override func awakeFromNib() {
        super.awakeFromNib()
        amountLbl.textColor = UIColor.productPriceColor()

        if appDelegate.langStr != "en" {
            nameLbl.transform = CGAffineTransform(scaleX: -1.0,y: 1.0)
            amountLbl.transform = CGAffineTransform(scaleX: -1.0,y: 1.0)
            AlbumImage?.transform=CGAffineTransform(scaleX: -1, y: 1);
        }

    }
}

И ProductDetailsCollectionViewCell.xib:
