Swift - Set CollectionView corner radius

Question

how do I set a corner radius on my UICollectionView?

Just to be clear, I actually mean the CollectionView itself, not the cells.

let theCollectionView: UICollectionView = {
    let v = UICollectionView(frame: CGRect.zero, collectionViewLayout: UICollectionViewFlowLayout())
    v.translatesAutoresizingMaskIntoConstraints = false
    v.backgroundColor = .white
    v.contentInsetAdjustmentBehavior = .always

    return v
}()

For all UIView , you can use:

theCollectionView.layer.cornerRadius = 10 // or whatever radius value you want
theCollectionView.clipsToBounds = true
