How to make an image radius in a collection view?

Question

I would like to make a radius for my collection view to make the pictures a little more round. I have tried adding in the viewdidload() function the following:

mine.photo.layer.cornerRadius = 10

mine is another class that I have with the IBOutlet photo: UIImageView!.

What I have to make my collection view neat are the following functions:

extension DiscoverViewController: UICollectionViewDelegateFlowLayout {
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
        return 15
    }

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat {
        return 0
    }

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        //dude.photo.layer.cornerRadius = 10
        return CGSize(width: collectionView.frame.size.width / 2 - 2.5, height: collectionView.frame.size.width / 1.5 - 1 )

    }
}

Any ideas?

Answer 1

The round you need should be inside the cell class

class CellColl:UICollectionViewCell {
 @IBOutlet weak var photo: UIImageView!
   override func awakeFromNib() {
      super.awakeFromNib()
      self.photo.layer.cornerRadius = 10
      self.photo.clipsToBounds = true
   }
}
