How to Add Shadow to TableView Without MasksToBound = False - swift

Question

When I add a shadow to my table view, it only shows if I have masksToBound = false as in picture 2. But it will look glitchy. Otherwise it looks fine scrolling up and down as in picture 1 but there's no shadow because I don't set it to false. Changing clipToBounds won't help either. My tableView changes height based on the input into the textField so I think adding a container view might be tricky.
How do I fix this? Is there a simple solution?
#IBOutlet weak var txtSearchBar: UITextField!
#IBOutlet weak var tblList: UITableView!
#IBOutlet weak var textField: UITextField!
#IBOutlet weak var titleLabel: UILabel!
#IBOutlet weak var shadowView: UIView!
#IBOutlet weak var tblHeightConstraint: NSLayoutConstraint!
#IBOutlet weak var shadowHeightConstraint: NSLayoutConstraint!
#IBOutlet weak var collectionView: UICollectionView!

//**glitchy if masksToBounds = false**
