Position is Ambiguous for UILabel Warning for label I added programmatically

Hi, I have added a UILabel to my collection view cell programmatically and have set up constraints using auto layout. The centerX and centerY constraints of the label are equal to the centerX and centerY anchors of the content view. However, the label is appearing in the top left corner of the cell rather than in the center where I expect it to be.

Here is my code:

protocol TapLabelCollectionViewCellDelegate: AnyObject {
    func incrementNumberOfTaps(index: Int)
}

class TapLabelCollectionViewCell: UICollectionViewCell {
    var taplabel: UILabel!
    
    var delegate: TapLabelCollectionViewCellDelegate?
        
    var index: Int!
    
    static let identifier = "tapLabelCellIdentifier"
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        
        taplabel = UILabel()
        taplabel.translatesAutoresizingMaskIntoConstraints = false
        addSubview(taplabel)
        NSLayoutConstraint.activate([
            taplabel.centerXAnchor.constraint(equalTo: contentView.centerXAnchor),
            taplabel.centerYAnchor.constraint(equalTo: contentView.centerYAnchor)
        ])
        
        setUpTapGestureRecognizer()
    }
    
    required init?(coder: NSCoder) {
        super.init(coder: coder)
    }
    
    func setUpTapGestureRecognizer() {
        let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(incrementNumberOfTaps))
        print("tap Label,", taplabel)
        taplabel.addGestureRecognizer(tapGestureRecognizer)
    }
    
    @objc func incrementNumberOfTaps() {
        delegate?.incrementNumberOfTaps(index: index)
    }
}

I am also getting the following warning in Xcode
