Swift cells are created but don't show up in UICollectionView swift 5

Question

I'm creating a collection view with custom collection view cell. So, I've created the collection view in my storyboard view controller. The problem is that my cells are created in cellForItemAt but they are not shown at all, I've also tried using default cells, but they are not shown either, and of course, I've tried all the solutions I found. Thank you for helping in advance!

        collectionView.dataSource = self
        
        title = set?.name
        
        
        
        collectionView!.register(WordCollectionViewCell.self, forCellWithReuseIdentifier: Identifies.WordCollectionViewCellIdentifier)
        
        
        let buttonItem  = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addButtonPressed))
        
        
        navigationItem.rightBarButtonItem = buttonItem
        updateTranslations()
    }

your awakeFromNib method is probably firing before your set your cell's translation property. Try setting your label text in your translation's setter:

    set {
        _translation = newValue
        wordLabel?.text = _translation?.word
    }
