IBOutlets in UICollectionView are nil - Swift

When I print the IBOutlets I declared in MyCell class, they come out to be nil.

Methods in ViewController

public override func viewDidLoad() {
    super.viewDidLoad()
    self.seriesCollectionView.register(MyCell.self, forCellWithReuseIdentifier: "MyCell")
}

public func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "MyCell", for: indexPath) as! MyCell
    cell.setup()

    return cell
}

MyCell class

class MTSeriesViewCell: UICollectionViewCell {
@IBOutlet weak var cellView: UIView!

@IBOutlet weak var cellImageView: UIImageView!
override func awakeFromNib() {
    super.awakeFromNib()
}

public func setup() {
    print(cellView)
}

}

Is there any other way I should be initializing/registering MyCell class in viewDidLoad of ViewController?
